• To combat the coronavirus pandemic different vaccines have been developed. However, diverse adverse effects have been reported due to their use, including oral manifestations. Our objective is to review the existing bibliography to analyze what complications these vaccines have caused in the oral cavity.

  A bibliographic search was conducted by two independent reviewers (TS and CL), in parallel in 6 electronic databases (PubMed, Scopus, Cochrane, Google Scholar, LILACS, BioMed Central). A total of 22 articles were analyzed.

  The most frequent adverse effect was oral lichen planus, with a higher prevalence in women and after the Pfizer mRNA BNT162b2 vaccine.

  These complications are minor and resolve with treatment, so the benefit of the use of vaccines outweigh the potential risks associated with these.
