Frequently Asked Questions

What causes teeth to discolour?
Teeth naturally discolour with age and “yellowing” or “greying” is common as we get older, which is why whitening can make you look younger. Other common causes of tooth discolouration are drinks such as coffee, tea, red wine and foods such as beetroot, curries, red berries, and smoking. Some smokers use whitening as an incentive to stop smoking!

What is tooth whitening?
It is a cosmetic procedure for lightening the colour of teeth. Two mild bleaching preparations are used: either hydrogen peroxide or carbamide peroxide. Differing strengths of gel are used for night and day use. The gel is retained in transparent soft, thin, custom made trays in your mouth, both in clinic and at night.

Why the Evolution System?
The Evolution system by Enlighten is one of the best tooth whitening systems on the market. It does not use lasers or lights. Evidence based research shows that lasers and lights do not offer additional benefit and those who may have had either ‘laser’ or ‘power’ whitening with a light-based system are disappointed with the long term results. This usually is because the effects of whitening were not very good in the beginning or that it faded quickly.

How is the treatment performed?
The treatment involves a very unique bleaching tray that allows maximum contact between the teeth and the bleaching gels. The whitening gels are specifically formulated for a longer duration effect and for minimum sensitivity. The intensive combination of whitening your teeth at home followed by ‘power’ whitening immediate after maximises the bleaching action.

How white will my teeth be at the end of treatment?
This is dependant on the enamel structure of the individual person, and the degree of staining already present. Shade change is monitored at the start, during and at the end of treatment

Will my teeth look too white?
No, natural teeth rarely look too white. Sometimes very white crowns or veneers can look too white because they are made of porcelain.

How soon will I see results?
This depends on the nature and the degree of the initial stains. Everyone is different and just as our hair and skin colour vary so do our teeth. For darker stains, one may need longer a treatment

What are the side effects?
Some users may get sensitive teeth after use. The degree of sensitivity is different from person to person. Any discomfort is usually temporary and should subside soon after use. After a few treatments patients often become more accustomed to the process with a reduction in tooth sensitivity. We advise the use of an anti-sensitive toothpaste during treatment, and/or a fluoride mouthwash

Are the whitening results permanent?
It is usual for the new shade to last for one year, and is dependant on diet and amount of staining. Top-up gel may be needed once during the year.

Is this process safe?
Yes. Research shows that the effect of exposure to whitening gel is similar to one can of soft drink – it’s very safe.

Does the bleaching strip away any enamel?
Absolutely not. With careful use and following the guidelines of an experienced cosmetic dentist the treatment will cause no loss of enamel.

Will the gel whiten my crowns and filings?
No. Many patients may need to change visible crowns or fillings after whitening, to match the new shade.

Can I whiten my teeth while I am pregnant or nursing?
No, we do not recommend this, as current research doesn’t show it to be either safe or harmful.

Can whitening toothpastes replace whitening treatment?
Whitening toothpastes are no substitute for professional tooth whitening. Although these toothpastes can remove stains, they cannot effectively change the natural shade of teeth. In fact some toothpastes are abrasive

Are over-the-counter whitening kits/strips as effective?
Tooth whitening is a complex procedure that should be carried out under the supervision of a dentist after an examination by a dentist to assess your teeth. Some over the counter products may actually harm the teeth, and are not advised. There is no substitute for professionally administered whitening gel with bespoke trays

Should I see a dentist regularly?
We recommend that you see a dentist regularly for examination of the teeth and gums. We also advise that you see a hygienist regularly, for plaque and tartar removal. Hygienist treatment with your dentist is recommended, before you have professional tooth whitening.
