When you approach a clinic for laser tooth whitening, the first step will be a pre-treatment checkup for sensitive teeth. The chemicals used in the treatment may make the tooth more sensitive. However, that does not mean that teeth whitening treatment is not advisable for the persons with sensitive teeth. If the person found to be having sensitive teeth, less percentage of hydrogen peroxide will be used in the chemical.
The next step is to remove the stains from the teeth. After that the teeth whitening chemical will be applied all over the tooth and will be exposed to the rays from a laser gun. The light and heat will catalyze the chemical reaction and the teeth will become whiter and brighter.
Laser whitening treatment has not many takers in the beginning and the major reason for this was the high price the clinics used to charge. It was remained as a cosmetic treatment exclusively for the rich and the influential. Later on the popularity increased and as more and more people started opting for it, the charges reduced to a greater extent and now it is affordable even by the common man.
Presently you can see a good number of laser whitening clinics in all major cities. Big cities such as London, New York etc have large number of such clinics and they are updating their technology every now and then to offer the best service to the customers. The clinics engaged in teeth whitening in London have opened many branches in different parts of the city to make it more accessible. Providing a treatment in the neighborhood will certainly make the difference.
