Teeth whitening is a cosmetic dental procedure that involves removing stains and discoloration from the surface of the teeth to improve their appearance. Teeth can become discolored due to a variety of factors, including aging, genetics, smoking, and consuming certain foods and beverages.

 There are two main types of teeth whitening procedures: in-office whitening and at-home whitening. In-office whitening is performed by a dentist and involves applying a strong bleaching agent to the teeth, which is activated by a special light. The procedure typically takes one to two hours and can result in significant whitening of the teeth.

 At-home whitening involves using a custom-fitted tray that is filled with a weaker bleaching agent and worn for several hours a day for a period of several weeks. While the results may not be as dramatic as in-office whitening, at-home whitening can still produce noticeable improvement in the appearance of the teeth.

 Teeth whitening is generally safe, but there are some potential risks and side effects, including tooth sensitivity, gum irritation, and uneven whitening. Patients should discuss their goals and concerns with a qualified dentist to determine the best approach for their specific needs.

 It is important to note that teeth whitening is a cosmetic procedure and is not a substitute for good oral hygiene habits, such as regular brushing and flossing. Patients should also avoid consuming foods and beverages that can stain the teeth, such as coffee, tea, and red wine, to maintain their results over time.
