If you opt to continue your treatments at home, your dentist can craft personalised bleaching trays based on impressions of your teeth and draw up a plan for how often these trays must be worn over a period of time to whiten your teeth. Depending on the sensitivity of your teeth, the dentist may also vary the concentration levels of the gel. It is important to follow the correct methods and techniques recommended by your dentist as this will further contribute to a comfortable and more successful outcome. For sensitive teeth, your dentist may suggest longer intervals between applications and pre-treatment desensitising. Post-treatment methods may include the use of special gels of toothpastes.
