It's a bleaching process that removes the stains in enamel and dentine of the teeth.

The most common causes are ageing, consumption of staining substances like coffee, tea, cola, tobacco and red wine, trauma, nerve degeneration and old restorations. During teeth formation, consumption of tetracycline or excessive fluoride may also result in discolouration.

Teeth whitening is suitable for people with healthy teeth and gums who do have veneers or crowns on front teeth.

smilestudio provides 2 main types of treatments: wy10 'Laser' Chairside (one hour) whitening and wy10 Trays Whitening (home whitening). Please refer to the treatments section for more information.

wy10 Laser is a one-hour chair-side treatment that leaves teeth up to 10 shades whiter with zero sensitivity. With home whitening, you follow a simple procedure at home, attaining optimum results after about two weeks. Teeth are left up to 8 shades whiter after treatment. It is the more cost-effective option.

We use the wy10 system with a patented activator to give faster and better results. From our experience, it works better than the Zoom!® system we used before,  The Zoom system is known to cause sensitivity whereas the wy10 system with its zero-sensitivity technology is comfortable for the customer. Scientific studies also showed that the wy10 gel is more effective than the Zoom!® gel.

No, the treatments do not change the intrinsic colour of these man-made materials. However, surface stains will be removed.

Both treatments use an oxygen releasing whitening gel, which is placed against the surface of your teeth. As oxygen enters the enamel and dentine, it whitens the coloured substances. Only the teeth colour is made lighter; the structure of the teeth is unchanged.

Results last for up to two years, when further treatment will be needed.

Yes! Research and clinical studies indicate that whitening teeth with hydrogen peroxide under professional supervision is safe for teeth and gums.

Occasionally, some people experience temporary teeth sensitivity during or after the treatment. These symptoms always disappear within 1-2 days after interruption or completion of the treatment. At smilestudio, we pioneer a zero-sensitivity technique that all but eliminates this side effect.

No. Current law prohibits OTC products to contain enough active ingredients for effective teeth whitening. The qualities of Internet purchases are not regulated. They are mostly ineffective and can be harmful to your teeth. For peace of mind, get professional advice and have your teeth whitened only by dentists and dental team registered with the General Dental Council.
