Pinhole Gum Surgery FAQ

What is Pinhole Gum Surgery?

Pinhole Gum Surgery — clinically known as the Chao Pinhole Surgical Technique (CPST) or Pinhole Surgical Technique (PST), developed and patented by Dr. John Chao, DDS — is a minimally invasive periodontal procedure for treating gum recession. The dentist creates a single 2–3 mm entry point in the existing gum tissue and uses specialized instruments called Trans-Mucosal Papillae Elevators to loosen and glide the gumline down to cover exposed root surfaces, without harvesting donor tissue.

How is Pinhole Gum Surgery different from gum grafting?

Traditional grafting — such as a connective-tissue graft or free gingival graft — requires a scalpel incision at the treatment site and typically a second incision at a donor site (usually the palate) to harvest tissue, followed by sutures. CPST uses one 2–3 mm pinhole access point and the Trans-Mucosal Papillae Elevator instruments to reposition the patient’s own existing tissue, eliminating donor-site harvesting and, in most cases, sutures entirely.

Does the procedure hurt?

The treatment area is numbed with local anesthesia before the entry point is made. Because there’s no scalpel incision or suturing, most patients report only mild tenderness in the 24–48 hours afterward, typically manageable with an over-the-counter anti-inflammatory such as ibuprofen.

Are stitches required?

No. CPST is a suture-free technique in the majority of cases. After the gum tissue is repositioned over the exposed root, strips of bioresorbable collagen membrane are placed through the entry point to stabilize the tissue — the collagen dissolves on its own and also stimulates the body’s own collagen production, so there’s no separate visit for suture removal.

How long does recovery take?

Most patients resume normal daily activities within 24–48 hours. Initial soft-tissue healing over the entry point occurs within days, and full stabilization of the repositioned gum tissue continues over the following weeks.

Can several teeth be treated at once?

Yes. Because the technique doesn’t require donor-site harvesting, a single session can often address multiple adjacent teeth — and in many published cases, a full arch — in one visit rather than requiring separate grafting procedures per site.

Is Pinhole Gum Surgery permanent?

Outcomes have been tracked in peer-reviewed follow-up: Dr. Chao’s original 2012 study in the International Journal of Periodontics & Restorative Dentistry followed 43 patients across 121 recession sites (mean initial recession of 3.4 ± 1.0 mm) and reported complete root coverage in 81.2% of Miller Class I and II sites, with 94% mean defect coverage. A 14.5-year long-term follow-up published in the same journal found sustained complete root coverage in 77.9% of those sites, with 86.6% mean root coverage maintained. Long-term stability still depends on good oral hygiene, regular periodontal maintenance, and managing contributing factors like aggressive brushing or bruxism.

Who is a good candidate?

Candidates are typically patients with Miller Class I, II, or III gum recession and adequate remaining attached gingiva. A clinical exam — including measurement of recession depth and gum tissue thickness — determines whether CPST or a different periodontal approach is appropriate.

Will insurance cover Pinhole Gum Surgery?

Coverage varies by plan and is often billed under periodontal soft-tissue procedure codes rather than a graft-specific code. Our team can review your specific benefits and out-of-pocket costs before treatment.

How do I get started?

Schedule a consultation for a periodontal exam, including recession measurement and Miller classification, to determine whether Pinhole Gum Surgery is the right treatment for your gumline.
