Teeth often become darker as age, due to changes in their mineral structure. Teeth can also become stained by bacterial pigments, drinking dark colored liquids like coffee, tea and red wine, and smoking. Certain antibiotic medications can cause teeth stains or a reduction in the brilliance of the enamel, as well.

GriDents cosmetic dentistry team are experts at dental bleaching, also known as teeth whitening.

 What means teeth whitening (Bleaching)?

Teeth whitening is the procedure of lightening and removing the stains and discoloration. It is one of the most popular cosmetic dental procedures. The appearance of the teeth is improved and it is cheaper than the other techniques and less inconvenience than other techniques.

Every day, a thin coating is formed on the tooth and it picks up stains. Also the enamel contains pores that contain stains. In order to maintain the brighter color the whitening should be repeated periodically because it is not a one-time solution.

What cause the darkness on the teeth?

Aging, tobacco, tea and coffee are the most common reasons for yellowing or stained teeth. They can stain the surface of the teeth. There can be stains inside the tooth and they are called as intrinsic stains. Exposure of too much fluoride as a child while the teeth are developing can cause the intrinsic stains. The tetracycline antibiotics, which are taken during the second half of pregnancy or given to the children 8 years or younger when the teeth are still developing, can cause intrinsic stains. For improving the appearance of teeth that have intrinsic stains tooth whitening can be a solution.

For the stains that are found on the surface, caused by age, foods or drinks the tooth whitening is most effective.


The whitening does not work on crowns or veneers and also it does not work on exposed tooth roots because the roots do not have an enamel layer.

Whitening can be done in dental office or at home. It is preferred to do the whitening in office by our clinic because the in-office whitening, which is also called as chairside whitening, allows the dentist to supervise the process and the progress more closely. The dentist can take photographs of the teeth so he/she can see how the treatment is progressing. One to two visits can be needed to take result from the whitening and each visit takes approximately 60 minutes.

When the examination is complete, the dentist will clean your teeth. Once this is completed, the whitening procedure begins.


There are no serious side effects of whitening but some people’s teeth may become more sensitive temporarily and there may be mild gum irritation.

The effect of the whitening materials on the development of the fetus is not known so the whitening procedures should not be done while a woman is pregnant. In this case the whitening procedure should be postponed since it is a cosmetic procedure.
