Using light to enhance in-office vital bleaching may increase both efficacy and tooth sensitivity
Deborah Ray DMD
Systematic Review Conclusion
The use of light with higher concentrations of hydrogen peroxide (HP) (25–30 percent) may not be as effective in bleaching teeth as are lower concentrations and increases immediate tooth sensitivity.
Critical Summary Assessment
Limited evidence suggests that light activation in tooth bleaching systems was effective with low concentrations of HP but it increased tooth sensitivity.
