During the process of teeth whitening, the teeth bleaching procedure is used. The mouthpiece tray is used as a container in, which the whitening gel is poured in. It prevents the gel from being washed away by the saliva.
There are proper methods to put the bleaching gel inside the mouthpiece tray. Initially a thin layer of whitening gel has to be applied inside the tray. The teeth come into contact with this part of the tray. Once the tray is fitted well inside the mouth, the rest of the whitening gel can be poured into it. The gel needs to be evenly distributed. You have to try several times with the gel in order to find out, which gel is suitable for your tray. But if the gel touches the gum, it might cause gum irritations and gum ulcers.
Customized and standard are the two types of mouthpiece trays available in the market. You will feel more comfortable and safe with the customized tray as it will fit perfectly into your mouth. It shares a high resemblance with a teeth guard. A very soft material is used to make these customized trays, which provide a protection to the entire set of teeth during the teeth whitening procedure. In fact, it stops the gel from spreading over the gum. The presence of hydrogen peroxide in the gel leads to several side effects, if they come in direct contact with the gum.
However, you will not find the standard trays as comfortable as the customized trays. While buying the teeth whitening kits over-the-counter, you will see that the standard trays are tagged along a whitening gel. The application of gel goes through similar procedure but the gel applied in the standard mouthpiece tray needs to be kept for at least 30 minutes. The only demerit of this tray is that it does not fit properly into the mouth. Often it fails to cover the entire teeth during the bleaching procedure and if the gel comes in contact with the gum, it might cause some side effects.
It can be concluded that the customized trays are far more beneficial that the standard trays. The licensed dentists make these customized trays and are generally used by them in the procedure of laser teeth whitening. A laser whitening treatment is conducted only by a licensed dentist and thus it is far more effective than any other methods of treatments.
Over-the-counter products are seldom recommended by the dentists. If you are opting for any dental product, make sure that those products are approved by the American Dental Association.
