The home teeth whitening tray based system containing Carbamide Peroxide became immensely popular as the teeth whitener in the dental offices after a clinical survey related to it was published in the 1989. The study stated how a dentist could easily craft a plastic bleaching tray which was fabricated in a way that it fitted comfortably in the person's mouth on the teeth. It also mentioned how a dentist could dispense a peroxide based teeth whitener to the patient. The patient would then take home teeth whitening product and place the whitener on to the bleaching tray.

The patient would wear the tray for a certain time period during the day. This process would continue for weeks and the whitening effects would take place slowly. The practicality and the easiness of this home teeth whitening tray became so popular that now you can find over the counter products related to it. The technique is performed at the dentist's office very easily. As a matter of fact you must initiate this process at the dental clinic and then carry it back home.

Primarily the dentist performs an examination of the teeth. After this he takes impressions of the teeth from which he can create the plaster molds. Then customized bleaching trays are made on the patient's dental molds from thin and soft plastic. The dentist then puts some Carbamide Peroxide gel on the home teeth whitening tray and also instructs the patient on how to place the whitener on the tray. He will also tell you how long you must wear it during each bleaching treatment.

The take home teeth whitening tray is an effective way to whiten the teeth. The patient should return to the dentist from time to time. This will help the dentist in checking the progress made by the patient. Also the dentist will examine if any side effects are taking place. In case the staining is very severe and is not getting removed after the initial treatment, the dentist might add some more gel to the home teeth whitening tray.

There is a lot of difference between the take home teeth whitening trays provided by the dentist and the ones that are found over the counter. This is because the over the counter products do not involve any dental examination. It is essential to get your teeth examined professionally your dentist will always ensure that you are in a good and healthy condition at all times during the treatment. But the OTC take home teeth whitening products do not have that guarantee. You may fall victim to wrong products. Visual inspection of your teeth is very essential before the dentist gives you the home teeth whitening tray. At times photographs of the teeth are taken. After an overall examination the dentist will determine if you are capable of getting the home treatment done.

Moreover these OTC home teeth whitening tray are not custom made, you have to use the ones which are already on the shelf. It is not necessary that they fit you.
