If your teeth look longer than they used to, or a tooth has become sensitive to cold along the gum line, that is gum recession. The traditional fix is a gum graft, which involves taking tissue from the roof of your mouth and stitching it into place.
The Pinhole Surgical Technique does the same job differently. No scalpel, no sutures, and no donor site. It is a less invasive alternative to traditional gum grafting and, for the right patient, a very effective treatment for receding gums.
What Pinhole Gum Surgery Is
The Pinhole Surgical Technique, often shortened to PST, was developed by Dr. John Chao and is a minimally invasive treatment for gum recession. It is trademarked as the Chao Pinhole Surgical Technique, and clinicians have to complete specific training through the Chao Pinhole Academy to perform it. Our periodontists are Chao Pinhole certified, which matters more than it sounds: the instruments are proprietary, and the technique is not something a practice can adopt informally.
The principle is simple. Rather than an invasive surgical approach that cuts the gum open and adds tissue, we make a small hole in the gum above the area of gum recession, use specialized instruments to loosen the gum tissue through it, and slide the existing gum tissue back down over the exposed tooth roots to correct gum recession. Collagen strips are inserted through the pinhole to hold the gum in its new position while it heals.
There are no incisions and nothing to stitch. The small hole closes on its own within a day or two.
How It Differs From A Gum Graft
This is the distinction that decides whether pinhole is right for you, and most pages describing the technique skip past it.
A gum graft adds new tissue. Pinhole moves the tissue you already have.
Traditional gum grafting takes a connective tissue graft from the palate, or uses donor tissue, and places it where the gum has receded. That adds thickness and volume. Unlike gum grafting, the pinhole procedure repositions the tissue you already have and adds none, which is why tissue grafts remain the answer in some cases.
| Pinhole (PST) | Connective tissue graft | |
|---|---|---|
| Incisions | None, one small pinhole | Yes, plus a donor site |
| Sutures | None | Yes |
| Roof of the mouth | Untouched | Usually the donor site |
| Adds tissue thickness | No | Yes |
| Multiple teeth in one visit | Straightforward | More limited |
| Recovery period | Usually 24 to 48 hours | One to two weeks |
| Long-term evidence | Shorter track record | Decades of published data |
Both are legitimate. Which one is right depends on your tissue, not on which sounds more appealing.
What Causes Gum Recession
- Aggressive tooth brushing, particularly with a hard brush
- Periodontal disease, which destroys the supporting tissue
- Thin gum tissue, which is largely inherited
- Grinding and clenching
- Orthodontic movement of teeth outside the bone
- Tobacco use
- Piercings that rub against the gum line
Poor oral hygiene is not usually the cause on its own, though it makes everything worse, and good hygiene protects the result of any gum treatment afterward.
A recession does not reverse on its own and tends to worsen. Left alone, exposed roots decay more easily, sensitivity worsens, and in advanced cases it contributes to tooth loss.
What Happens During The Procedure
- Local anesthesia. The area is numbed. Most patients need nothing stronger.
- The pinhole. A small hole is made in the gum above the teeth being treated, a few millimeters across.
- Loosening the tissue. Specialized instruments are passed through the pinhole to loosen the gum tissue from the underlying bone, allowing it to move.
- Repositioning. The gum is guided down over the exposed roots to the correct level.
- Collagen. Collagen strips are placed through the same pinhole to stabilize the tissue while it reattaches.
This surgical procedure typically takes one to two hours and can treat several teeth or an entire arch in a single visit, rather than one or two teeth at a time. That is one of the genuine advantages over grafting, where treating many teeth at once means a large donor site. Faster recovery is the other.
Who Is A Good Candidate
Pinhole works well where there is healthy gum tissue of reasonable thickness overlying the recession and the underlying bone is intact.
It suits patients who have recession across several teeth, who want to avoid a palatal donor site, who need a fast recovery, or who have declined a graft and left the recession untreated as a result.
Where it is not the right answer:
- Thin or insufficient gum tissue. Pinhole moves tissue rather than adding it. If there is not enough to work with, a graft is the correct procedure, and no amount of repositioning substitutes for adding volume.
- Active periodontal disease. This has to be treated first. More on that below.
- Significant bone loss around the tooth, where repositioning gum over a root with no bone support underneath will not hold.
- Heavy smoking, which affects healing and increases the chance of the tissue relapsing.
We will tell you which category you are in at the consultation, including when the honest answer is that a connective tissue graft would serve you better.
Does Pinhole Surgery Treat Gum Disease?
No, pinhole gum surgery is a treatment for gum recession, a soft-tissue and aesthetic problem. Gum disease is a bacterial infection destroying the attachment around the tooth. Covering an exposed root does nothing to address the active infection underneath.
If you have periodontal disease, that gets treated first, usually with scaling and root planing or LANAP. Once the disease is stable, we can treat gum recession. Doing it the other way round wastes the procedure and does nothing for your overall oral health.
Success Rate And How Long It Lasts
The four questions patients ask most are whether it works, how long it lasts, what the success rate is, and whether it is worth it. Here is the position we take.
Reported outcomes are good. Published case series show substantial root coverage maintained at follow-up, and patient satisfaction is consistently high, largely because recovery is much easier than with grafting.
What we will not do is quote a success rate as though it were settled. The technique was introduced in the mid-2000s, and the published evidence base is smaller and shorter-term than for connective tissue grafting, which has decades of data behind it. Some cases relapse, particularly where the tissue was thin to begin with or where the original cause has not changed.
That is not an argument against pinhole. It is an argument for choosing the procedure on the anatomy rather than on the marketing.
Recovery
Most patients return to normal activities the next day, which is the clearest difference from grafting.
- Mild swelling and tenderness for a day or two
- No sutures to remove and no palatal wound to protect
- Tooth sensitivity usually improves once the roots are covered
We’ll give you specific aftercare instructions for the first few days. Recovery time after minimally invasive surgery of this kind is measured in days rather than weeks, which is the main reason patients who declined a graft will accept this.
What Affects The Cost
The Pinhole Surgical Technique is generally priced per tooth or per area treated. What drives the total:
- How many teeth are being treated
- How severe the recession is
- Whether periodontal treatment is needed first
- Whether grafting is required alongside it in some sites
Insurance sometimes contributes where the recession is causing sensitivity or root decay rather than being purely cosmetic, and coverage varies by plan. We will review yours and let you know what applies before you commit to anything.
We’ll give you an exact cost during your consultation as part of your treatment plan.
Schedule A Consultation
If your gums have receded and you have been told a graft is the only option, it is worth a second look from a Chao Pinhole-certified periodontist. We will assess how much tissue you have to work with, tell you whether pinhole would hold, and be straight with you when a graft is the better choice.

Frequently Asked Questions
Is pinhole gum surgery painful? The procedure is done under local anesthesia, so you should not feel it. Afterward, most patients describe mild soreness rather than pain, and considerably less than they expected from a gum procedure.
How long does pinhole gum surgery last? Results are generally durable where the case was well selected, and the cause of the recession has been addressed. Relapse is more likely with thin tissue, continued aggressive brushing, or smoking.
Is pinhole gum surgery worth it? For the right case, yes, and the avoided donor site is a genuine benefit rather than a marketing point. For thin tissue, a graft gives a more predictable long-term result, and we would say so.
Do you need stitches after pinhole gum surgery? No. That is one of the defining features of the technique. The pinhole closes on its own.
How many teeth can be treated at once? Often a full arch in one visit, which is difficult with grafting due to the required donor site.
Can gum recession come back after treatment? It can, if the cause has not changed. Brushing technique, grinding, and smoking all matter afterward.
Who should perform the pinhole technique? A periodontist certified in the protocol. It requires proprietary instruments and formal training through the Chao Pinhole Academy, so it is worth asking any practice offering it whether they are certified. We are. Beyond that, the judgment in case selection matters more than the technique itself.
Is pinhole gum surgery available in New York and New Jersey? Yes. We treat gum recession with the Pinhole Surgical Technique across our Manhattan, Nutley, Long Island, and Bronxville offices.
