Tooth whitening policy

Tooth whitening can be a highly effective way of lightening the colour of the natural teeth without removing any of the tooth surfaces.  It does not work on dentures, crowns, white fillings or bridges. 
The active ingredient in tooth whitening products is usually hydrogen peroxide or carbamide peroxide.  As this active ingredient is broken down oxygen gets into the enamel on the teeth and the tooth colour is made lighter.
In accordance with EU law, over the counter home whitening kits in the UK contain too little hydrogen peroxide (0.1%) to noticeably lighten the teeth.  The legal limit for a dentist to use is between 0.1% and 6% hydrogen peroxide.  These higher percentage products used by a dental professional will produce a safe, effective and long-lasting tooth lightening result.
The first treatment should be carried out by the dentist (or hygienist or therapist on the instruction of the dentist), after this the patient can continue the treatment at home....
