Did You Know? 5 Interesting Facts About Teeth Whitening.

Whitening your teeth is a form of cosmetic dentistry that offers immediate results. Tooth whitening has been in fashion for much longer than you may expect, as there is historical evidence of the ancient Egyptians using rudimentary teeth whitening practices nearly 4,000 years ago. The type of bleaching practices they used then would have included filing the teeth, using a mix of vinegar and pumice stone, and the use of ammonia. Nowadays, we use hydrogen peroxide for the whitening of the teeth and there are options for whitening available both over the counter for anyone to use at home, as well as professional whitenings done by dentists. Tooth whitening is a great way to get an instantly refreshed smile. Here are some facts about teeth whitening you may not know.

5 Facts About Teeth Whitening

  1. Teeth are porous. Although you can’t see it with the naked eye, teeth actually have microscopic holes in them and those pores are what lead to discolouration as they become stained from food and beverages. During tooth whitening, these pores open slightly so that stains can be removed. After the whitening, the teeth remineralize and the pores become smaller so they do not immediately stain again.
  2. Teeth Whitening Was Accidentally Discovered. Teeth whitening uses hydrogen peroxide, but whitening was not the original goal of the use of peroxide. It was actually used as a part of mouthwash in hopes of reducing gum disease. Through the course of repeated use, it was discovered that teeth were being whitened in the process and thus tooth whitening was invented.
  3. Teeth Must Be Whitened By Qualified Personnel. Over the counter whiteners can be used by yourself, but the whiteners used by dentists and dental hygienists are stronger and require professional use. Having a professional handle the stronger tooth whitening chemicals keeps you safe and ensures a proper job of even whitening while also making sure you have a professional there in case anything needs treatment. A dentist will also be able to identify any potential problems before the bleaching commences, so you can have a safe, comfortable experience and get the results you desire.
  4. Custom Fitted Trays Are Critical. There are over the counter whitening products you can use, but since they are not fitted to your mouth they may whiten unevenly, leaving the contours of your teeth a different colour. These products that are not custom fitted can also cause pain, discomfort, and damage, as the whitening gel may leak out of the side and onto the gums causing burning in the mouth. When you get your teeth professionally whitened, there is little chance of discomfort and the entirety of your teeth will be evenly whitened.
  5. Only Natural Teeth Change Colour. If you have crowns or veneers that are matched to your current tooth colour, they will not change colour when you whiten your teeth. This will leave your natural teeth a different shade than any veneers, crowns, or otherwise non-natural teeth. If you have non-natural teeth and plan on whitening your teeth, discuss with your dental hygienist or dentist and ask if they have any alternative suggestions.

Q: How long does tooth whitening last?
A: That will depend on your personal lifestyle, specifically the foods you eat. If you get your teeth whitened and then drink coffee and citrus juice all day, your teeth will likely become discoloured after a month. Those who avoid tooth damaging foods will get a much longer result.

Q: Why are my teeth yellowing?
A: There are a number of reasons your teeth may have lost the pearly white shine that they used to have:

  • Beverage consumption such as coffee, red wine, black tea, or cola
  • Smoking
  • Eating certain acidic or dark coloured foods 
  • Natural aging process

Q: Is tooth whitening bad for your teeth?
A: No, getting your teeth professionally whitened does not damage the enamel.
