Frequently Asked Questions about Tooth Whitening:
How long will the results of tooth whitening last?
The effects of whitening are not permanent and will fade over time as stains build up on your teeth. This happens at different rates for different people depending on your diet and habits. If you are a smoker, drink a lot of coffee or red wine then the effects will wear off quicker. Results can last anywhere from a few months to several years.

Should I have my teeth cleaned before I whiten them?
Some discolouration of your teeth may be caused by surface stains which can be cleaned away by a hygienist. It is advisable to have a thorough cleaning with a hygienist prior to starting the tooth whitening process to ensure that there is no plaque or tartar build up which can prevent the whitening solution from reaching certain areas of your teeth.

Can I whiten my teeth if I have crowns, veneers or bridges?
If you planning to have a crown, veneer or dental bridge fitted and would also like to whiten your teeth, it is best to carry out the teeth whitening before your dental work. This is because teeth whitening treatments will only change the colour of natural tooth material. If you already have a dental restoration like a crown or veneer and you whiten your teeth, you may need to change the restoration afterwards to ensure the colour matches.

Does tooth whitening make teeth sensitive?
On the days that you are whitening your teeth, you may find they are more sensitive to hot and cold than usual. To help with this you can try using toothpaste that is specially designed for sensitive teeth during the whitening process. The sensitivity should not persist once you have completed the treatment, if it does you should consult your dentist. You should always have a full dental health assessment with your dentist before starting tooth whitening to ensure that there are no underlying problems which could be affected by the whitening treatment.

Can I whiten my teeth if I suffer from sensitivity?
If you suffer with sensitive teeth then you should consult your dentist before having tooth whitening treatment. It may be that there is a cause of the sensitivity that can be addressed before you start whitening.

I’ve seen tooth whitening offered by my local beautician, why do I need to see a dentist for whitening?
It is illegal for anyone other than a dentist or a suitably trained Dental Care Professional (DCP) under the supervision of a dentist, to carry out teeth whitening. If you choose to have whitening with anyone other than a qualified dentist or DCP working to a dentist’s prescriptionthen you are putting your health and wellbeing at risk. One of the risks you face is burns to your lips or gums from incorrect use of the whitening solution or badly fitting whitening trays. Your dentist will be able to give you a full assessment to make sure that it is safe to whiten your teeth and provide you with all the correct instructions to carry out the treatment safely and effectively.

I have white spots on my teeth, will these disappear if I whiten my teeth?
The whole tooth will lighten when you whiten your teeth so the white spots will remain visible. There are other treatments available to remove white spots such as ICON which is available at Harley Street Dental Studio.
