Tooth Whitening

What is tooth whitening?

Tooth whitening can be a very effective way of lightening the natural colour of your teeth without removing any of the tooth surface. It cannot make a complete colour change, but it may lighten the existing shade.

Whitening is a process where the tooth discolouration is ‘whitened’ to a lighter shade. The stains are removed using chemicals, which is a safe procedure when carried out under professional supervision. Treatment results usually depend on the severity of the discolouration. Both vital (i.e. live) and non-vital teeth can be bleached and may take several visits to complete. It is not effective on dental restorations such as amalgam fillings, metal or porcelain crowns, etc.

Why do teeth stain?

As we get older teeth may discolour, but also they can become stained because of food and drinks, such as tea, coffee and red wine. Smoking is also a factor in teeth staining.

Tartar can also affect the colour of your teeth, and sometimes tiny cracks in the teeth become more prone to staining.

After consultation, the dentist will be ale to tell you if you are suitable for treatment, based on your oral condition. At this time the cause and nature of your tooth discolouration will be assessed, to that the best method for whitening can be established.


What methods do you use?

During your consultation, we will provide you with more information on the various types of whitening procedures available and the duration and frequency of the treatment.

At St Cuthbert’s we generally use two methods of whitening:

  • In surgery whitening
  • Home whitening

The most dramatic results are achieved by combining both of these methods.

The brands we use are:

What does the procedure involve?

A rubber shield or a gel will be put on your gums to protect them. The whitening product will then be applied to your teeth, using a specially made tray which fits into your mouth like a mouth guard.

The ‘active ingredient’ in the whitening product is usually hydrogen peroxide or carbamide peroxide. As the active ingredient is broken down, oxygen gets into the enamel on the teeth and the tooth colour is made lighter.

How long does the whitening last?

The effects of whitening can last up to three years. However, this will vary from person to person. The effect is less likely to last as long if you smoke, or eat or drink products that can stain your teeth.

Please get in touch today to book in for an initial appointment so your dentist can discuss the options available to you and suggest which treatment will be best for you.

You can also complete a free no obligation Smile Analysis questionnaire.
