Results from getting teeth whitened

What is Teeth Whitening?

Teeth whitening is a simple cosmetic process that can give dramatic results in the appearance of your teeth. Tooth whitening will lighten the colour of your teeth without having more complicated work done such as veneers or crowns. The degree of whiteness achieved will vary from person to person and with the type of bleaching process chosen.

Teeth are naturally a yellow or greyish colour which becomes darker as we get older. Food and drink such as red wine and coffee can also cause our teeth to become darker. There are also other reasons why teeth can darken, such as decay, smoking, and the taking of certain antibiotics. Dark teeth are very ageing and just do not look clean.

It is essential to have your teeth whitened by a dentist so that the cause of darkening can be diagnosed and the appropriate method of whitening used for your situation. Every case is different, however it is usually straightforward.

Over the counter products are not very effective as the permitted level of the active ingredient is only 0.1% hydrogen peroxide. That is 0.001666 (roughly 1/100) as strong as the products that a dentist can use. This is why they are not very effective. To make up for the low concentration they sometimes contain abrasives that scour your enamel which can be damaging.

Tooth whitening in the UK is considered by the General Dental Council to be the practice of dentistry. Any non-dentists whitening teeth in gyms, shopping centres or hairdressers are doing so illegally. Dentistry can also only be practised from a location that is regulated and inspected by the Care Quality Commission. Gyms, shopping centres and hair dressers do not fall into this category.

If you would like to have your teeth whitened with products that are actually clinically proven to lighten the shade of your teeth, and by practitioners who are properly trained to use them, please book online here or call us on 020 8748 1381.

Who should have Teeth Whitening?

More and more people are choosing to whiten their teeth to make their smile more attractive. First impressions are important when meeting people and a whiter, healthier looking smile is always an advantage.

We would recommend that anyone who wants whiter teeth should have tooth whitening, as the procedure is very straight forward and virtually risk free. However, if your teeth are consistently darker in colour than you would like, it would be worth booking a dental check-up to find out what the cause of this discolouration may be.

What happens when I have Teeth Whitening?

There are broadly three ways a dentist can perform tooth whitening.

The Gold Standard – Custom Teeth Whitening Trays

The dentist makes custom made whitening trays and then supplies you with the trays and gel (usually 10 to 18% carbamide peroxide). You then apply the gel to the trays and wear the trays at home. This should be worn for two to six hours and a typical course is 12 treatments. The longer it is worn the better it works so sleeping with the trays in position is ideal. The treatments do not have to be on consecutive days, so skipping days is not a problem as the effect is cumulative. This way of whitening is considered to be the gold standard in teeth whitening as it has been clinically proven to be the safest method. 10% carbamide peroxide is the best as the stronger gels cause more transient sensitivity.

This procedure costs £325.

The Silver Standard – Generic Teeth Whitening Trays

The dentist can supply you with a kit that allows you to put a tray over your teeth with gel (6% hydrogen peroxide) inside the tray. The trays are not custom made so you mould the trays to form around your teeth yourself. This can be worn for two to three hours and then discarded. Several applications will be needed. This is the cheapest form of dentist teeth whitening but is not as effective as the first method.

This procedure costs £150.

Laser/Light Activated Teeth Whitening

The dentist can do the whitening for you in the practice. 6% hydrogen peroxide is used and the gels are “activated” with a light or laser which also gives off a bit of heat. Some dentists, however, can mislead their patients in how effective this treatment is. This is because if someone were to sit with their mouth open for 45 minutes without any treatment being done to their teeth, the teeth would whiten through dehydration. It can take up to 4 days for the teeth to rehydrate and return back to their original shade. So if the dentist does one application of light/laser activated whitening then the immediate effect will be very good, partly due to dehydration.

At 92 Dental we offer 1 session of light activated whitening and a silver standard take home kit that allows you top up the procedure. This ensures that results are long-term, and caused by the whitening that you pay for, rather than simply by dehydration.

The cost for light activated whitening, when in conjunction with silver standard home whitening is £500.
