You must always be aware of what you are putting into your mouth and at least know beforehand what the potential dangers are. With so many teeth bleaching kits around that can be bought in any drugstore, it is up to the consumer to read and understand that the chemicals they are about to use to bleach their teeth are quite strong.

The side effects that are ever present when attempting to whiten your teeth include tooth sensitivity which may last long after the procedure has been completed and also gum damage or irritation. This could include some swelling making it difficult to eat and drink.

The active ingredient in these tooth whitening products is carbamide peroxide and it is usually contained within tooth whitening trays. The reason for the use of the tray is that it will direct the peroxide straight to the teeth while keeping it away from the gums.
