The use of oral lasers can be considered a panacea for the treatment of caries, periodontal disease, dentin hypersensitivity, and various oral mucosal diseases, not only cutting the hard tissues of the teeth quickly and efficiently but also trimming the soft tissues of the oral cavity while achieving a good hemostatic and sealing effect. For caries, the laser can remove decayed hard tissues in a minimally invasive manner; for periodontal disease, the laser can inhibit bacteria and sterilization, remove plaque, calculus, and diseased bone; for dentin hypersensitivity, the laser can seal exposed dentin tubules, block nerve conduction and reduce pain; for oral mucosal disease, the laser can promote wound healing, reduce scarring and remove soft tissue pigmentation, etc.
