Teeth Whitening


Teeth Whitening

Teeth whitening is a quick and easy way to boost your confidence and combat common causes of tooth discolouration.

What is teeth whitening

Teeth whitening – or bleaching – is a cosmetic treatment where a gel is applied to your teeth to make them appear lighter.

A bleaching gel is placed in to a custom-made soft tray which is worn over your upper and lower teeth, either overnight or for at least 2 hours during the day. This process is repeated daily for around 16 days, gradually brightening the appearance of your teeth.

A little bit of sensitivity at the start is perfectly normal and disappears within a few days of the treatment ending.

At Kelvin House we provide you with the Opalescence Home Tooth Whitening Kit complete with upper and lower soft trays custom moulded to your teeth.

How does teeth whitening work?

Most of the teeth whitening treatment is carried out by you, at home. First your dentist takes an impression of your teeth at the surgery, in order for your custom trays to be fabricated. You will then need to go back when they are ready to make sure they fit and for your dentist to show you how to use the whitening gel. After that, it’s simply a case of sticking to the daily treatments. Of course, if you have any issues or experience discomfort, you should let your dentist know straight away.

The gel contains an active ingredient – 10% carbamide peroxide – which breaks down and releases oxygen into the tooth enamel, causing it to gradually lighten in colour.

We strongly advise against patients buying DIY home teeth whitening kits. Your Kelvin House custom trays have been custom made so that they mould precisely to your teeth and gums, stopping the gel from coming into contact with them (and from saliva getting underneath). If this does happen, it can cause unpleasant symptoms like blistering and sensitivity and possibly uneven results.

Done properly, with the help of a professional, teeth whitening is a fast, effective and affordable way to transform your smile.

Need to knows

Don’t expect ‘brilliant white’ results. Your teeth should brighten by several shades, which will make a significant difference

Teeth whitening isn’t permanent. It can last for between a few months and two years.

It will last longer if you drink less coffee, tea and red wine, and don’t smoke

A good daily oral care routine will help keep your teeth white and bright

It is normal for existing white flecks on your teeth to appear a little brighter immediately after treatment but they fade back in a matter of weeks

Teeth are naturally a little darker along the gum line and may remain that way even after whitening treatment
