LANAP Laser Gum Treatment for San Mateo, CA Patients

LANAP (Laser-Assisted New Attachment Procedure) is a flap-free way to treat moderate-to-severe gum disease using a specific pulsed dental laser instead of a scalpel and stitches. Recent 2024–2025 reviews suggest LANAP can match traditional gum surgery for clinical attachment gain while producing less post-operative pain, less swelling, and less gum recession in many patients. For San Mateo families who want fewer post-op restrictions and a single in-house team handling the work, it is worth understanding how the procedure works and where the evidence is still maturing.

What is LANAP, and how is it different from traditional gum surgery?

Traditional periodontal surgery (often called osseous or flap surgery) involves cutting and folding back the gum tissue, cleaning the tooth root and bone underneath, then suturing the gum back into place. It works, and it has decades of long-term outcome data behind it. The trade-off is real swelling, sutures, dietary restrictions, and a meaningful chance of permanent gum recession that can leave teeth looking longer and feeling more sensitive to cold.

LANAP uses a free-running pulsed Nd:YAG laser (1064 nm wavelength) developed specifically for periodontal regeneration. The laser is threaded along the inside lining of each gum pocket where it selectively removes diseased tissue and reduces the bacteria that drive bone loss, while leaving the healthy outer gum largely intact. The tooth root is then cleaned with ultrasonic instruments, and a second laser pass forms a stable fibrin seal at the bottom of the pocket. There is no scalpel cut, no flap reflection, and typically no sutures. The U.S. FDA cleared the LANAP protocol in 2016 for language describing true periodontal regeneration — the formation of new cementum, periodontal ligament, and alveolar bone — when performed with the specific laser and protocol it was studied with.

What does recent research actually show?

This is where it pays to be careful. The 2024 and 2025 literature is encouraging but not unanimous, and we always want San Mateo patients to know exactly what the evidence does and does not say.

• Pocket depth and attachment gain: Recent randomized trials and a 2024 systematic review found that adding LANAP to scaling and root planing produces statistically significant reductions in probing depth and gains in clinical attachment compared to scaling and root planing alone — most clearly in deeper pockets (7 mm and beyond).
• Compared to traditional flap surgery: Where direct comparisons exist, LANAP appears comparable on long-term pocket depth and attachment outcomes, with the consistent advantage of less post-operative discomfort and less measurable gum recession.
• Healing experience: Across studies, patients report less bleeding, less swelling, and a faster return to normal eating and activity. Many people walk out without sutures.
• What is still maturing: The LANAP evidence base is smaller than the multi-decade body of work behind flap surgery. Some professional bodies — including a 2018 American Academy of Periodontology statement and the European Federation of Periodontology — have noted that laser adjuncts as a category show only modest added benefit over conventional treatment, and that the strongest LANAP claims rest on protocol-specific data. In plain English: results in published trials look promising and consistent, but long-term real-world data is still being collected.

Who is — and isn't — a good LANAP candidate?

LANAP is most often considered for adults with moderate to severe periodontitis whose pockets have not responded fully to deep cleaning (scaling and root planing) alone, or who would otherwise be referred for traditional gum surgery. It is also a reasonable option for patients on blood thinners, patients with health conditions that complicate sutured surgery, and patients who are anxious about scalpel procedures.

It is not the right tool for every case. Severe bone loss patterns that need physical recontouring, defects that require bone grafting, or pockets adjacent to failing restorations may still call for traditional flap surgery or a combined approach. The honest answer for any individual mouth comes from an exam, periodontal charting, and X-rays — not from a website.

What the visit looks like for San Mateo patients

Carlmont Dental Care sits just over the Belmont line, a short hop from San Mateo neighborhoods like Hillsdale, Baywood, and Beresford — roughly a 12–20 minute drive south on El Camino Real or via 101 to the Ralston Avenue exit. Treatment is typically split into two sessions, each covering half of the mouth, so you keep one side fully functional for eating while the other heals. Numbing is local. Most patients are back to a soft-food routine within a day or two and back to regular meals within a week. We then see you for follow-up visits to monitor pocket depths over the coming months.

A meaningful patient-side benefit in our area: many general practices in San Mateo County refer LANAP cases out, which adds visits, paperwork, and a new clinical team mid-treatment. Having the periodontal evaluation, the laser treatment, and the long-term maintenance under one roof in Belmont keeps your records, X-rays, and hygiene plan continuous.

Common questions about LANAP laser gum treatment

Q: Does LANAP hurt?

The procedure is done under local anesthesia, so you should not feel pain during treatment. Most patients report markedly less post-op soreness than they expected — closer to a deep cleaning than to traditional gum surgery in the published literature and in our chair-side experience.

Q: How long does recovery take?

Most San Mateo patients are back to work the next day. We ask you to stick to softer foods for several days, avoid using a straw for the first 24 hours, and skip vigorous flossing in the treated area while the seal matures. Full tissue maturation continues over several months.

Q: Will my gums look different afterward?

One of the main reasons patients choose LANAP is to limit visible gum recession. Compared to flap surgery, LANAP tends to preserve more of the outer gum margin, so teeth are less likely to look longer afterward — though results vary with anatomy and how advanced the disease was at the start.

Q: How much does LANAP cost, and is it covered?

Investment varies by how many quadrants need treatment, the severity of bone loss, and what supporting care (deep cleanings, maintenance, occlusal adjustment) the case requires. Carlmont Dental Care is in-network with most major PPOs (Delta Dental PPO, Aetna, MetLife, Cigna, Guardian, Ameritas, Blue Cross, Principal, Sun Life, Humana, United Concordia, GEHA) and we will give you a written estimate with your benefits applied. For patients without periodontal coverage, our in-house membership plans start at $30/month, and 0% APR financing through CareCredit and Proceed Finance is available.

Q: Is LANAP a one-time fix?

No periodontal treatment — laser or surgical — is a cure. Gum disease is a chronic condition, and long-term success depends on consistent maintenance cleanings (usually every three to four months at first), good home care, and managing risk factors like smoking and diabetes.

If you are weighing LANAP versus traditional gum surgery, the best next step is a periodontal evaluation so the conversation is grounded in your actual pocket depths, bone levels, and goals.
