Types of Laser Dentistry

Dental lasers use focused light energy to perform a variety of procedures with greater precision, less pain, and faster healing compared to traditional methods. Different wavelengths are suited for different tissues. Diode lasers (810-980nm) are used for soft tissue procedures including gum recontouring, frenectomies, and treatment of oral lesions. Erbium lasers (Er:YAG and Er,Cr:YSGG) can cut both soft and hard tissues, making them versatile for cavity preparation, bone surgery, and periodontal treatment without the need for anesthesia in many cases. CO2 lasers provide excellent hemostasis and are used for soft tissue surgeries. Nd:YAG lasers penetrate deeper into tissues and are effective for periodontal pocket decontamination. Laser dentistry offers numerous advantages including reduced bleeding, minimal swelling, decreased need for sutures, and lower infection risk due to the sterilizing effect of the laser energy. Photobiomodulation (low-level laser therapy) promotes tissue healing and reduces post-operative pain. As laser technology continues to advance, its applications in dentistry continue to expand.
