The duration for pulpal necrosis, or death of the dental nerve, is variable and dependent on several factors. It is not a process with a fixed, predictable timeline. Damage to the nerve, typically resulting from deep decay, trauma, or extensive dental procedures, initiates the process. The nerve’s vulnerability is directly related to the severity and persistence of the damaging stimuli. For example, a rapidly progressing cavity exposing the pulp will likely lead to a quicker nerve demise compared to a slowly developing crack in the tooth.
Understanding the timeframe for nerve death is crucial for effective dental treatment planning. A vital, albeit inflamed, nerve may be salvageable with procedures like pulpotomy or root canal therapy. However, a necrotic nerve necessitates root canal treatment or extraction to prevent infection and further complications, such as abscess formation. Delayed intervention can lead to increased pain, bone loss, and systemic health issues. Historically, tooth extractions were the only solution for infected teeth; modern endodontic techniques aim to preserve natural teeth, highlighting the importance of timely diagnosis and treatment.
The subsequent sections will elaborate on the causes of pulpal necrosis, the symptoms indicating nerve damage, diagnostic methods employed by dentists, and the available treatment options, emphasizing the significance of prompt dental care in managing pulpal health.
1. Trauma Severity
The extent of traumatic injury to a tooth is a primary determinant in the timeline for pulpal necrosis. The more severe the trauma, the greater the likelihood of compromised blood supply and accelerated nerve degeneration.
-
Tooth Displacement (Luxation or Avulsion)
Significant displacement of a tooth, such as luxation (partial displacement) or avulsion (complete displacement), disrupts the delicate neurovascular bundle entering the apical foramen. Avulsion, particularly, severs the blood supply entirely. Replantation of an avulsed tooth can sometimes re-establish circulation, but the likelihood diminishes with prolonged extra-oral time. Consequently, avulsion events often result in pulpal necrosis unless revascularization occurs promptly. The severity of luxation also dictates the degree of vascular damage and the probability of subsequent nerve death.
-
Crown or Root Fractures
Fractures extending into the pulp chamber directly expose the nerve tissue to the oral environment, introducing bacteria and inflammatory mediators. Vertical root fractures can also sever blood vessels. The depth and extent of the fracture correlate directly with the rapidity of pulpal involvement and subsequent necrosis. A crown fracture exposing a large portion of the pulp necessitates immediate intervention to protect the nerve, while root fractures often lead to irreversible damage.
-
Concussion and Subluxation
Even without visible displacement or fracture, a tooth may sustain concussion or subluxation (loosening). While the neurovascular bundle remains intact, inflammation and edema within the pulp can compress blood vessels, leading to ischemia. The duration and intensity of this ischemia are crucial. Mild concussion may result in reversible pulpitis, whereas severe concussion or subluxation can trigger progressive pulpal necrosis over weeks or months as the compromised blood supply fails to sustain the nerve tissue.
-
Associated Alveolar Bone Fracture
Trauma severe enough to fracture the surrounding alveolar bone often involves significant vascular damage not only to the tooth but also to the supporting tissues. This compromised regional blood supply further reduces the tooth’s ability to recover, accelerating the progression toward pulpal necrosis. Bone fractures increase inflammation and impede nutrient delivery, contributing to the eventual demise of the dental nerve.
The varying degrees of trauma severity directly impact the longevity of the dental nerve. While mild concussions might allow for pulpal recovery, severe events like avulsions or root fractures often lead to predictable and rapid nerve death. The immediate management of dental trauma is paramount in mitigating damage and potentially preserving pulpal vitality.
2. Infection Rate
The rate of infection profoundly influences the timeframe for pulpal necrosis. A rapid, aggressive infection accelerates nerve degeneration, while a slower, more contained infection allows for a potentially prolonged period before complete nerve death.
-
Virulence of Pathogens
The types and virulence of bacteria invading the pulp significantly impact the speed of necrosis. Highly virulent pathogens, such as certain strains of Streptococcus or anaerobic bacteria, produce potent toxins and enzymes that rapidly destroy pulp tissue. A polymicrobial infection, involving a diverse community of bacteria, often exhibits synergistic virulence, leading to a faster progression of inflammation and necrosis compared to infections involving less aggressive species. The presence of specific enzymes like collagenase and hyaluronidase, secreted by certain bacteria, further accelerates tissue breakdown.
-
Access Route and Size of Exposure
The pathway through which bacteria access the pulp and the size of the exposure dictate the initial bacterial load and subsequent infection rate. A large carious lesion directly exposing a significant portion of the pulp introduces a substantial number of bacteria, resulting in a rapid and widespread infection. Microscopic cracks or dentinal tubules provide slower, more limited access, leading to a less immediate and potentially more localized infection. The presence of a restoration with microleakage can also provide a continuous, albeit limited, bacterial supply to the pulp, contributing to a chronic, low-grade infection.
-
Host Immune Response
The host’s immune response plays a critical role in modulating the infection rate. A robust immune response can effectively contain the infection, slowing the progression of pulpal damage and potentially allowing for repair in some cases. However, an overwhelming or dysregulated immune response can paradoxically exacerbate tissue damage through excessive inflammation. Immunocompromised individuals, such as those with diabetes or undergoing chemotherapy, exhibit a diminished immune response, rendering them more susceptible to rapid and aggressive pulpal infections.
-
Presence of Pre-existing Pulpitis
The pre-existence of pulpitis, whether reversible or irreversible, influences the susceptibility of the pulp to further infection. A chronically inflamed pulp, already compromised by inflammation and reduced blood flow, is more vulnerable to rapid necrosis upon subsequent bacterial invasion. The inflammatory mediators present in a pre-inflamed pulp prime the tissue for accelerated damage, leading to a quicker demise of the nerve tissue. Acute exacerbations of chronic pulpitis are common, resulting in a rapid shift from a slow, smoldering infection to an aggressive, destructive process.
In conclusion, the interplay between pathogen virulence, access route, host immune response, and pre-existing pulpal conditions determines the infection rate and, consequently, the timeframe for pulpal necrosis. Understanding these factors is crucial for clinicians in assessing the prognosis of an affected tooth and determining the appropriate course of treatment.
3. Blood Supply
The integrity of the dental pulp’s blood supply is paramount for its vitality. Compromise to this vascular network directly impacts the timeframe for pulpal necrosis. The pulp, richly supplied by arterioles and venules entering through the apical foramen, relies on this blood flow for oxygen, nutrients, and waste removal. Interruption or reduction in blood supply initiates a cascade of events leading to nerve degeneration.
-
Vessel Compression due to Inflammation
Inflammation, resulting from caries, trauma, or operative procedures, causes edema within the confined space of the pulp chamber. This increased pressure compresses blood vessels, reducing blood flow to the nerve tissue. Prolonged compression leads to ischemia (oxygen deprivation), initiating irreversible cellular damage and eventual necrosis. The degree and duration of inflammation are directly proportional to the extent of vascular compromise and the acceleration of nerve death. Examples include untreated deep caries causing chronic inflammation and subsequent vascular collapse.
-
Traumatic Severance of Apical Vessels
Dental trauma, such as luxation or avulsion, can sever the apical vessels supplying the pulp. Avulsion, where the tooth is completely displaced from its socket, invariably severs the blood supply. Luxation, involving partial displacement, may stretch or tear the vessels. The immediate interruption of blood flow deprives the pulp of essential oxygen and nutrients, leading to rapid necrosis. The success of replantation after avulsion largely depends on the re-establishment of blood flow to the pulp; delayed replantation reduces the likelihood of revascularization and increases the probability of nerve death.
-
Calcific Metamorphosis and Pulp Canal Obliteration
In some cases, trauma or chronic irritation can trigger calcific metamorphosis, a process where the pulp chamber and root canal space gradually become filled with calcified tissue. While not a direct severance, this process obliterates the vascular space, effectively reducing blood flow to the remaining pulp tissue. This gradual reduction in blood supply can lead to slow, progressive pulpal necrosis over an extended period, often without acute symptoms. Radiographic evidence of pulp canal obliteration indicates a compromised vascular environment and an increased risk of eventual nerve death.
-
Systemic Conditions Affecting Microcirculation
Certain systemic diseases, such as diabetes mellitus, atherosclerosis, and sickle cell anemia, can impair microcirculation throughout the body, including the dental pulp. These conditions reduce blood flow to the pulp, making it more susceptible to ischemic damage and accelerated necrosis. Diabetic patients, for instance, often exhibit compromised wound healing and increased susceptibility to infections, exacerbating pulpal inflammation and accelerating nerve death. The presence of these systemic conditions should be considered when assessing the prognosis of teeth with pulpitis or following dental trauma.
In summary, the blood supply is a critical determinant of pulpal vitality. Compromise to this vascular network, whether through inflammation, trauma, calcification, or systemic disease, directly influences the timeframe for pulpal necrosis. The extent and duration of blood flow disruption dictate the speed at which the nerve degenerates, emphasizing the importance of maintaining pulpal blood supply through preventative measures and prompt treatment interventions.
4. Tooth Location
The tooth’s position within the oral cavity influences the timeframe for pulpal necrosis. Variations in anatomy, blood supply, and susceptibility to trauma or decay, based on tooth location, affect the rate at which the nerve degenerates following insult.
-
Proximity to Maxillary Sinus (Posterior Maxillary Teeth)
Posterior maxillary teeth, particularly molars, exhibit close anatomical proximity to the maxillary sinus. Inflammation or infection originating in the pulp of these teeth can readily spread to the sinus, causing sinusitis. This proximity also means that sinus infections can sometimes mimic or exacerbate pulpal symptoms, complicating diagnosis. Moreover, the blood supply to these teeth may be indirectly affected by sinus inflammation. The faster spread of infection due to this proximity can lead to a quicker progression of pulpal necrosis compared to teeth located further from the sinus.
-
Root Morphology and Apical Foramina (Molars vs. Incisors)
Molars, with their multiple roots and complex root canal systems, present a greater surface area for bacterial colonization and a more intricate pathway for infection to spread throughout the pulp. The presence of accessory canals and multiple apical foramina can complicate treatment and increase the likelihood of persistent infection, potentially accelerating nerve death if not properly managed. In contrast, incisors, with their single roots and simpler canal anatomy, may exhibit a slower progression of necrosis if the primary apical foramen remains relatively patent, allowing for some degree of drainage or immune response.
-
Susceptibility to Trauma (Anterior Teeth)
Anterior teeth are more prone to traumatic injuries due to their prominent position in the dental arch. Incisal edges are frequently involved in accidental impacts, leading to fractures, luxations, or avulsions. These traumatic events disrupt the blood supply to the pulp, often resulting in rapid pulpal necrosis. The exposed position of anterior teeth increases their vulnerability to external forces, accelerating the timeline for nerve death following trauma compared to more protected posterior teeth.
-
Salivary Flow and Caries Risk (Posterior Teeth)
Posterior teeth, particularly molars and premolars, are located in areas of reduced salivary flow, creating a more conducive environment for bacterial accumulation and caries development. The fissures and grooves on the occlusal surfaces of these teeth provide retentive sites for plaque and food debris, increasing the risk of deep caries extending into the pulp. The subsequent rapid infection associated with these lesions accelerates the progression to pulpal necrosis. Limited access for oral hygiene in posterior regions further exacerbates the risk of caries and subsequent pulpal involvement.
The tooth’s anatomical location significantly influences its vulnerability to factors that precipitate pulpal necrosis. Location-specific differences in blood supply, susceptibility to trauma and caries, and proximity to adjacent structures contribute to variations in the timeframe for nerve death following insult. Understanding these location-dependent factors is crucial for accurate diagnosis, treatment planning, and preventative strategies in endodontic care.
5. Patient Health
Systemic health status significantly influences the timeframe for pulpal necrosis. A patient’s overall health impacts immune response, vascular function, and healing capacity, thereby affecting the pulp’s ability to withstand infection, trauma, or inflammation. Compromised systemic health typically accelerates nerve degeneration. For example, individuals with uncontrolled diabetes exhibit impaired microcirculation and a diminished immune response. Consequently, pulpal inflammation progresses more rapidly, leading to a quicker demise of the dental nerve following carious exposure or traumatic injury. Similarly, immunocompromised patients, such as those undergoing chemotherapy or living with HIV/AIDS, are more susceptible to opportunistic infections, potentially leading to rapid pulpal necrosis due to overwhelming bacterial invasion. The pulp’s resilience and ability to recover are inherently linked to the host’s overall physiological state.
Cardiovascular health is another critical factor. Conditions like atherosclerosis and hypertension can compromise blood flow to the pulp, reducing its capacity to withstand inflammatory challenges. Reduced blood supply exacerbates ischemia, accelerating cellular damage within the pulp and shortening the survival time of the dental nerve. Practical implications of this connection manifest in treatment planning. Dentists must carefully assess the patient’s medical history and consider systemic conditions when evaluating the prognosis of a tooth with pulpitis or after a traumatic injury. Modification of treatment approaches, such as antibiotic prophylaxis or more conservative restorative techniques, may be warranted in patients with compromised systemic health to mitigate the risk of rapid pulpal necrosis. For instance, a patient with a history of radiation therapy to the head and neck region may require meticulous oral hygiene instruction and frequent fluoride applications to prevent caries, thus minimizing the risk of pulpal involvement.
In conclusion, the patient’s systemic health is an integral component in determining the rate of pulpal necrosis. Existing health conditions influence the pulp’s ability to respond to insult and repair itself. Ignoring this crucial link can lead to inaccurate diagnoses and ineffective treatment strategies. A comprehensive understanding of the patient’s medical history, coupled with appropriate clinical and radiographic examination, is essential for predicting the timeline for pulpal necrosis and implementing interventions to preserve pulpal vitality or manage infection effectively. Addressing the systemic factors contributing to pulpal vulnerability is paramount for achieving long-term dental health.
6. Inflammation duration
The duration of pulpal inflammation is a critical determinant in the timeframe for nerve necrosis. The longer the inflammatory stimulus persists, the greater the likelihood of irreversible damage and subsequent nerve death. The inflammatory response, initially intended to protect the pulp, can become self-destructive if unresolved. Prolonged inflammation compromises blood supply, induces cellular damage, and ultimately leads to pulpal necrosis.
-
Reversible vs. Irreversible Pulpitis
Reversible pulpitis represents an early stage of inflammation where the pulp retains the capacity to heal following removal of the irritant. Symptoms are typically mild and transient, such as sensitivity to cold stimuli. If the irritant, like a small carious lesion, is addressed promptly, the inflammation subsides, and the pulp recovers. However, if the irritant persists, reversible pulpitis can progress to irreversible pulpitis. Irreversible pulpitis is characterized by more severe and persistent pain, often spontaneous in nature. At this stage, the pulp’s ability to heal is significantly compromised, and prolonged inflammation invariably leads to necrosis. The transition from reversible to irreversible pulpitis marks a critical juncture in determining the timeframe for nerve death.
-
Chronic Low-Grade Inflammation
Chronic low-grade inflammation, often resulting from microleakage around restorations or slowly progressing caries, can persist for extended periods without causing acute symptoms. While the initial inflammatory response may be minimal, the continuous exposure to bacterial byproducts gradually damages the pulp tissue. Over time, this chronic inflammation compromises the pulp’s blood supply and cellular integrity, leading to a slow but steady progression toward necrosis. The prolonged duration of this low-grade inflammation allows for adaptive changes within the pulp, making diagnosis challenging and potentially delaying necessary intervention. This extended inflammatory period inevitably reduces the pulp’s regenerative capacity, making necrosis almost certain.
-
Inflammatory Mediators and Cellular Damage
The duration of inflammation directly correlates with the accumulation of inflammatory mediators, such as cytokines, prostaglandins, and neuropeptides, within the pulp. These mediators, while initially intended to promote healing and immune response, become destructive when present in excess for prolonged periods. They contribute to vasodilation, edema, and the recruitment of inflammatory cells, leading to increased intrapulpal pressure and vascular compression. Furthermore, these mediators directly damage pulpal cells, including odontoblasts and nerve fibers, through mechanisms like oxidative stress and apoptosis. The longer the exposure to these inflammatory mediators, the greater the cellular damage and the faster the progression to irreversible pulpitis and eventual necrosis. For example, sustained release of TNF-alpha can lead to significant and irreversible pulpal damage over time.
-
Impact of Treatment Delay
Delayed treatment of pulpal inflammation, regardless of its cause, significantly shortens the timeframe for nerve survival. As inflammation persists untreated, the pulp’s capacity to recover diminishes. Delaying treatment allows for the progression of irreversible pulpitis, the exacerbation of inflammatory mediators, and the further compromise of the pulp’s blood supply. Prompt intervention, such as caries removal, pulpotomy, or root canal therapy, aims to eliminate the source of inflammation and prevent further pulpal damage. Delaying these procedures increases the likelihood of necrosis and necessitates more extensive and invasive treatments. The urgency of addressing pulpal inflammation underscores the direct relationship between treatment delay and the acceleration of nerve death.
In conclusion, the duration of inflammation is a pivotal factor influencing the survival of the dental nerve. The transition from reversible to irreversible pulpitis, the persistence of chronic low-grade inflammation, the accumulation of destructive inflammatory mediators, and the impact of treatment delay all contribute to a shortened timeframe for pulpal necrosis. Recognizing the significance of inflammation duration is essential for accurate diagnosis, timely intervention, and the preservation of pulpal vitality. The quicker the stimulus can be removed before the point of no return the better the result for the tooth.
7. Treatment delay
Treatment delay in addressing pulpal pathology directly impacts the timeframe for nerve necrosis. Prolonged delay permits the progression of reversible conditions to irreversible states, significantly diminishing the opportunity for pulpal preservation and accelerating nerve degeneration.
-
Progression of Caries and Bacterial Invasion
Delayed treatment of dental caries allows for continued bacterial proliferation and deeper penetration into the tooth structure. As the caries progresses closer to the pulp, the inflammatory response intensifies, and the risk of direct pulpal exposure increases. Once the pulp is exposed, bacteria rapidly invade the nerve tissue, accelerating the inflammatory process and hastening necrosis. Early intervention, such as caries removal and restoration, prevents pulpal involvement, while delayed treatment significantly reduces the likelihood of pulpal survival.
-
Exacerbation of Inflammation and Intrapulpal Pressure
Untreated pulpitis, regardless of its initial cause, leads to a sustained inflammatory response within the confined space of the pulp chamber. This prolonged inflammation causes increased intrapulpal pressure, compressing blood vessels and compromising blood flow to the nerve tissue. As ischemia worsens, cellular damage accelerates, and the nerve’s ability to recover diminishes. Delayed treatment allows for this inflammatory cascade to perpetuate, culminating in irreversible pulpitis and eventual necrosis. Prompt intervention to alleviate the inflammatory stimulus is critical in maintaining pulpal vitality.
-
Development of Periapical Pathology
As pulpal necrosis progresses, bacteria and their byproducts extend beyond the apical foramen, initiating inflammation in the periapical tissues. This periapical inflammation can manifest as a periapical abscess or granuloma, indicative of chronic infection and bone resorption. The presence of periapical pathology signals that the pulpal necrosis is well-established, and the tooth’s prognosis is significantly compromised. Delayed treatment allows for this spread of infection, further complicating treatment options and potentially affecting adjacent structures. Timely intervention prevents the development of periapical lesions and preserves the integrity of the surrounding tissues.
-
Compromised Treatment Options and Complexity of Intervention
The longer the delay in treatment, the more limited the options for preserving the tooth. Early intervention may allow for conservative procedures like direct pulp capping or pulpotomy, whereas delayed treatment often necessitates root canal therapy or extraction. Furthermore, delayed treatment can lead to more complex endodontic challenges, such as calcified canals, internal resorption, or procedural complications. These factors increase the complexity and cost of treatment and reduce the likelihood of a successful outcome. Early intervention maximizes the range of treatment options and simplifies the procedure, ultimately improving the prognosis and preserving the natural tooth.
These facets demonstrate that prompt dental intervention plays a crucial role in determining the fate of the dental nerve. The longer treatment is delayed, the faster the nerve’s demise. Early management of pulpal issues not only reduces the complexity of dental procedures but also enhances the potential for successful outcomes and the overall preservation of dental health.
Frequently Asked Questions
The following questions address common concerns related to the timeframe for pulpal necrosis and factors influencing its progression.
Question 1: How quickly does pulpal necrosis occur following a traumatic injury?
The speed of pulpal necrosis following a traumatic injury varies depending on the severity of the event. A complete avulsion, where the tooth is knocked out, results in immediate severance of the blood supply and rapid nerve death, potentially within days if reimplantation is unsuccessful. Less severe injuries, such as concussion or subluxation, may lead to slower necrosis over weeks or months, depending on the degree of vascular compromise.
Question 2: Can a tooth nerve die without any noticeable symptoms?
Yes, pulpal necrosis can sometimes occur asymptomatically, particularly in cases of slow, progressive damage, such as calcific metamorphosis or chronic low-grade inflammation. The gradual reduction in blood supply or the slow release of inflammatory mediators may not trigger acute pain. Routine radiographic examination can reveal signs of pulpal necrosis, such as periapical lesions or pulp canal obliteration, even in the absence of symptoms.
Question 3: Does the age of the patient affect the rate of pulpal necrosis?
Age-related changes in the pulp, such as decreased cellularity and reduced blood supply, can influence the rate of necrosis. Older individuals may exhibit a slower inflammatory response and a decreased capacity for pulpal repair, potentially leading to a more prolonged period before complete nerve death. However, the presence of systemic conditions, more prevalent in older adults, can also accelerate necrosis.
Question 4: Is pulpal necrosis always a result of dental caries?
While dental caries is a common cause, pulpal necrosis can result from various factors, including trauma, deep restorations, periodontal disease, and even idiopathic causes. Any insult that compromises the pulp’s blood supply or introduces bacteria can lead to inflammation and eventual necrosis. Identifying the underlying etiology is crucial for effective treatment planning.
Question 5: How does diabetes affect the timeframe for pulpal necrosis?
Diabetes mellitus, particularly when poorly controlled, impairs microcirculation and reduces the effectiveness of the immune response. This compromised vascularity and immune function make the pulp more susceptible to ischemic damage and infection, accelerating the progression to pulpal necrosis following exposure to caries or trauma. Diabetic patients often exhibit a faster rate of pulpal necrosis compared to non-diabetic individuals.
Question 6: Can root canal treatment reverse pulpal necrosis?
Root canal treatment cannot reverse pulpal necrosis. Once the nerve has died, the primary objective of root canal therapy is to remove the necrotic tissue, disinfect the root canal system, and seal it to prevent further infection. Root canal treatment aims to eliminate the source of inflammation and prevent periapical disease, not to revive the dead nerve.
Prompt diagnosis and treatment are essential in managing pulpal health and addressing potential complications stemming from nerve death.
The following section will outline treatment options and preventative care.
Tips Regarding the Timeline for Pulpal Necrosis
Understanding the factors influencing the timeframe for pulpal necrosis is crucial for effective dental care. These tips highlight key considerations for preserving pulpal health and mitigating the risk of nerve death.
Tip 1: Practice Meticulous Oral Hygiene: Consistent and thorough oral hygiene practices, including regular brushing and flossing, are essential for preventing dental caries, a primary cause of pulpal inflammation and necrosis. Effective plaque control minimizes bacterial exposure and reduces the risk of pulpal involvement.
Tip 2: Seek Prompt Treatment for Dental Caries: Early detection and treatment of dental caries are crucial for preventing pulpal inflammation and necrosis. Small cavities can be addressed with conservative restorations, while delaying treatment allows the caries to progress and potentially expose the pulp.
Tip 3: Utilize Protective Measures During Sports: Participation in contact sports increases the risk of dental trauma, a significant cause of pulpal necrosis. Wearing a properly fitted mouthguard during athletic activities can significantly reduce the severity of dental injuries and protect the pulp from damage.
Tip 4: Exercise Caution with Teeth Whitening: While teeth whitening can improve aesthetics, excessive or improper use of whitening products can irritate the pulp and potentially lead to inflammation. Follow the dentist’s instructions carefully and avoid overusing whitening agents.
Tip 5: Manage Systemic Health Conditions: Systemic diseases, such as diabetes and cardiovascular disease, can compromise pulpal blood supply and increase the risk of necrosis. Effectively managing these conditions through medication and lifestyle modifications can improve pulpal health and reduce the likelihood of nerve death.
Tip 6: Undergo Regular Dental Examinations: Routine dental check-ups allow for early detection of dental caries, periodontal disease, and other conditions that can impact pulpal health. Radiographic examinations can identify asymptomatic problems, such as periapical lesions, before they cause irreversible damage.
Tip 7: Be Aware of Bruxism and Clenching Habits: Chronic teeth grinding or clenching (bruxism) can generate excessive forces on the teeth, potentially leading to pulpal inflammation and nerve damage. Managing bruxism with a nightguard can reduce these forces and protect the pulp.
By adhering to these guidelines, individuals can proactively protect their pulpal health, minimize the risk of necrosis, and preserve their natural teeth.
