Teeth whitening/ Bleaching : Most Commonly Performed Cosmetic Treatment

Tooth whitening is a procedure in which your dentist lightens your teeth and removes any stains and discolourations. However this is not a permanent procedure, it has to be repeated to maintain a brighter and whiter smile.

Why do my teeth discolour?

The outermost layer of your tooth that is enamel and its underlying layer called dentine together reflects the colour of your tooth. These layers are porous and hence pick up stains from various agents like tobacco chewing or smoking, drinking tea, coffee and other coloured drinks.

Aging also causes the teeth to discolour. There are some stains known as intrinsic stains that are deposited inside tooth from the blood itself. This can happen if you are exposed to high amount of fluoride which gets deposited in bones and teeth. Certain medications like antibiotic tetracycline was taken by mother during pregnancy, it gets deposited in her child's teeth causing them to discolour. These type of stains cannot be treated by bleaching , but we option of veneering for such teeth.

What are the precautions or points to remember about bleaching?

  • You need to get all fillings done before bleaching if you have cavities as these chemicals can seep in cavities and reach nerve tissues as well.
  • If you have receding gums then the part of roots of teeth will be exposed which cannot be whitened by this procedure.
  • Whitening works only on tooth enamel, so it won’t work on fillings, ceramic crowns, dentures, bridges or veneers.
  • Any root canal treated tooth or dead tooth requires different type of bleaching procedure called as non vital bleaching as this tooth is stained from inside and not from outside.
  • If you are pregnant you need to postpone the procedure till delivery.
  • You might need another session after 6-12 moths.
