Laser Therapy

Laser-Assisted New Attachment Procedure (LANAP™) is a new therapy that allows for the effective treatment of periodontal disease with no removal of tissue.


LANAP™ is a gentle, conservative, non-invasive method of treating gum disease without cutting, suturing or removing tissue. Using a precision laser, Dr. Yu is able to kill up to 99% of the disease causing bacteria in the periodontal pockets. Because there is no defense against the laser, the bacteria cannot adapt and avoid elimination as with anti-biotic treatment.

There is no cutting or suturing as with traditional methods of treating periodontal disease. This provides a fast, virtually pain free procedure with that effectively treats periodontal disease.

Additionally, the precision of the laser allows Dr. Yu to avoid removing significant tissue. This allows for a faster recovery and minimal loss of tooth and bone structure after the procedure.

The Consequences of Periodontal Disease

Periodontal disease is the leading cause of tooth loss in adults. In its advanced stages the gums can become red and tender. They can also bleed when you brush your teeth. Many people also experience bad breath and an unpleasant taste.

Unchecked, periodontal disease becomes much more serious and deep pockets of bacteria develop. This bacteria eats away at the jawbone which supports your teeth. Periodontal bacteria also enter the blood stream and contribute to many other medical problems. Without treatment, the periodontal pockets deepen, resulting in tooth loss.

The purpose of periodontal treatment is to remove periodontal bacteria from the periodontal tissues and allow the area to heal. Until recently, bacterial removal entailed surgery, sutures and a much longer recovery period. Dr. Yu offers Laser Assisted New Attachment Procedure (LANAP™) as a patient-friendly and minimally-invasive alternative.

The Procedure

Because your resistance to disease is affected by many factors, we will begin your first visit with a review of your dental and medical histories. This is followed by a thorough periodontal examination of your mouth and discussion of findings and treatment options. Dr. Yu and staff will take special care to make sure that all your questions are answered concerning the treatment and go over any financial questions you may have. 

On your treatment appointment, a small laser fiber is inserted between the tooth and the gum and the bacterial infection is removed. You can expect to be prescribed an antibiotic along with pain medication, and most patients feel fine returning to work the very next day. Dr Yu and his staff will give you specific instructions on home care following your appointment and you will return to the office in 7-10 days for a post operative appointment. 

If your general dentist has recommended that you have Laser Therapy please contact us and we will be happy to schedule an appointment for you!
