Teeth Whitening

Over time, our teeth can discolour and become more yellow as a result of the thinning of the dental enamel. This is because enamel reacts to acids coming from food and drinks. Teeth whitening is a simple and extremely effective way of restoring the colour of your teeth, give them and you a whiter, more vibrant and youthful appearance.

What is teeth whitening?

Teeth whitening is a procedure that is a form of general dentistry. As such, it should only be carried out by a qualified, regulated dentist or dental professional. We have highly experienced hygienists who are trained to carry out professional teeth whitening in our Exeter dental practice. Teeth whitening treatments use chemicals that can potentially cause damage to your gums if the correct dosage is not applied in the right way.

Professional teeth whitening works better than a home kit

The professional process involves taking moulds of your teeth and providing you with bespoke customised gum shields. You then take those gum shields home and use them to apply the tooth whitening agent. Remember we will carefully select the correct strength and type of tooth whitening agent that matches your needs.

We recommend that whitening your teeth is best done at night, after two to three weeks, the teeth will have lightened significantly.

The procedure involves no damage to the teeth and isn’t painful. Some people may experience a short term feeling of transient sensitivity.

Is tooth whitening done by a dentist more effective than ‘over-the-counter’ kits?

Yes, definitely. Home tooth whitening kits that are sold in many supermarkets are not illegal but they have very limited whitening effect. They do not contain enough whitening agent to be entirely effective or very long-lasting.

Everyone’s teeth and mouth are unique. Mouth guards provided in ‘do-it-yourself’ tooth whitening kits are mass-produced, not custom-made. They will never fit as well as mouth guards or gum shields that are tailor-made by a professional.

How long does teeth whitening last?

You should have whiter teeth for up to three years. This largely depends on your lifestyle – whether you’re a smoker or a non-smoker or if you regularly consume liquids or foods that are known to stain teeth like curry, red wine, tea and coffee.

We recommend that you ‘top up’ your treatment at home every six to twelve months to keep your smile as bright and white as possible.
