Following a fluoride treatment, a period of abstaining from food and drink is generally recommended. This waiting period allows the fluoride to effectively absorb into the tooth enamel, maximizing its protective benefits. The duration may vary slightly depending on the specific fluoride application, such as varnish, gel, or foam.
The rationale behind delaying consumption is to prevent the fluoride from being washed away or diluted before it has had sufficient time to interact with the teeth. Optimal fluoride uptake strengthens enamel, enhancing its resistance to acid attacks caused by bacteria and sugars. This process contributes to a significant reduction in the incidence of dental cavities and reinforces long-term oral health. Fluoride treatments have been a cornerstone of preventative dentistry for decades, with a proven track record of efficacy in protecting against tooth decay.
