While teeth whitening is generally safe, some people may experience temporary tooth sensitivity or gum irritation. It's recommended to consult with a dentist before undergoing any teeth whitening treatment to ensure it is appropriate for your dental health and to discuss potential risks and benefits. Maintaining good oral hygiene practices, avoiding staining foods and drinks, and regular dental check-ups can help prolong the results of teeth whitening. It's also essential to follow the instructions provided by the dentist or product manufacturer for optimal and safe whitening outcomes.It's important to note that teeth whitening may not be suitable for everyone. Individuals with dental restorations such as crowns, veneers, or tooth-colored fillings may not experience the same whitening effects. In such cases, alternative cosmetic options can be discussed with a dental professional.
