Teeth Bleaching & Teeth whitening
The outer layer of a tooth is called enamel. We all have different shades of tooth enamel originally. That is genetically and some teeth can be affected during their development for example due to a trauma or medical treatment.
However the most common problem is the discoloration we get with time, due to all that we expose them for. Smoking, food and beverages are the normal reason for discoloration. A dental cleaning can remove plaque and dental stone but some of the discoloration penetrates the enamel. This you cannot remove with cleaning. Since late 1980s, dentistry started to use bleaching as an option to regain a satisfying color of the teeth.
Bleaching methods use carbamide peroxide which reacts with water to form hydrogen peroxide. The peroxide oxidizing agent penetrates the porosities in the rod-like crystal structure of enamel and breaks down stain deposits in the dentin. All natural teeth can be bleached but the result depends on cause of the discoloration and also the intake of colorful food and beverages afterwards.
At TandCity we offer the possibilities of bleaching at home:
Three visits are required. On the first visit we take impressions of the teeth you wish to bleach and give you topical information. On the second visit you get the bleaching tray/s, bleaching gel and instructions how to bleach. We take clinical photos of your teeth and determine the color they have. You then start the treatment at home whenever you are ready. It often takes between one or two weeks to reach a satisfying shade. During the bleaching your teeth can be a little sensitive which can be treated with fluoride. On the third visit we control the treatment and take new photos. The result lasts between six month and two years, all depending on what your teeth have been exposed to. The only thing to do when it is time for a new treatment is to buy new bleaching gel, the trays you already have.
