Low level laser therapy (LLLT) is a technique that uses various frequencies of light to stimulate cellular energy, which penetrates your nerves, cells and tissue to enhance healing, reduce pain and inflammation after dental procedures. LLLT has been used in dentistry to promote wound healing in surgical wounds, extraction sites, recurrent aphthous ulcerations, etc. LLLT is an effective treatment strategy for periodontal therapy and surgery. Photobiomodulation, a process mediated by low-level lasers, promotes additional benefits in the near term, speeds up the healing of bone and gingival tissue, and lessens the side effects of periodontal surgery.
