Things to know- Teeth Whitening


The quest for the perfect pearly whites is one that has been around for decades and the technology that has been developed to fulfill this has come along way. Here at Space Healthcare we offer a Tray-Based home teeth whitening treatment. This consists of an initial dental consultation to establish whether your teeth are suitable for this type of treatment, if your teeth are suitable for treatment we will then make impressions of your teeth which will be used to produce custom-made whitening trays to perfectly fit your top and bottom teeth.

The whitening trays are made from a soft vinyl rubber tailored to fit the exact contours of your teeth and moulded to fit into your mouth, this enables the whitening gel to make close contact with your tooth enamel to produce a consistent whiter smile. Some patients may experience sensitivity during the treatment. On rare occasions, patients may experience tingling sensations in the teeth immediately after the procedure,  however these effects subside shortly after use. It is not advised to use whitening systems if you have decay or defective fillings, or if you have active gum disease, which is why we always carry out a thorough examination of your mouth before we start any form of whitening treatment.

Some ready-made trays that are provided with other home teeth whitening products often do not allow the close contact that is required to create such even results, and some home kits may not contain enough of the whitening product to be effective, these are only minor problems compared to some of the other problems that can occur from these products. If the whitening tray does not fit correctly then some of the bleaching gel may leak onto your gums and can even be swallowed which can cause ulcers, blistering, sensitivity and damage to your tooth enamel.

Research conducted by the British Academy of Cosmetic Dentistry also found that cheaper home whitening kits may contain high levels of bleach. EU recommendations state that the level of Hydrogen Peroxide (an active ingredient in whitening gel) should not exceed 6%, however some websites are selling kits that contain nearly double the recommended level, some even containing acid that can erode patients teeth, causing them to stain even more.

No matter what treatment you use there is a chance that your gums and teeth can become more sensitive because of the chemicals being used in the procedure, especially if you already have sensitive teeth, however with a professional consultation the chances of this happening are significantly reduced.

Whilst teeth whitening may not be a permanent treatment it can last up to several years, which can be extended by a regular maintenance program with occasional top up sessions and the avoidance of foods and drinks known to cause staining to your teeth, such as red wine, tea or coffee.

Dentists are currently being faced with a new phenomenon called ‘Bleachorexia’ which refers to those that have an obsession with bleaching their teeth in order to get a whiter smile. If you over bleach your teeth they can become brittle and chalky because of the bleaching agent, Carbamide Peroxide, which can lead to hypersensitivity, gum irritations and even translucent blotches appearing on the teeth. Many patients ignore the guidelines set out by their dentist and bleach their teeth more frequently than is recommended which is why these problems often arise, in moderation and with the correct guidelines followed teeth whitening can be safe and effective. Chlorine Dioxide, another ingredient found in many of these treatments has also been know to leave patients teeth brown or discoloured after the initial process.

There are also still many people who choose to go to extremes to achieve a dazzling smile, including rinsing with Domestos and Toilet Duck, which can result in chemical burns or the stripping away of your tooth enamel. Once the tooth enamel has been stripped away it will not regenerate which exposes the dentine below leaving teeth with a brown colour permanently.

Achieving the white as snow perfect smile many celebrities have is actually near impossible as they are often the result of porcelain veneers and not teeth whitening treatments or products, however if you’d like to see what results our safe teeth whitening treatment can offer then pop in for a consultation.
