Tooth trays in kits

Custom-fitted tooth trays are expensive, since they involve the expertise of a dentist. For those who cannot afford to be attended by a dental professional, there is the possibility of getting self-whitening kits from a brick-and-mortar or online store like Amazon. Each kit contains a small plastic mold that is to be fitted to your teeth. The plastic mold must be heated via boiling to a high temperature so that they can be pliable. Once heated, the tooth trays are to be fitted over one's teeth to provide a snug fit for the trays. Finally, a whitening agent needs to be used along with the trays. One may buy over the counter the peroxide agents that fill the trays. Thinking of using over-the-counter peroxide agents? Better to ask your dentist for a prescription peroxide, since these are usually given at higher concentration or stronger strength for improved whitening action.
