The recommended duration for adhering whitening strips to the teeth varies depending on the specific brand and formulation of the product. Generally, these strips are designed to be applied for a period ranging from 5 minutes to 2 hours, with the manufacturer’s instructions providing the definitive guidance. For example, some strips may require 30 minutes of application once a day, while others are designed for longer durations but used less frequently.
Adhering to the specified application time is crucial for maximizing the effectiveness of the whitening treatment and minimizing potential side effects, such as tooth sensitivity or gum irritation. Overexposure can lead to increased sensitivity and enamel damage, while insufficient application may not yield the desired whitening results. The concentration of the active whitening agent, typically hydrogen peroxide or carbamide peroxide, is a key factor in determining the appropriate contact time.
