Explanatory note

Not available for this PSP


Comparison to no treatment/placebo. In terms of health outcomes, low quality evidence 
Regarding adverse events, most commonly reported were tooth sensitivity and oral irritation (more prevalent with higher concentrations of the active ingredient). Some evidence that activation of bleaching agents by heat, light or laser may have an adverse effect on pulpal tissue. All studies are short-term and predominantly sponsored or conducted by the manufacturers. Long term evidence on oral health related quality of life and adverse events is missing. 

For full details of the evidence checked, please see the spreadsheet of data held on the JLA website.
