LANAP Laser Gum Surgery: What to Expect Before, During, and After

LANAP is an FDA-cleared laser treatment for moderate to advanced gum disease that uses a thin fiber-optic tip — not a scalpel — to clean infected tissue and bacteria from beneath the gumline. Most patients report less swelling and bleeding than they expected, return to normal activities within a day or two, and follow a short soft-food window while the gums seal and heal. The procedure is performed under local anesthetic, usually treating one side of the mouth per visit.

How LANAP Differs From Traditional Gum Surgery

Conventional periodontal flap surgery treats deep gum pockets by cutting the gum away from the tooth, accessing the root surface, and stitching the tissue back into place. LANAP — short for Laser-Assisted New Attachment Procedure — takes a different path. A pulsed dental laser, tuned to a wavelength that targets pigmented diseased tissue and bacteria, is slipped between the gum and the tooth. The laser vaporizes inflamed tissue while sparing healthy gum, and a second pass creates a stable fibrin seal at the top of the pocket without any sutures.

Because the gum is never cut away from the bone, there is typically far less tissue recession after healing — an important consideration for patients worried about how their smile will look. Published clinical studies have shown the vast majority of treated pockets shrinking to healthy depths within a year, with mean recession of roughly a tenth of a millimeter.

Before Your LANAP Appointment

The work begins well before the laser is ever turned on. At Carlmont Dental Care in Belmont, your visit starts with a periodontal evaluation: pocket-depth charting around each tooth, digital x-rays to assess bone level, and a discussion of risk factors like smoking, diabetes, or family history of gum disease. Dr. Nancy Jiang, Dr. Amanda Lee, or Dr. Michael Chen will review whether LANAP is the right fit, or whether non-surgical scaling and root planing should come first.

A few practical reminders for the day of your procedure:

• Eat a normal meal beforehand; you will be on softer foods for several days afterward.
• Share your full medication list, especially blood thinners and supplements.
• Plan a quiet evening at home while the local anesthetic wears off.
• If you smoke, even a short pause before treatment supports better healing.

What Happens During the Procedure

After local anesthetic takes effect, treatment is usually completed in one to two hours per side. Most patients have one half of the mouth treated at a time and return about a week later for the other side.

The protocol follows a clear sequence:

1. A thin laser fiber — roughly the thickness of three human hairs — is gently placed between the gum and the tooth.
2. A first laser pass removes diseased pocket lining and disinfects the area.
3. Specialized ultrasonic instruments clean tartar and biofilm from the root surface.
4. A second laser pass forms a stable seal of blood and fibrin at the top of the pocket — the body's natural bandage.
5. The gum is pressed gently against the cleaned root, and your bite is adjusted so the healing teeth are not bumped during chewing.

No scalpel cuts, no stitches, no surgical packing. Many patients describe the appointment as more comfortable than the deep cleanings that preceded their diagnosis.

Recovery, Diet, and Healing Timeline

The first 24 to 48 hours bring mild soreness and possibly a small amount of overnight oozing — both are normal. Over-the-counter ibuprofen handles discomfort for most people. Practical guidelines we share with patients:

• Days 1–3: liquids and very soft foods — smoothies, broth-based soups, yogurt, protein shakes, blended oatmeal.
• Days 4–7: soft, easy-to-chew options like eggs, mashed potatoes, soft fish, and well-cooked pasta.
• Avoid hot, crunchy, spicy, or seedy foods that can disturb the seal.
• Skip vigorous brushing or flossing in the treated area at first; use the rinse we prescribe.
• No probing of the gums by anyone — including hygienists elsewhere — for the next 6 to 12 months while a new attachment forms.

Follow-up visits are typically scheduled at one week, one month, and then every three months through the first year so we can monitor healing and reinforce home-care habits.

Common Questions About LANAP

Q: Will I be asleep during LANAP?

No. LANAP is performed under local anesthesia, similar to a filling. If dental anxiety is a concern, ask about additional comfort options at your consultation.

Q: How soon can I go back to work?

Most patients return to a desk job the next day. Plan a lighter evening on the day of treatment while the numbness wears off and the clot stabilizes.

Q: Does LANAP replace daily home care?

It does not. Gum disease is driven by the bacteria around teeth every day, so brushing, flossing, and regular maintenance cleanings remain essential to keep the result stable long term.

Q: Is LANAP covered by insurance?

Most PPO plans we accept — including Delta Dental PPO, Aetna, Cigna, MetLife, and Guardian — cover medically necessary periodontal therapy, though the exact benefit varies by plan. We provide a written estimate after your consultation, and we also offer in-house membership plans starting at $30 per month and 0% APR financing through CareCredit and Proceed Finance.

Q: Who is not a good candidate?

Patients with very advanced bone loss, certain implant complications, or specific medical conditions may do better with another approach. A thorough exam is the only way to know for sure.

If your gums bleed when you brush, feel tender, or your dentist has mentioned deep pockets or bone loss, a periodontal consultation is a sensible next step.
