Aim To perform a systematic review to evaluate the post‐surgical effect of low‐level laser therapy after tooth extraction on healing improvement and pain reduction. Material and methods Two reviewers performed a database search of studies published between 1950 and 2015. The inclusion criteria were clinical studies that applied any regimen of low‐level laser therapy after any type of tooth extraction and also compared this regimen with non‐adjuvant therapy. There was no language restriction. All potentially relevant studies were identified by the title and the abstract. After the full‐text analyses of the potentially relevant studies, the selected studies were included in the systematic review. Results A total of 99 non‐duplicated studies were found. After reviewing the articles, only 11 were included. The selected studies were critically analysed and classified in scores. None of the studies fulfilled all of the requirements in the quality assessment. Only four studies presented high methodological soundness. Conclusions A decrease in pain level after tooth extraction was reported after low‐level laser therapy; however, there is no evidence regarding the effect on tissue healing. Adequately powered and randomised controlled trials are required to address this issue.
