Abstract: Low Level Light (Laser) Therapy (LLLT) is the direct application of light to stimulate cell and tissue responses (photobiomodulation) to promote healing, reduce inflammation and induce analgesia. Studies have demonstrated its application and efficacy for the treatment of a range of injuries and diseases at many sites within the body. However, its application in dentistry and for oral disease treatment has been limited. This review aims to provide background information on LLLT which relates to its current application in medicine, its mechanism of action and delivery parameters, while considering its potential for dental and oral therapeutic applications.

Clinical relevance: Low level light therapy has the potential to have substantial impact for the treatment and management of oral diseases and pain.
