What Is Tooth Whitening?
Tooth whitening is a process that “bleaches” the teeth, removing it of stains on the enamel and dentin to affect a lightening of any discoloration present.
What Is Tooth Discoloration?
Tooth discoloration depends upon its many causes and it is important to distinguish between an external and internal stain.
External stains: tobacco, tea, coffee and juices like grape and apple, coffee,
tea and tobacco
Internal stains: excessive uoride (during teeth formation), aging, trauma, nerve degeneration, tetracycline (while teeth are forming)
Only professional whitening procedures such as the custom bleaching can remove both internal and external stains. Over-the-counter tooth whitening products like toothpastes only remove the external stains.
Who Can Undergo Tooth Whitening?
Anybody can benefit from a tooth whitening procedure. A certain procedure though may be less effective for some people. Patients whose teeth are stained by tetracycline may experience difficulty in achieving the desired whiteness. People with veneers, crowns or linings may also experience uneven whiteness because these dental fixtures do not whiten along with the rest of the teeth.
Can A Pregnant or Nursing Woman Bleach Her Teeth?
It is recommended and agreed that a pregnant woman and nursing mother should avoid any teeth whitening procedure. The reason for this is there’s no clinical studies done yet to pan out the effects of the bleaching agents to a woman’s health if she’s pregnant or nursing.
Why Are There Teeth That Do Not Whiten Evenly With The Rest?
The sides of your teeth and the biting edges whiten more quickly than the rest. This is so because of the thicker enamel in these areas. Teeth with thicker enamel respond faster to the bleaching agent than teeth with thinner enamel. Continue with your whitening procedure and the whiteness will even out eventually.
Is Tooth Whitening Safe?
The most preferred tooth whitening procedure is the custom bleaching.
There’s no danger of the bleaching agent harming your teeth and gums. It also does not damage the enamel or cause any tooth weakening. The only short term side-effect can be tooth sensitivity which goes away quickly when the process is stopped.
