The Effect of Too Much Dental Bleach

Tagged Under : ,

Dental bleaching is the solution for people who have discolored teeth. There are two ways to improve the color of the teeth. One is through bleaching and the other one is through whitening. Bleaching is done to make teeth whiter, further than its natural color. There are some bleaching products, such as hydrogen peroxide and carbamide peroxide, available. Whitening is done when one is  re-establishing the color of the tooth’s surface. In this method, tooth’s dirt and debris are removed. Toothpaste and any cleaning products are considered whiteners. There is another form of bleaching available in the market today-Laser Bleaching. It uses light energy to speed up the process of dental bleaching.  


The procedures in whitening teeth are safe, as long as it is done in accordance to the doctor’s advice. But there are still risks in doing so.

Hot Teeth Whitening Topic
  1. When higher concentration bleach is used, a person is more likely to experience sensitive tooth. Increased sensitivity to temperature, pressure and touch are the ones bleaching can cause. People who went through gum recession and faulty restoration resulting to cracks in the tooth or leakage are also prone to sensitive tooth. 
  2. Gum irritation is one of the more likely effects of dental bleaching. This is because of the peroxide whiteners used in the procedure. Majority of dentists recommend the use of peroxide whiteners in tooth bleaching. Its whitening component and quick depletion into the mouth are amongst the reason why it is effective and is safe to use. But still, gum irritation may still occur especially during instances of higher concentration. Irritation may subside after few days.
  3. Although bleaching can make teeth whiter, there are some teeth which color could not be improved. These are those which went through restoration (e.g. bonding, dental crowns and porcelain veneers). So bleaching may result to an uneven color of the teeth, which isn’t favorable to the patient.


 In addition to the possible risks listed, there are other information the would-be takers of the bleaching procedure must know.

  1. That, bleaching has nothing to do with the deterioration of the teeth’s strength. The result of the teeth whitening is noticeable approximately after two weeks.
  2. The effect of the procedure is more likely on how it will affect the sensitivity of the teeth. The bleaching procedure and the DFA-approved products used, doesn’t cause oral cancer and other kinds of severe condition.
  3. In order to keep the teeth white after bleaching, patients are advised to stop smoking and to avoid drinking dark colored liquids through straw.
  4. Moreover, there isn’t any identified effect of bleach solution, to the fetus/baby, being swallowed by preggies. But just the same, women are advised not to undergo this treatment yet while being pregnant.


With the information presented, it is safe to conclude that dental bleaching is generally not dangerous. It has minor consequences though if not done properly. The irritation, caused by bleaching, only takes a few days. Considering that it doesn’t trigger oral cancer, is one thing that majority of the population will want to hear about.
