Professional teeth whitening is a dental procedure that lightens the color of your teeth. It can be done in the dentist's office or at home with a kit provided by your dentist. There are two main types of teeth whitening: laser teeth whitening and chemical teeth whitening. Laser teeth whitening uses a laser to activate a bleaching agent that is applied to your teeth. Chemical teeth whitening uses a bleaching gel that is applied to your teeth and then activated with a light or heat source.
Teeth whitening can be an effective way to improve the appearance of your smile. It can remove stains and discoloration caused by coffee, tea, red wine, and smoking. Teeth whitening can also help to lighten the color of your teeth if they have become yellowed or darkened over time. In some cases, teeth whitening can even be used to correct minor tooth defects, such as chips and cracks.
