Benefits of Laser Gum Therapy to Remove Diseased Gum Tssue No general anesthetic is needed, as is sometimes required for other forms of dental surgery. Lasers can target the diseased areas precisely and accurately. Bleeding, pain and swelling are limited because periodontal laser therapy is less invasive than regular surgery. Recovery and healing times are shorter. If you think you are suffering from gum disease, ask your Dental Care at Pleasant Hill dentist about laser therapy.
