Teeth Whitening

Important note:

The legislation on tooth whitening in the UK changed on 31st Octobr 2012. Dental practices in the UK are no longer permitted to use whitening products containiing more than 6% hydrogen peroxide (equivalent to approximately 18% carbamide peroxide) for dental whitening for cosmetic purposes.

The position statements of the General Dental Council and Dental Protection UK can be read on the linked pdf documents on this page.


Teeth can be whitened predictably and safely at home using a number of different systems.

Tooth whitening can benefit almost anyone with healthy teeth who would like a whiter, healthier looking smile. Teeth naturally yellow and discolour over the years but staining is made worse by such things as smoking, tea, coffee and red wine. Whitening removes the integral discolouration of the teeth without damaging them leaving your teeth brighter but still natural looking.

Whitening of single, severely discoloured teeth where nerves have died and the tooth has been root filled can also be carried out using more advanced techniques.


If whitening is to be carried out, it is important that it is completed at least six weeks prior to the (re)placements of any crowns or veneers. Whitening will dehydrate teeth leading to a slightly white frosty effect that will diminish as the teeth rehydrate over a period of weeks following cessation of the whitening.

It is only after six weeks or more that any final shape matching for crowns or veneers should be carried out.
