It is natural for teeth to become darker over time, and some people have naturally darker teeth. Teeth staining can also be accelerated by things like smoking, coffee drinking and red wine drinking. It may get to the stage where you think something needs to be done about it and this is when it is time to visit your local cosmetic dentist for deep bleaching teeth whitening treatment.
The deep bleaching tooth whitening method works using peroxide gels. These work by getting oxygen inside the structure of the tooth. The oxygen breaks up larger molecules on the tooth and turns them into smaller molecules. Large molecules appear as darker on the teeth, whereas smaller molecules appear lighter meaning that the smaller the molecules are on the teeth, the whiter the teeth will appear.
You will probably be asking yourself how the bleaching gel is applied to the teeth. What the dentist does first of all is to take an impression of the teeth in order to make a whitening tray or gum shield which fits snugly onto the teeth. This tray will be filled with the gel and worn every night for about 14 days in a row. The patient will then return to the dentist for a final intensive bleaching which will last about 1 hour.
The patient should notice a massive difference in the whiteness of their teeth after the initial treatment. The patient should also make sure that they wear the tray once every couple of months. If they do this and the tray has been made properly the teeth whitening effect should be permanent.
One question that patients will often ask is whether the treatment causes any sensitivity. There is sometimes some temporary discomfort at the beginning but as teeth whitening Bolton dentist Cahill Dental Care state: “You may get some transient sensitivity, however your dentist will recommend desensitizing tooth paste for you to use also.
