Prolonged exposure to the bleaching agents in dental whitening strips beyond the recommended time can lead to several adverse effects. The active ingredients, typically hydrogen peroxide or carbamide peroxide, can dehydrate the tooth enamel. An example of this is experiencing increased tooth sensitivity after exceeding the suggested application duration.
Understanding the potential consequences of overuse is essential for maintaining oral health during whitening treatments. Following product instructions mitigates the risk of enamel damage, gum irritation, and heightened tooth sensitivity. Historically, the development and refinement of whitening strips have aimed to balance effectiveness with minimizing these side effects.
