Anesthesia-free Painless Laser Tooth Preparations is a laser-assisted procedure for anesthesia-free tooth preparation before filling placement is a minimally invasive procedure that uses a laser to prepare the tooth for a filling. The laser is used to remove only the decayed portion of the tooth, leaving the healthy tooth structure intact. This procedure is much more comfortable for the patient, as there is no need for anesthetic. The laser is also more precise and will help to avoid damaging healthy tooth structure, and it can also reduce the risk of post-operative complications. This procedure also results in a faster recovery time as there is less tissue trauma and less chance of infection.
