Opalescence Tréswhite Supreme at-home tooth bleaching system is now available from Ultradent. The kit uses the Opalescence PF formula, which whitens teeth with less sensitivity while rebuilding enamel and preventing caries, according to Ultradent. A 2004 study in the Journal of the American Dental Association of 7 carbamide bleaching agents and their effects on enamel microhardness found that higher concentrations of carbamide peroxide with 0.11% ion fluoride can bleach teeth in a shorter period with fewer hazardous effects on the enamel mineral content1. |
A 2005 study in Operative Dentistry looked at the effect of bleaching agents on caries susceptibility2. This study found that specimens treated with 20% carbamide peroxide with PF (0.11% fluoride and potassium nitrate) were less susceptible to caries than their controls.
