What Determines the Cost of Teeth Whitening

The cost of teeth whitening varies depending on the method used and the current condition of the teeth. The dentist first examines the patient, then determines the scope of treatment based on the number of sessions and duration required.

Habits such as drinking tea and coffee, smoking, and teeth clenching can cause yellowing. Hormonal factors related to bone structure or chronic illnesses can also lead to discoloration and staining. The method and materials used directly determine the duration and scope of the procedure.

Whitening methods generally fall into two categories: home-type and office-type. In the home-type approach, impressions are taken to create custom clear trays; the patient then applies a dentist-prescribed amount of gel to the trays and uses them regularly at home. Using more gel than recommended, or without consulting a dentist, can damage tooth enamel.

Office-type whitening begins with a gum examination and, if needed, tartar removal; the gums are then covered with a protective barrier before the whitening gel is applied to the teeth. Some gels are activated with laser. The procedure may take one or several sessions depending on the patient's needs.

Application may differ for teeth that have undergone root canal treatment, and the materials used depend on the tooth's structure. The procedure can be performed on anyone over 18, though the maximum achievable whiteness varies by individual based on bone structure. Regular aftercare helps extend how long the results last.
