Teeth whitening treatment starts with a cleaning of the teeth's surface. The dentist will eliminate any visible plaque, and food debris stuck between teeth. Hydrogen peroxide or carbamide peroxide are bleaching agents that will then be applied to the teeth and removes stains and discoloration. Patients can expect to see noticeable results following the treatment, but it may take a few teeth whitening sessions to achieve the patient's ideal results. While teeth whitening at home has risen in popularity over the years, we'd still recommend our patients to have their teeth whitening treatments done in-house by a qualified professional.
