The incorporation of laser technology in dentistry has transformed conventional therapeutic approaches, offering distinct clinical advantages over traditional methods. Operating via photothermal, photochemical, and photomechanical interactions, lasers enable precise tissue modification with minimal collateral damage. Their ability to ablate, penetrate, and disinfect has shown promising outcomes in various endodontic procedures, including root canal therapy, vital pulp therapy, management of dentinal hypersensitivity, and control of pulpal and periapical pain. Depending on their wavelength and clinical indication, lasers such as diode, Nd: YAG, Er: YAG, and CO₂ are selectively employed. In periodontics, laser-assisted therapy enhances treatment outcomes through excellent decontamination, reduced bleeding, accelerated healing, and improved patient comfort. This narrative review delves into the underlying mechanisms, current clinical applications, and emerging advancements in laser technology in endodontics and periodontics, highlighting their challenges.
