How Does Teeth Whitening Work?
Professional teeth whitening works through a chemical process called oxidation. Whitening products use bleaching agents, such as hydrogen peroxide or carbamide peroxide, to break down colored molecules responsible for tooth discoloration.
The Science
Active Ingredients: Professional teeth whitening products typically use hydrogen peroxide or carbamide peroxide to lighten tooth discoloration.
Oxidation: The peroxide diffuses through the enamel and dentin, reaching discolored molecules within the tooth.
Breakdown of Stains: Reactive oxygen molecules interact with colored compounds, changing their chemical structure and making them less visible. This helps the teeth appear whiter and brighter.
Types of Stains
Teeth can become discolored for a number of reasons, including dietary habits, aging, medication, and genetics. The success of teeth whitening depends partly on the type and cause of the discoloration.
Extrinsic Stains: These stains develop on the outer surface of the teeth and are commonly caused by smoking, coffee, tea, and dark sodas. Many extrinsic stains respond well to professional whitening treatments.
Intrinsic Stains: These stains develop within the tooth and may result from aging, dental trauma, or certain medications. Intrinsic discoloration can be more difficult to treat, and some types may not respond well to traditional whitening treatments.
Why Professional Teeth Whitening is Preferable
Professional teeth whitening offers the benefit of dental supervision and customized treatment. Your dentist can evaluate your teeth, recommend an appropriate whitening method, and help manage potential sensitivity or gum irritation.
Professional treatments can also provide more noticeable results in a shorter period than many over-the-counter products. However, dentist-supervised take-home whitening options can also be effective.
