Teeth that look longer than they used to, or sting when a cold drink touches them, are often the first sign of receding gums.

Pinhole gum surgery is one way to cover those exposed roots without taking gum tissue from somewhere else in your mouth. Instead of a graft, a periodontist gently loosens your own gum and moves it back over the root through one small hole. It is a specialist procedure, and not every practice offers it.

This guide covers what pinhole surgery treats and how the procedure runs step by step. It also explains recovery, the technique’s limits and what we charge for it.

Pinhole Gum Surgery: What Does It Actually Treat?

Pinhole gum surgery treats gum recession, where the gum has pulled back and left part of the root exposed.

Pinhole surgery is considered when:

• Roots are exposed. The gum has pulled back from one tooth or several, and the root shows.
• Teeth are sensitive. Cold drinks or brushing sting where the root is bare.
• Recession is mild to moderate. The published studies treated recession classed as Miller Class I and II, where the gum and bone between the teeth are still intact.
• Several teeth need treatment. One entry point can reach neighbouring teeth, so a number of them can be treated in the same visit.

At a consultation, our Specialist Periodontist checks whether your recession is the kind this technique suits. They measure how far your gums have receded and check the health of the surrounding tissue.

For more on what causes gum recession and how it progresses, read our receding gums treatment guide.

Pinhole Surgical Technique: The Procedure Step by Step

A periodontist carries out the pinhole surgical technique under local anaesthetic, following five steps. Our Specialist Periodontist was trained in the technique by the dentist who created it, and uses the special instruments designed for it.

The five steps run in this order:

1. Numbing. A local anaesthetic numbs the gum around the teeth being treated.
2. The opening. Your periodontist makes one small hole in the gum near the treated teeth.
3. Loosening. Fine instruments passed through the hole gently free the gum from the tissue beneath it, so it can move.
4. Moving the gum. Your periodontist slides the loosened gum over the exposed roots into its new position.
5. Holding it in place. Thin strips of collagen membrane are passed through the same hole and sit between the teeth. They support the gum, so no stitches are needed. Some clinicians use a membrane made from the patient’s own blood instead.

There is no flap of gum to lift, and the new gum line is visible as soon as the treatment ends. For more on the gum treatments we offer, see our gum treatment page.

Pinhole Technique vs Gum Graft: Why No Tissue Is Taken

The pinhole technique and a gum graft both cover exposed roots. The difference is where the covering gum comes from. In a traditional gingival graft, a surgeon takes gum tissue from a healthy area of your mouth, places it at the receding gum and closes the area with stitches. Pinhole surgery uses the gum you already have, so there is no second wound. It is sometimes called a pinhole gingival graft, even though no graft tissue is involved.

We offer gum grafts as well, so our Specialist Periodontist can explain how each option would work for your teeth at your consultation.

Disadvantages of Pinhole Gum Surgery: The Limits to Know

No technique suits everyone, and pinhole surgery has limits that are worth understanding before you decide. The published studies report good results, but they also show which cases the technique suits and who should carry it out.

The main limits are:

• Mild to moderate recession only. More advanced recession falls outside the cases the studies tested.
• Gum disease comes first. Active gum disease and inflammation are treated before surgery, so that the gums are healthy enough for the result to hold.
• Training matters. The pinhole surgical technique uses special instruments and takes time to master, so the clinician’s experience affects the outcome.
• Evidence is short-term. The two studies in this guide followed patients for 6 months, so they cannot show how the result holds up over the years that follow.

None of these limits makes the technique a poor choice. They explain why an assessment of your gums comes before any decision about treatment.

Pinhole Gum Procedure: How Long Do the Results Last?

The published figures are encouraging, but they cover a short period. In a study of 10 patients, root coverage averaged 98% at 3 months and 87% at 6 months. The number of patients with complete coverage fell from 9 to 6 over the same period. In another study, which treated 18 areas in 5 patients, coverage averaged 96.7% at 6 months. Neither followed patients for longer, so no one can say how long the result will last.

Note: These figures come from small studies of 5 and 10 patients. They show what the technique can achieve rather than what every patient can expect.

What to Remember Before Choosing Pinhole Treatment

Pinhole gum surgery is a gentler way to cover exposed roots than a gum graft, for the cases it suits.

What to keep in mind:

• It suits mild to moderate recession. An assessment shows whether your gums fall within that range.
• Your own gum is used. Nothing is taken from elsewhere in your mouth, and there are no stitches.
• Healing takes weeks. The tissue needs 4 to 8 weeks to settle.
• Coverage can reduce over time. It fell between 3 and 6 months in one study, so follow-up matters.
• Training matters. Ask who will carry out the treatment and how they learned the technique.

Gum that has receded does not grow back on its own, so a clear diagnosis is the best first step. A consultation shows how far your gums have receded, what may have caused it and whether pinhole surgery or another treatment suits you.

Our Specialist Periodontist can examine your gums, explain your options and confirm your fee. You can then decide on treatment with the full picture in front of you.
