The colour of your teeth can be lightened with Carbamide Peroxide, used either on the outside or the inside of your tooth or teeth.
- Like hair and skin, teeth vary in colour. Some are yellower or darker than others, even when they are quite healthy.
- Teeth sometimes darken if their roots have been diseased. A change in colour is caused by blood from the root canal.
Whitening is completely safe as long as the whitening agent (bleach) does not touch your gums and burn them. A special jelly bleach will be used.
How teeth are whitened:
For a tooth which is dark inside, the bleach is put in the root canal temporarily, before or after the tooth is root-filled.
There are two ways of bleaching the outside of teeth.
- You may be given a weak bleach jelly to use at home in a tray which fits closely round your teeth. The tray makes sure that the jelly does not burn your gums. You will need to use the tray for an hour or two a day, for up to six weeks.
- A dental technician will make the tray you use for bleaching your teeth at home from an impression of your teeth. The fit of the tray will be checked and you will be shown how to fit it and put the jelly in at home.
- Another method is to use a stronger bleach jelly. Here all the teeth are whitened at the same time in either your upper or lower jaw. The stronger bleach will touch the teeth for less time than with the home bleaching.
If the stronger bleach is used your gums will be protected. Bleach will be painted on to the teeth and heated with a light for a few minutes. This is then washed off with water.
- A note will be made of your tooth colour using model teeth in different shades before you are treated. You may look at the colour match yourself before the treatment so you can compare it with the colour after bleaching.
- Your teeth may be sensitive to hot and cold food and drink for a few days after bleaching.
The benefits of this treatment:
This technique improves the appearance of your teeth without removing any of the natural tooth surface. This is a better option than a crown or veneer if you want to lighten the colour of healthy teeth.
