Sadly, many of life’s treats – coffee, tea, red wine, fizzy drinks – can take their toll on your teeth. Common garden ageing can also make your teeth lose their virgin white sheen.

There are four ways that we can help you to achieve a whiter, perfect smile.

Immaculately clean teeth. Hayley, our hygienist, uses a technique called air abrasion which removes heavy surface staining from discoloured teeth and leaves your teeth naturally clean. Please click here for more info on air abrasion.

In-office dental whitening
We use Zoom III Power dental whitening which we carry out in the practice. It whitens stained teeth by an average of 8 shades and it takes under an hour. It’s fast and affordable and it works. It’s the McLaren F1 of tooth whitening.

Home dental whitening system
It works on a day-to-day basis and usually takes 2–3 weeks. It has very good results and can be done at your convenience.

Porcelain laminate veneers or crowns are another way of attaining the perfect whiter smile. They are suitable for teeth that are very discoloured or have been previously restored. Please visit our dental veneers ordental crowns section for more information.

We can help you to decide which is the best route for you.

Frequently asked questions

What causes tooth discolouration?

The most common causes are tea, coffee, tobacco, red wine, coloured drinks and ageing. We’re not suggesting a complete veto on all these things. Calculus or tartar can also affect the colour of teeth.

It is also possible to have stains that are inside the tooth. These are called intrinsic stains. They can be caused by exposure to too much fluoride as a child while teeth were developing.

Other causes include antibiotics. They can stain a child’s teeth if taken under the age of 8 or if taken by the child’s mother during the second half of pregnancy.

Tooth whitening is most effective on surface stains caused by age, foods or drinks.

What is dental whitening?

Whitening is the process through which your teeth are made cleaner and brighter. There are 2 main types: Zoom III power whitening and at-home tray-based whitening.

What is at-home tray-based dental whitening?

We take an impression of your teeth to make one or two custom-made mouthpieces to fit you. The number will depend on whether you are having both upper and lower teeth whitened.This is filled with whitening gel and is worn for between 16-32 sessions. They can be worn at home.

It is important that the mouthpieces fit well. A close fit helps the whitening agent to remain in contact with your teeth. Over-the-counter mouthpieces are unlikely to fit perfectly and they can cause gum irritation if the whitening agent seeps out.

The results are typically 6 shades whiter.

What is Zoom III Power dental whitening?

The very latest and most effective whitening method is an American import called Zoom Advanced Power system. We call it by the acronym ZAP — it’s less of a mouthful.This is carried out in the practice and has the dual advantage of being much quicker and more effective.

We apply a light-sensitive whitening gel to your teeth. This gel allows oxygen to enter the enamel and dentine bleaching any coloured substances. It leaves the structure of the tooth relatively unchanged.

We then activate the gel using the ZAP light. This light helps the gel penetrate the tooth.

A recent study has shown that the ZAP lamp increases the effectiveness of the gel by 26%.

The results are typically 8 shades whiter.

What method do you advocate?

We are confident that both methods will deliver significant whitening. We might recommend one over the other once we have understood your lifestyle and examined your teeth. It is important to realise that all teeth are different and that teeth whiten at different rates and by different amounts. We will advise you which method suits you best.
How much whiter can I expect my teeth to be?

The Zoom III power whitening system improves your tooth whiteness by an as much as 8 shades, as measured by the Vita Classic Shade Guide. Fillings or crowns won’t change colour and may need to be replaced, depending on where they are in your mouth.

The at home trays typically whiten teeth by 6 shades.

Will whitening change my life?

Well, it will certainly help you to love your smile… and it’s not a bad place to start.

How long does it take?

Zoom III Power Whitening: It takes very little time. The procedure begins with a preparation period followed by as little as 45 minutes whitening.We do recommend a pre-treatment cleaning session to maximise the whitening potential. At-home trays: You will need to wear the trays for between 16-32 sessions.

With Zoom III Power Whitening, how long will the whitening last?

The results can last up to 10 years and your teeth will certainly be lighter than they were.

You will need to follow simple post-whitening care instructions – flossing and brushing twice a day. Your mouth’s health is integral to the success of the whitening. Regular visits to a hygienist will ensure that your teeth are as fighting fit as they can be.

Are there any risks?

Whitening is unlikely to cause serious side effects, although some people’s teeth may become more sensitive for a short while. You may get mild gum irritation as well. This is more common if you have any gum recession around the neck of the teeth.

Sensitivity can occur in some patients during the Zoom III Power Whitening treatment. The light generates minimal heat, which is the usual source of discomfort. On rare occasions, minor tingling sensations are experienced immediately after the whitening but should not last long.

Is Zoom III Power Whitening suitable for everyone?

Tooth whitening is a well-established procedure in cosmetic dentistry. Hydrogen peroxide solution, the active ingredient in whitening, has been used safely for many years in the treatment many dental procedures. However if you are light sensitive, undergoing PUVA therapy (Psoralen +UV Radiation), photo-chemotherapy or if you have a melanoma, we’d recommend tray-based whitening instead.

Do whitening toothpastes work?

There are several whitening toothpastes on the market. They do not affect the natural colour of your teeth but they may be effective at removing staining and therefore may improve the overall appearance of your teeth. Whitening toothpaste may also help the effect last, once your teeth have been professionally whitened.

Look for the British Dental Association’s accreditation symbol on the packaging of oral care products. This guarantees that an independent panel of experts has scientifically and clinically checked the claims made about the product.

What about payment options?

We offer 0% finance loans, subject to the usual terms and conditions and status requirements. We also offer corporate and personal dental schemes and we are happy to accept personal insurance. E.g. Denplan or BUPA. Please click here for more information.
