In the 1990s, lasers in dentistry started to become more common. Lasers are utilized in dentistry as a therapeutic instrument or an auxiliary tool. The major objective of employing lasers in dentistry is to eliminate the drawbacks that currently exist with traditional dental treatment methods. The most recent laser technology is used in several dental specialities, including oral surgery, implants, oral medicine, periodontics, paediatrics, and operations. The patient delivery system in dentistry practices has benefited from the usage of lasers since they can perform minimally invasive operations with less discomfort for the patient. The use of lasers in treating oral mucosal lesions is briefly discussed in this article.
