What Happens During a Teeth Whitening Treatment?

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.

Teeth Whitening Can Correct Many Types of Stains

Many different types of stains can occur on teeth, including:

Intrinsic Stains

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.

Extrinsic Stains

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.

Age-Related Stains

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.

Which Stains Cannot be Whitened?

There are a few types of stains that a whitening treatment cannot correct. These include:

Tetracycline Staining

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

Veneer staining is typically permanent and cannot be corrected with teeth whitening.

Are There Teeth Whitening Alternatives?

If you are not eligible for teeth whitening or want to achieve a lighter shade than cannot be achieved with teeth whitening, there are other options available. These include:
