tooth whitening is a cosmetic dental procedure that involves the use of bleaching agents to remove stains and discolorations from teeth and improve their overall appearance. There are different methods of tooth whitening, including in-office whitening, home whitening kits, and over-the-counter whitening products. In-office whitening provides immediate results, while home whitening kits are more convenient but may take longer to achieve the desired level of whitening. Over-the-counter products are also available, but may not be as effective as professional whitening treatments. It is important to consult with a dentist to determine if tooth whitening is appropriate for you and to discuss potential risks and outcomes.
