With the myriad of teeth whitening products available, it is difficult to choose one. Let us take a look at teeth whitening trays. They are available either in the dentist office or over-the-counter. They are molded to the teeth, and then they are filled with a hydrogen peroxide containing gel. Finally, they are placed on the teeth where they will hold the peroxide to the teeth for a long period of time.
Over-the-counter teeth whitening trays are mostly limited to Aquafresh White Trays. The gel that comes in this product contains ten percent hydrogen peroxide.
Gels that users get at the dentist often contain more than ten percent hydrogen peroxide, making them more effective. The trays and gel are usually given to a patient after a laser teeth whitening treatment or other teeth whitening treatment in order to complete the finishing touches of the treatment.
The trays have both pros and cons over other teeth whitening products.
They are superior to whitening toothpastes, because whitening toothpastes only contain abrasive materials and do not contain the bleaching agent hydrogen peroxide.
Whitening mouthwashes cannot compare with whitening trays either, because they only hold the hydrogen peroxide to the teeth for a minute or less, while the trays hold the peroxide for a long period, generally twenty minutes.
Whitening strips also have their weaknesses when compared to whitening trays. The strips cannot get in between the teeth into the grooves, since they lay on top of the teeth. However, the whitening trays do.
Unfortunately, whitening trays come with their share of problems, too. Since they are filled with a gel, the placement of the product is more difficult to control. It is easy to have some of the gel get spilled into the mouth in unwanted areas, and it is easy to touch the gel to the gums.
Gel spilling into the mouth will leave an unpleasant taste, but that is the least of your worries. It will cause burning, which will lead to tooth and gum sensitivity. This sensitivity, however, is not permanent, and it will usually subside within twenty four to forty eight hours.
These trays will certainly whiten your teeth well, however. They do not leave spots out like the strips do; there is no “zebra” effect. If you are looking for a teeth whitening product that will be the most thorough, and you do not want to spend the money on a laser teeth whitening procedure, then white trays would be a good choice if it were not for their problem of easily burning mouth tissue. As it stands, they are not recommended for this reason.
