Teeth whitening is a procedure that uses a bleaching agent to lighten the color of teeth. The bleaching agent is usually a peroxide-based gel applied to the teeth using a special tray or mouthpiece. It penetrates the enamel and dentin to break down the staining molecules, resulting in brighter teeth.
Many different types of stains can occur on teeth, including:
These types of stains are caused by abnormalities in the structure of teeth. Intrinsic stains can be caused by trauma to teeth, tooth decay, and certain types of medication. They can be difficult to remove with a general whitening treatment and may require a stronger bleaching agent.
These types of stains are caused by substances that come into contact with teeth, such as food and beverage items, tobacco products, and dental plaque. Extrinsic stains are the easiest type of stain to remove with teeth whitening and typically respond very well to treatment.
As the name implies, these stains are caused by the natural process of aging. Age-related stains typically occur on the teeth near the gum line and are usually treated using a stronger bleaching agent.
There are a few types of stains that a whitening treatment cannot correct. These include:
Tetracycline staining is caused by using antibiotics during childhood.
Fluorosis is a condition that causes teeth to become discolored due to too much fluoride exposure.
Veneer staining is typically permanent and cannot be corrected with teeth whitening.
