What is Teeth Whitening?

Teeth whitening is a cosmetic procedure that involves using products, such as teeth whitening strips, gels, pastes, and even laser treatments, to get your teeth brighter and whiter. The process involves removing stains, discoloration, and other types of dental discoloration that make the teeth look dull and yellow.

The Factors Involved in Tooth Discoloration

The time that it takes for teeth to whiten varies depending on factors such as:

  • The severity of the staining. The cause of staining and how long it has been on the teeth.
  • The type of discoloration. Teeth whitening is most effective on extrinsic stains that affect the outer layer of teeth. Intrinsic discoloration that affects the dentin may require other teeth whitening procedures.
  • The method of whitening used. Certain teeth whitening products, such as teeth whitening strips, may take longer to work compared to other methods, such as laser treatments.
  • The frequency of use. Regular use of teeth whitening products may produce faster results compared to occasional use.
