Teeth whitening removes build up stains and gives your teeth a whiter appearance. You can choose from a variety of teeth whitening methods, including tooth whitening, at home whitener kits and laser whitening.
There are generally two types of methods for at home whitening of teeth that you can get prescribed by a dentist: Trays and strips. But knowing which one is right for you, and more importantly which one is more effective, used to be a difficult question.
Researches from the Association of Dental Research recently conducted a study to determine the most effective way to whiten teeth. Proctor and Gamble supplied the funds needed for the survey.
These two approaches differ in the amount and type of peroxide they use, and the length of time the materials are pressed against the teeth.
The strips contain about a 14% hydrogen peroxide gel product, while the trays have about 16 to 20 percent carbamide peroxide in its gel substance. The strip is to be worn for a time of 30mins 2 times a day for almost 1 month, while the trays are to be worn overnight, and for only 14days. Side effects are also of concern when testing the two products.
In general, people have fewer difficulties using the strips, and report fewer side effects. Because the trays are worn for a much longer period of time there are more inherent problems associated with them, such as keeping them secure in the mouth, choking hazards, and overexposure to the product. The comfort level and personal choice of the participants played an overall important factor in the test. The whitening strips didn´t cause the discomfort of the overnight trays option. The trays sometimes irritated the subjects gums. Sensitivity might occur if exposed it peroxide every night.
What was discovered:
While the whitening trays have a more concentrated amount of peroxide and are left in the mouth for a greater duration; the whitening strips proved to be a bit more effective than the trays. Strips can cover only the first eight teeth whereas the trays which are capable of a larger cover, can act on your entire teeth. Therefore, persons who deployed the trays for treatment could clean and whiten more teeth.
