New whitener bleaches teeth with less sensitivity
• Dental Health • Jun 16 05
A new type of tooth whitener contains extra ingredients that reduce the sensitivity that often follows bleaching, according to new study findings.
Dr. Frederick Eichmiller, based at the American Dental Association’s Paffenbarger Research Center in Gaithersburg, Maryland, explained that people often complain of tooth sensitivity to cold and brushing over the few days following bleaching.
Sensitivity occurs because bleach cleans teeth extremely well, he said, and in the process, helps open pores found in the surface of teeth.
