What is teeth whitening?
Over time, your teeth can go from white to not-so-bright for a number of reasons. Teeth whitening is a common procedure in cosmetic dentistry that will “whiten” your natural teeth to a lighter shade.
How does it work?
It works by increasing the tooth’s permeability to oxygen, which breaks down stain molecules, thus whitening your smile. It is a safe procedure when carried out under the supervision of your dentist.
Tray-home whitening works by applying low strength bleaching gel within specialised whitening trays. The dentist makes special custom fitted trays, which the patient wears either in the day or overnight.
No other method seems to deliver such favourable whitening results as tray home-whitening, while also preserving the enamel of the teeth.
The use of a low concentration gel in a custom fitting tray has been shown to be most versatile, safe, efficacious and cost effective way to whiten teeth.

Frequently asked questions
How safe is teeth whitening?
Tray home-whitening (using a low concentration bleaching gel) has the most research in the world for safety and efficacy. At Chalfont St Peter Dental Practice we only use high quality whitening gels at the safe concentration required, as set by the General Dental Council.
What if my teeth are sensitive?
All teeth whitening procedures will increase the risk of sensitivity during the whitening process. This is usually temporary and subsides up to 2 weeks after completing the procedure. At Chalfont St Peter Dental Practice we only use safe, low concentrations of whitening gel, therefore reducing the risk of sensitive teeth. Using a sensitive toothpaste 2 weeks prior to whitening can help reduce sensitivity.
How long do I have to wear the trays for?
Our gold-standard whitening gel should be used for 2-4 hours every night, over an average period of 2 weeks.
The low concentration whitening gel gradually activates over this time to gently whiten teeth. We find this works best for the majority of our patients, with a safe, reliable, enhanced whitening effect. (If impractical we can also offer a daytime gel, worn for 1-2 hours in the evening.)
For teeth with white spots, brown stains or nicotine staining, the average wear time can range between 6-8 weeks. Your dentist will be able to give you more information if this is the case.
How long does the whitening last?
Many factors play a part in how long teeth remain whitened. These include how often you drink tea, coffee, red wine, and also the type of discolouration to begin with. If teeth are whitened as per the dentists instructions, teeth whitening stability can last between 1-2 years.
What if I have a single dark tooth?
Single dark teeth first need to be assessed by the dentist to determine the cause of darkness. Your dentist will then advise you on the best method to whiten the tooth. These teeth can generally be whitened either by conventional tray home-whitening or by a procedure called internal whitening (which can take 1-6 visits).
