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.
