Teeth whitening is a dental procedure that lightens the color of your teeth. It can be done in the office or at home, and there are a variety of methods that can be used. One common method is to use a bleaching agent, which is applied to the teeth and then activated with a light or laser. Another method is to use a whitening toothpaste or gel, which contains a lower concentration of bleaching agent and is used over a longer period of time.
Teeth whitening can be an effective way to improve the appearance of your smile. It can remove stains from coffee, tea, wine, and other foods and drinks. It can also help to lighten the color of teeth that have yellowed with age. Teeth whitening is a safe procedure, but it can cause some side effects, such as tooth sensitivity and gum irritation. These side effects are usually temporary and will go away within a few days.
