What does tooth whitening do?

Tooth whitening can be a highly effective, yet very simple way, of lightening the colour of teeth without removing any of the tooth surface. It cannot make a colour change, but lightens the existing colour.

What does the procedure involve?

The dentist applies a chemical barrier to the gums, which will protect them during the whitening process. The whitening solution is then applied to the teeth and the chemical is then activated using heat, or heat and light combined.
Once the whitening process is finished the barrier will be easily removed in one piece.

If the tooth has been root treated, the canal, which previously contained the nerve, may be reopened and the whitening product is put in.


What does the procedure involve?

The active ingredient in the product is normally hydrogen peroxide or carbamide peroxide. If the tooth has been root treated, the canal, which previously contained the nerve, may be reopened and the whitening product is put in. In both cases, the procedure needs to be repeated until the right shade is reached.

How long does the procedure take?

First of all you will need 2 or 3 visits to your dentist. Your dentist will need to make a mouthguard and will need to take impressions for this at the first appointment. Once your dentist has started the treatment, you will have to continue the treatment at home. This will mean applying the bleach regularly over 2-4 weeks for 30 minutes to 1 hour at a time.
