Tooth Whitening for a Better Smile
A beautiful smile can make impossible thing possible. Have you forgotten the heavenly smile of your daughter when she was just a baby? Unfortunately teeth are whiter in children and the whiteness reduces gradually as we grow older. This depends upon many factors. As we grow older, the enamel of the teeth becomes less porous, leading to easy deposition of dirt. Our eating habit, cigarette smoking, chewing tobacco, some antibiotics like tetracycline, habit of sipping excessive tea or coffee can endanger the white glow of our teeth of childhood. Therefore you need something to restore the whiteness. The teeth whitening procedure is at your service.
Teeth whitening or tooth bleaching is a cosmetic dentistry procedure. The dental surgeon removes the dirt and debris that pile up over your teeth for years with some modern techniques. Practically speaking, any product that can remove the dirt from the teeth can be a teeth whitening substance. This way, toothpaste is also considered as teeth whitener. And undoubtedly, if you brush your teeth regularly and in a scientific way, tooth paste can make your teeth glow for long. Tooth bleaching is a term that signifies artificially whitening teeth to such extent that the white color is much more than normally possible shade.
The chemical can be applied either in a dentist’s chamber or there are take home kits. At the clinic, the doctor will first apply a protective gel over the gums to guard it from the harsh tooth bleaching agents. Then the bleaching gel is applied and the protective tray is put into proper place. After 15-20 minutes, when the bleaching process is over, the tray is removed. Generally the process has to be repeated depending upon the degree of staining. Using laser beams, the dentist tries to penetrate through to the inner dentin layer. In the cases of deep staining, this process only works. The whole procedure should not take more than an hour and you can go home just after the dentist finishes his job.
Tooth whitening is not a permanent procedure. It has to be repeated for some touch ups. The gap for each sitting depends upon the lifestyle of the person.
As every good things has its price, tooth whitening has some potential risks also. Chemical burn injury to the gums caused by bleaching agents is most common. Persons having weak gum (patients of pellagra and difficulty in blood coagulation process) should think twice before adopting a tooth whitening procedure. It is also not suggested below the age of 17 years (when most of the permanent teeth have erupted), pregnant and lactating women.
Tooth Whitening for a Better Smile
There are two methods available for teeth whitening – using a controlled laser beam to make the stain material in small particles and a teeth whitening gel that has to be applied over the teeth after wearing a protective tray. The gel contains bleaching materials in the form of hydrogen peroxide or ecarbamid peroxide. Their duty is to penetrate through the teeth enamel and oxidize the tough stain particles only to be expelled from inside. This debris accumulates over the protective tray.The chemical can be applied either in a dentist’s chamber or there are take home kits.
