Preparing For Teeth Whitening In The Dental Office

Preparing for teeth whitening in the dental office implies: performing prophylactic cleaning of teeth, the process by which plaque and leftovers are removed, making a dental examination to determine if the patient is experiencing a high degree of dental decay, cracks and gum disease.

Teeth Whitening In The Dental Office

Although details of this procedure may vary, most often the dentist will follow the standard steps. This steps do not involve pain or discomfort of any kind, as follows:

  • Your dentist will introduce a cheek retractor to expose the aesthetics of the teeth;
  • A special resin substance will be applied on the gums to prevent irritation;
  • On the surface of teeth, the dentist will apply a solution based on hydrogen peroxide that will be left on for 15-30 minutes. After this period the gel is removed and if needed another layer of gel will be applied which in turn will be left on for another 15-30 minutes;
  • In certain situations, your dental doctor may use a special light source to potentate the bleaching agent effect. During this process, your doctor will check how your teeth respond to treatment;
  • After removing the last layer of gel, your dentist will examine the outcome of the treatment. Teeth can be whitened by 2-3 shades and in the best case, even with 8 shades.
