Capsaicin is a bioactive compound found prominently in L. plants and takes on a pivotal role in their characteristic spiciness. Previous studies have delved into the potential analgesic effect of capsaicin in various oral conditions, such as oral neuropathic pain, trigeminal neuralgia, oral mucositis, temporomandibular joint disorders and burning mouth syndrome. Capsaicin has also demonstrated promise in inhibiting the proliferation of different oral cancer cell lines. Its antimicrobial properties have also been shown to inhibit the growth of oral pathogens associated with dental caries, periodontitis and oral candidiasis. However, to harness its benefits effectively, more studies are required to establish optimal dosages for pain relief while minimizing adverse effects. In addition, investigation of the effect of capsaicin on nonpathogenic oral bacteria and viruses is warranted. Human-based research is crucial for elucidating the biomolecular mechanisms underlying the properties of capsaicin, potentially leading to the development of more effective interventions for oral health problems.
