In-office whitening is one of the fastest ways to brighten your smile. The procedure typically takes about one hour and is performed at our dental clinic.
During treatment, the lips and gums are protected while a professional whitening gel is applied to the teeth. The whitening gel typically contains medical-grade hydrogen peroxide, a clinically proven whitening agent used in professional dental whitening treatments.The gel may be activated with a specialized light to enhance the whitening effect.
Many patients notice their teeth becoming up to 8 shades lighter after a single appointment, depending on the type and severity of staining.
Take-home whitening systems use custom trays created from impressions of your teeth.
These trays hold professional whitening gel evenly against the enamel, helping achieve consistent results. Patients typically use the trays for one to two weeks depending on the desired level of whitening.
This option allows patients to whiten their teeth gradually at home under dentist supervision.
