Frequently Asked Questions

What is teeth whitening?
Teeth whitening is a bleaching process that lightens the discoloured enamel and dentine in your teeth.

What causes these discolourations?
There are many causes of discoloured teeth. The most common are drinking tea, coffee, cola drinks and red wine and smoking. Other causes are the natural yellowing of teeth due to ageing and the use of antibiotics or excessive fluoride consumption during tooth formation.

Is teeth whitening safe?
Yes, considerable clinical and laboratory research has shown that the teeth whitening gels have no adverse effects on the teeth.

How long will the results last?
Your teeth will always be lighter than they were before and you may never need to repeat the procedure again. However, depending on the amount of tea, coffee etc you drink and if you smoke you may need to touch-up your teeth every 6-12 months.

What side-effects can I expect?
The teeth may be sensitive to hot/cold while using the whitening products. This will cease upon completion of the treatment. The whitening gel may cause irritation or a burning sensation in the gums. This is why the custom-made trays are generally trimmed to cover only the teeth. If the gums appear white following gel application it is a sign that too much gel is being used causing the gel to come into contact with the gums so always follow the instructions provided with the whitening kits. This white appearance is a temporary and harmless side effect.

Will the whitening gel damage my restorations?
No your fillings and crowns will not be damaged however sometimes amalgam restorations may leave a grey residue in the trays as the gel removes the surface stains off the fillings.

What is the difference between laser whitening and the at-home whitening products on Teeth Whitening Online?
Laser whitening is performed by the dentist who applies a 35% hydrogen peroxide preparation to the surface of your front teeth and shines a light to cause a chemical reaction in the peroxide. This procedure will give the same result as take-home products but only takes 1 hour. The downside is that the cost of such treatments are very high and may be at least 4-5 times the cost of treatments provided by Teeth Whitening Online which will provide a similar result.

Can I use whitening gels while pregnant?
We do not recommend that you use any tooth whitening product whilst pregnant or lactating.
