How Laser Periodontal Therapy Treats Gum Disease

Medically Reviewed by Dr. David Peto on September 9, 2026

Laser periodontal therapy treats gum disease by using a focused laser to remove infected tissue and bacteria from around the teeth while leaving healthy gum tissue intact, an approach that typically means less bleeding, less discomfort, and a faster recovery than traditional gum surgery. This makes it a preferred option for many patients dealing with gingivitis or early to moderate periodontitis who want an effective, minimally invasive alternative to a scalpel-based procedure.

At Advanced Periodontics of N.J., our team offers laser periodontal therapy as part of a broader approach to gum disease treatment. We evaluate each case individually to determine whether laser therapy, traditional scaling and root planing, or a combination of approaches will produce the best long-term result for your specific stage of disease.

How Laser Periodontal Therapy Works

During treatment, a specialized laser targets and removes diseased tissue and bacteria from the periodontal pockets, the small gaps that form between the gum and tooth once disease has progressed. Because the laser can distinguish diseased tissue from healthy tissue with precision, it minimizes damage to the surrounding gum, which reduces bleeding during the procedure and supports faster healing afterward. The laser can also help reshape the gumline and reduce pocket depth, both of which make future maintenance easier.

What the Evidence Shows

Laser-assisted periodontal treatment, often referred to by the protocol name LANAP, has been studied in clinical settings for its effect on pocket depth and clinical attachment levels. A retrospective case series published on PubMed Central following patients with chronic periodontitis found measurable improvement in periodontal pocket depth one year after laser treatment. Research comparing laser therapy to scaling and root planing alone has also pointed to faster healing and reduced bacterial load immediately following treatment, supporting its use as an effective option for moderate to advanced gum disease.

What to Expect During Treatment

A laser periodontal therapy session generally follows a consistent sequence. Your periodontist starts with a thorough examination, including imaging to assess how far the disease has progressed. The laser is then used to remove infected tissue and bacteria from the periodontal pockets, and an antimicrobial solution may be applied to further reduce bacteria in the treated area. Most patients tolerate the procedure well and can return to normal activities within a short period, though your periodontist will provide specific aftercare instructions and may schedule follow-up visits to monitor healing.

Laser Therapy Compared to Traditional Gum Surgery

Traditional gum surgery typically involves incisions, sutures, and a longer recovery window. Laser periodontal therapy was developed as a less invasive alternative for many of the same indications, with several advantages patients tend to notice:

• Reduced bleeding: The laser’s coagulating effect limits bleeding during the procedure.
• Faster recovery: Less trauma to surrounding tissue typically means a quicker return to daily activities.
• Greater precision: The laser targets diseased tissue while preserving more of the healthy gum around it.
• Less discomfort: Reduced cutting and suturing generally means a more comfortable experience overall.

Laser therapy is not the right fit for every case, particularly very advanced disease with significant bone loss, which is why an individualized comparison of treatment options is part of every consultation.

Who Is a Good Candidate for Laser Periodontal Therapy

Patients with gingivitis or mild to moderate periodontitis are often good candidates for laser therapy, particularly those looking to avoid the longer recovery associated with traditional surgery. Patients with more advanced bone loss may still benefit from laser treatment as part of a broader plan that includes bone regeneration procedures. A periodontal evaluation, including pocket depth measurements and imaging, is the only reliable way to determine which approach fits your case.

Advanced, Evidence-Based Gum Disease Care

Dr. Matei and Dr. Peto stay current on periodontal laser technology and technique, applying it selectively based on what the clinical evidence and each patient’s specific presentation support, rather than defaulting to one treatment for every case. Our goal is to match the right protocol to your stage of disease so treatment is effective the first time.

If gum disease has been affecting your comfort or oral health, laser periodontal therapy may be a treatment option worth discussing. Contact our office to schedule a consultation and learn more about which approach is right for you.
