LANAP Laser Gum Treatment: What to Know Before Choosing It

LANAP is a laser-based gum treatment that is intended to treat moderate-to-severe gum disease without the large tissue flaps and stitches of traditional gum surgery. Some early studies report pocket reduction and limited gum recession, but recovery varies and can include soreness. Professional organizations consider the evidence for laser-assisted periodontal therapy limited, and direct long-term comparisons with flap surgery are still lacking. LANAP should not be viewed as a proven replacement for traditional gum surgery. Treating gum disease matters well beyond your gums, including for future implants and for keeping your natural teeth.

How is LANAP different from traditional gum surgery?

Advanced gum disease (periodontitis) creates deep pockets between teeth and gums where bacteria and inflamed tissue collect. Traditional flap surgery lifts the gums away from the teeth so the roots can be cleaned directly, then repositions and stitches the tissue. That approach has a long track record, but it can leave the gums sitting lower and teeth looking longer. Recovery can also be uncomfortable.

LANAP uses a specific laser protocol that is intended to target diseased tissue inside the pocket while sparing healthy tissue. It is also paired with careful cleaning of the root surfaces. The goal is to reduce pocket depth, and the laser is proposed to support gum reattachment to the tooth with less disruption to the surrounding tissue. Evidence for that reattachment is limited and not all studies agree. Whether LANAP fits your situation depends on how far the disease has progressed, which a dentist determines with measurements and X-rays.

What does the research show so far?

As of September 2026, the published research on LANAP consists mostly of small clinical studies and reviews. A few themes stand out:

• A small case series reported that most treated sites reached healthy pocket depths during follow-up, with little gum recession and no tooth loss in that group.
• Recovery in that series was generally described as mild, though some patients used over-the-counter pain relievers in the first days afterward. Individual experiences vary.
• One small, preliminary comparison of LANAP with standard scaling and root planing reported better results for LANAP at one year. Not all studies agree, and other trials have compared LANAP with deep cleaning alone.
• Reviews of laser-assisted flap procedures suggest lasers may add modest benefits, but those reviews look at lasers combined with flap surgery, not LANAP alone.

What we can't say yet: Most LANAP studies are small, short-term, or lack a direct flap-surgery comparison group. Professional organizations have described the evidence for laser-based new attachment as limited and inconsistent. Larger, longer trials are needed before anyone can promise that laser and surgical results will be equivalent over ten or twenty years.

Why does treating gum disease matter beyond your gums?

Recent reviews of many studies have found that periodontitis is a significant risk indicator for problems around dental implants. Reviews link a history of gum disease with a higher risk of peri-implantitis, the infection and bone loss that can affect implants, and active, untreated gum disease appears to raise that risk further. The same body of research emphasizes controlling gum disease to a stable point before placing implants, and keeping up regular maintenance visits afterward.

There is also a bigger-picture reason to protect your natural teeth. Large, long-running studies in older adults have found that people with more missing teeth are more likely to develop cognitive decline or dementia later. These are observational studies, so they show an association, not proof that tooth loss causes memory problems. Factors like diet, overall health, and access to dental care likely play a role. Still, they add another reason to treat gum disease early and keep your own teeth as long as possible.

Is LANAP right for you, and what is the logistics from Redwood City?

LANAP is typically considered for people with moderate-to-severe periodontitis, often after an exam shows deep pockets, bleeding, or bone loss. It is not meant for everyone. Mild gum disease is often managed with deep cleaning, and some defects may still call for other approaches. Smoking, diabetes, and how well you clean at home all influence outcomes.

LANAP is a trademarked protocol that requires specific training and equipment. At Carlmont Dental Care, we offer periodontal evaluation and can discuss laser and traditional options with you, or coordinate with a periodontist when specialized care is needed. Depending on the practice, some cases are referred to a periodontist, which is appropriate when specialized care is needed.

Patients coming from Redwood City typically have a short drive to our Belmont office, depending on traffic, with routes such as El Camino Real, Alameda de las Pulgas, or 101 to Ralston Avenue. Travel times vary.

Common questions about LANAP

Local anesthesia is typically used. In the small studies available, recovery varied, and patients often reported some soreness and sensitivity in the days afterward. Everyone heals differently, and your dentist can explain what to expect for your case.

No. Gum disease is a chronic condition. Even after successful treatment, most patients need regular periodontal maintenance visits and good home care to keep results stable.

The investment varies with how many areas need treatment and how advanced the disease is. Coverage depends on your plan. We accept most PPO plans, but not HMO or DMO plans. After a consultation, you'll receive a written estimate. In-house membership plans start at $30 per month, and 0% APR financing through CareCredit or Proceed Finance may be available, subject to credit approval and the lender's terms.

Warning signs include bleeding gums, persistent bad breath, gums pulling away from teeth, and loose teeth. Gum disease can also be painless, so the reliable way to know is a periodontal exam with pocket measurements and X-rays.
