Carbamide peroxide is used by dental professional and at home people all around the world. Another popular teeth whitening chemical is hydrogen peroxide, which is similar to carbamide peroxide but has been around for over a century. Teeth whiteners have been around for over a century but since the early 1990's, teeth whitener kits have become a phenomenon. Carbamide peroxide has become more popular for at home use since the early 1990's. There are many types of forms of carbamide peroxide. Concentration levels for the carbamide peroxide vary from 10% to 36%. The most popular of the concentration levels are the 22%. This teeth whitener provides little to no sensitivity to the teeth while whitening the teeth at a good pace. The teeth whitening process is called oxidation which eliminates the stains from the teeth without harming the enamel in the mouth. The teeth whitening process makes the teeth lighter by eliminating the colored tooth. The teeth whitening process is very simple to do at home. It involves placing the carbamide peroxide inside thermoforming mouth trays. Each thermoform mouth tray is placed inside the mouth for up to 30 minutes daily. The longer it is placed inside the mouth the better the teeth whitening results. Results can form as quick as 5 to 6 hours.
