Teeth Whitening

Teeth whitening is a cosmetic procedure that lightens the color of teeth to remove stains and discoloration. It can be done by a dentist or other regulated dental professional, or at home with over-the-counter products.
Method
Description
In-office
A dentist or other dental professional uses a variety of techniques and bleaching products to whiten teeth. They may take an impression of your teeth to make a custom mouthguard to apply a bleaching gel at home.
At-home
You can use custom-fitted trays or over-the-counter products like strips, gels, rinses, chewing gums, or paint-on films to apply a bleaching agent to your teeth. Some at-home kits use a heat lamp, blue light, or UV light to "radiate" the whitening paste.
Teeth whitening works by using chemicals like hydrogen peroxide or carbamide peroxide to break down chromogens, which are the compounds that cause tooth stains. The active ingredient in most whitening products is hydrogen peroxide, which is delivered as hydrogen peroxide or carbamide peroxide.
Some people experience tooth sensitivity from teeth whitening products, but it's usually temporary
