There are two main types of teeth whitening:
* Over-the-counter (OTC) teeth whiteners: These products are available without a prescription and can be used at home. They typically contain a lower concentration of bleaching agent than professional teeth whiteners.
* Professional teeth whiteners: These products are only available through a dentist or other dental professional. They typically contain a higher concentration of bleaching agent and can provide more dramatic results.
How do teeth whiteners work?
Teeth whiteners work by breaking down the pigmented molecules in the teeth. These molecules are called chromogens. When they are broken down, the teeth become lighter in color.
The most common bleaching agent used in teeth whiteners is hydrogen peroxide. Hydrogen peroxide breaks down chromogens into water and oxygen molecules. These molecules are then excreted from the body.
What are the benefits of teeth whitening?
