A laser can do many things in a dental setting.
It can remove tissue in a fine and controlled way. This will often replace a scalpel in many procedures, and it seals as it cuts for fast healing and less bleeding. Lasers provide several benefits in a dental setting. They promote faster healing for patients, and they can help reduce sensitivity in teeth by causing the pulp fingers to pull back from the dentin.
People often wonder if lasers are painful when used during dental procedures. Lasers can trick the nervous system into feeling less or no pain, although many times we will use anesthetic when using a laser for the comfort of the patient.
