LANAP, or Laser Assisted New Attachment Procedure, is a form of periodontal therapy used to treat periodontitis. Unlike traditional surgeries, which involve the removal of both diseased and healthy gum tissues, LANAP specifically targets infected areas of the gums – leaving healthy tissues behind. LANAP works using the Periolase® laser, which is FDA approved for periodontal treatment. This flexible laser emits energy at varying pulsating frequencies, effectively removing periodontal bacteria and infection, and facilitating the regeneration of the gums in areas where they have pulled away and recessed from the teeth.


LASER Assisted New Attachment Procedure (LANAP): Steps


A. Perio probe indicates excessive pocket depth and bone loss.

B. LASER radiation vaporizes bacteria, diseased tissue, pathologic proteins, and alerts the practitioner to the presence of tartar.

C. Ultrasonic scaler and specialized hand instruments are used to remove root surface accretions.

D. LASER finishes debriding and disinfecting pocket, and aids in hemostasis (clot, “band-aid” formation)

E. Pressure placed on gum tissue against the root surface to allow fibrin clot stabilization and promote re-attachment of gum tissue to the root surface.

F. Occlusal trauma is eliminated with bite adjustment.

G. New, healthy gum attachment achieved, with reduction of gum pockets.


Did you know…

that LANAP periodontal treatments have many advantages over traditional surgery? In addition to only targeting diseased tissues, LANAP features:

  • Rapid recovery
  • Minimal discomfort
  • Decreased bleeding
  • Selective removal of infected diseased tissue while sparing healthy tissue

Frequently Asked Questions

Am I a candidate for LANAP?

Patients who can benefit from LANAP have been diagnosed with periodontal disease with pocket depths between 5 and 6 millimeters. You may also benefit from LANAP if you have advanced periodontal pockets that are inoperable or that have become infected again despite a previous periodontal treatment. For more information about LANAP and whether it is right for you, schedule a periodontal consultation with our office today.

What should I expect during LANAP treatment?

Patients undergoing LANAP in Sunnyvale are made comfortable using a local anesthetic.  The option of sedation is also available for your comfort. Your periodontist will use a laser to gently removed diseased gum tissues from the pockets surrounding your teeth. After the infection is eliminated, your teeth will be cleaned, and the laser will be used once more to help your gums form healing clots around your teeth.

What should I expect after undergoing LANAP?

If you are like most patients, you’ll experience less swelling and discomfort than you would with traditional gum surgery, and your gums will bleed less following the procedure. You will be given special instructions for keeping the treatment site clean and free of debris; and you may need to follow a special diet in the days following your procedure. Because the clots are sensitive in the first week following LANAP treatment, you’ll also need to avoid brushing your gum line for the first several days after your procedure.
