side effects and limitations of tooth whitening

The most common side effect experienced by user of teeth whitening techniques can be tooth sensitivity and or gum irritation.
While this can occasionally happen, most people find that the problem settles down, as tooth sensitivity is usually just a passing sensation when people first start using teeth bleaching and as your teeth get used to the process it stops occurring.
Gum sensitivity on the other hand can be because too much gel is used. Care must be taken not to over fill the bleaching trays, as when worn over the teeth the gel can ooze out on to the gums causing irritation. The gel is only for use on the teeth not the gums.
Another cause could be ill fitting bleaching trays. Care should be taken when molding the trays to your teeth. If any part of the tray overlaps the gums, trim the trays down to teeth level so that the gel does not contact the gums. This can be done easily with a pair if scissors.

You may get white patches on the teeth. These problems will go away after a few days.
If any of the above problems have been experienced, don’t worry they can be reduced by shortening the time that you spend on a session of teeth bleaching slightly.
You can also limit the frequency that you use teeth whitening for a while until the sensitivity goes away.
You will soon find the optimum time and frequency that suits you to use teeth whitening.
Whether you do it fast or more slowly the results are the same in the end.
If the teeth sensitivity is a problem, using a tooth paste specially formulated for sensitive teeth when brushing your teeth could be a very sensible solution.
Limitations

These will not respond to teeth whitening treatment. If you want to go ahead with the treatment then you will have to have the crowns, veneers and composite fillings replaced, otherwise you will finish up with teeth of different colours.

Gum Disease, Cavities, or Worn Tooth Enamel If you have any of the above, teeth whitening bleach may not be effective.

The processes are not recommended for anyone under the age of sixteen on medical grounds.
Pregnancy
Treatment is not recommended for pregnant or breast feeding mothers. Ingesting even very small amounts of the product can be harmful to a foetus.
