Laser dentistry utilizes lasers to address various dental issues. Approved for clinical dental use in 1989, lasers offer a more comfortable alternative to drills for treating tooth tissue. Compared to traditional tools, laser dentistry enhances comfort during hard or soft tissue dental procedures. The acronym LASER stands for 'Light Amplification by Stimulated Emission of Radiation. Over the past two decades, laser applications in dentistry have surged, increasing treatment efficiency, specificity, convenience, cost-effectiveness, and comfort. Laser treatment has proven effective for canker and cold sore pain, root canals, gum disease, inflammation, and reshaping.
