Average cost to whiten teeth

Teeth-whitening cost depends on the method, number of visits, peroxide system, tray design, dental examination, and existing restorations.

Whitening uses peroxide to alter colour molecules in natural enamel and dentine. It does not lighten crowns, veneers, fillings, or bonding, and untreated decay or gum disease should be addressed before cosmetic treatment.

Ask for a written comparison of in-office whitening, dentist-made home trays, and regulated take-home products. Confirm the concentration, fitting process, expected sensitivity plan, and what happens if the shade is uneven.

Have a dental examination before whitening if teeth hurt, gums bleed, a filling is broken, or one tooth has changed colour. Pain during treatment should be reported instead of covered with more gel.

Ask which stains can respond, whether restorations will need replacement for colour matching, and which method suits your enamel and gums. Ask for the complete treatment scope rather than an unexplained average.
