Whitening refers to the techniques aimed at the restoration of the natural colour of darkened/discoloured teeth and is classified into cosmetic dentistry. The approach differs for vital and non-vital teeth. Our dental surgeon will advise you on the best solution, which will depend on your teeth’s health, their vitality, your budget and time constraints. Whitening your smile will be one of the least expensive and least invasive ways to enhance your appearance and will be the first thing others will notice about you!

Teeth darken principally because of stains which can be classified as:

  • Extrinsic: tobacco, dietary tea and coffee, chlorhexidine.
  • Intrinsic: trauma, hypocalcification, tetracycline, other systemic causes.
  • Aged related: secondary dentine formation.

Most products are based on hydrogen peroxide or carbamide peroxide which acts as the bleaching agents. The latter will diffuse through the porous enamel and oxidise the larger chromagens into smaller ones which reflect light less.

At Best Dental Co Ltd, the premium whitening products most commonly used are Opalescence Tooth Whitening System.

Customized Opalescence Take-Home System

  • Before the start of your whitening treatment, a scaling is conducted in order to remove all dental plaque, calculus and stains which are hindrances.
  • Following that, the shade of your teeth is checked, allergies to products noted and you will be informed about the restoration of existing fillings.
  • Your impressions are then taken by our dental surgeon in order to create a customised tray that will fit your mouth perfectly and comfortably. In addition, you will be given syringes of Opalescence gel that contain prescription strength formulations which you will have to place in the tray.
  • The tray has to be used 2-3 hours daily and chromogenic food/drink should be avoided for 2 hours post-treatment.
  • A routine follow-up should be conducted to make sure everything is running on smoothly. The treatment generally lasts between 2-3 weeks.

The bleaching products are chemically very active and may cause sensitive teeth. This is controlled as much as possible by adjusting the concentration of the bleaching agent and length of exposure. Desensitizing toothpaste and fluoride mouthwash can be used topically for relief.
