Tooth Whitening

What is it?

Like hair and skin, teeth vary in colour. Some are yellower or darker than others, even when they are quite healthy.  Teeth tend to get darker as people get older.

Teeth sometimes become darker if their roots have been damaged or diseased and the 'nerve' has 'died'. Tooth colour can be very effectively lightened with Hydogen Peroxide (bleach), used on either the outside or the inside of the tooth.

Tooth bleaching is safe as long as the bleach does not touch your gums and burn them. Dentists use a special jelly bleach.  Tooth bleaching is not permanent and may need to be repeated from time to time.  The treatment works on tooth enamel, but does not whiten any crowns or fillings you might have.

What will my dentist do?

Where the 'nerve' of a tooth has 'died' (through damage or disease) and the tooth's root has been filled, bleach is put inside the tooth, under a removable tray or temporary dressing.  This can take from a few days to a week.

There two ways of bleaching the outside of teeth. One takes place at home and the other in the dentist's surgery.

At home bleaching

  • The dentist will give you 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 put the tray in your mouth overnight (for a few hours) on several occasions, as instructed by your dentist (probably over a period of weeks).

  • The dentist will need to use a putty-like material to make moulds of your mouth (called 'impressions'), so a dental technician can make the tray to fit. At your next appointment, your dentist will check that the tray fits and show you how to put the bleach in the tray at home.

In surgery bleaching​

  • Your dentist (or dental care professional) will use a stronger bleach jelly than is used for home bleaching. Dentists use this method to bleach all the teeth at the same time in either your upper or lower jaw. The strong bleach will touch the teeth for less time than with home bleaching.

  • The dentist should protect your gums. They will paint the bleach onto the teeth and either shine a special light at them or just leave the bleach on the teeth for some time.

  • The bleach is then washed off with water.

For both techniques, your dentist will make a note of your teeth colour using model teeth in different shades before they treat you. Look at the colour match yourself before the treatment, so you can compare it with the colour after bleaching. Occasionally bleaching can cause your teeth to be more sensitive to hot, cold and sweet things. Should this occur, stop bleaching for a night or two if you are using the nightguard bleach, and use desensitising toothpaste. If the problems persist, see  your dentist.

Over-bleaching can also lead to sensitivity or loss of vitality (where the tooth dies) which is why it is essential for the procedure to be carried out by a trained dental professional.

What are the benefits?

Bleaching improves the appearance of your teeth without removing any of the natural tooth surface. Bleaching is a better option than a crown or veneer if you want to lighten the colour of healthy teeth, as the placing of crowns and veneers involves changing the shape of the tooth.
