A laser device uses light energy to improve periodontal health. It does not require anesthesia, making it a less invasive option. Laser treatment can target and remove diseased gum tissue, stimulate the growth of healthy tissue, and eliminate bacteria. The laser's precision allows for more accurate and controlled treatment, reducing the risk of damage to surrounding tissues. Overall, laser therapy is an effective and efficient method for improving periodontal health without the need for anesthesia.
