Some of them are very safe as far as the health of teeth concerned while some may cause a lot of health hazards too. Whether it is safe or not, there is one thing common for these techniques that all of them are time consuming ones. In other words, you will have to continue the efforts for weeks together to get a desired result. Conventional teeth whitening treatments offered by dentists too will necessitates visiting the dentist three or more time to get a perfect result. Here the latest technique, laser teeth whitening stands apart. It takes hardly an hour’s time for the treatment and produce immediate result too.
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 Light Teeth Whitening
Another way for better and faster results is the use of a laser light to increase the effectiveness of the whitening gel. When the gel is applied then the laser light can speed up treatment time and give you up to six times whiter teeth.
Results are visible immediately after a one-hour treatment with the laser light and mildly discoloured teeth may not need another in-surgery treatment. However, the dentist will advise you to repeat the treatment at home with a whitening kit once or twice a month to maintain the good results.
What you cannot do at home with a whitening kit is professional procedure for teeth which are root filled, because in this case the bleaching must be internal. The dentist usually drills a small hole to the tooth and fills it with the whitening gel. After that, the dentist will use a temporary filling which has to remain on the tooth until the desired shade is achieved.
Internal bleaching is not possible to be performed at home, and if you have several root-filled teeth you should have in-surgery whitening. When your root-fills are satisfactorily white, you can go on with external bleaching either at home or at the dentist’s surgery.
