What are Teeth Whitening Strips?
Teeth whitening strips are small polyethylene strips that are coated with a layer of hydrogen peroxide. It is this layer of hydrogen peroxide that acts as the bleaching agent. The teeth whitening kits have separate strips for the teeth of the lower and the upper jaws. These strips have to be pressed firmly against the teeth and left for about 30 minutes. This should be done twice a day at 12 hour hours interval. This is generally done for 7 to 14 days, depending on the strength of the bleaching agent used. These teeth bleaching strips are available in concentrations that range from 6% to 10%. As they are easily affordable and easy to handle, teeth whitening strips are very popular with those who want to be able to do teeth whitening at home.
