Yes, teeth whitening is a safe cosmetic dentistry procedure when performed by a qualified and experienced dentist. When used as directed, the bleaching agents in teeth whitening may not harm your teeth or gums. However, it is essential to note that some people may experience temporary side effects such as sensitivity or gum irritation after whitening their teeth. If you experience any of these side effects, be sure to contact your dentist so that they can make the necessary adjustments to your treatment plan.
