Professional teeth whitening services are typically offered as in-office or chairside treatments or as custom-fitted take-home kits. Professional teeth whitening products contain a higher concentration of bleaching agents, delivering better, brighter, and longer-lasting results in less time than over-the-counter products. Professional teeth whitening is also applied by a professional dentist for safer, more precise use and a reduced risk of side effects. The dentist can make sure that your teeth and gums are healthy enough for the whitening treatment and double check to make sure there aren’t any restorations like crowns, veneers, or bridges or deep stains or discolorations that won’t respond to the whitening.
