Pinhole® Gum Recession Surgery (PST) For Receding Gums


The revolutionary 'Chao Pinhole Surgical Technique' (PST) is a receding gum surgery for restoring receded gums is now available at CLDC. Restore receding gums quickly, with minimal discomfort and without the need for invasive and painful graft surgery.

Pinhole gum surgery is a treatment developed over the past decade in the USA by dentist and educator Dr John Chao (DDS).

This involves no scalpels and no stitches, so patients can expect only minimal pain or discomfort, bleeding and inflammation, and a much faster recovery than conventional gum recession surgery. This exciting new procedure is only performed by a handful of specially trained dentists around Australia, including Dr Nataniel Goldstein at the Cosmetic & Laser Dentistry Centre.

The benefits of the Chao Pinhole Surgical Technique

pinhole-shieldThere are many aesthetic and tooth preserving advantages in undergoing the PST gum recession treatment, including:

  • Superior aesthetic results
  • Less invasive surgery
  • Faster recovery time
  • No scalpels and no stitches

What are the typical results?

In around 90% of cases, the results of are comparable to that of a free connective tissue graft surgery, but is much less invasive with minimal post-operative pain symptoms.


What are the common causes of sudden gum recession?

  • Gum disease.
  • Aggressive or over-brushing.
  • Neglect of dental health.
  • Bruxism (clenching or grinding).
  • Natural ageing.
  • Hormones.
  • Smoking.
  • Piercings of the lips or mouth.
  • Genetics.
  • Recession caused by tooth loss and/or subsequent dental implants.

What is the alternative treatment for receding gums?

The majority of dental surgeons in Australia continue to restore receding gums with a 'gum grafting' surgery, which involves surgically excising a piece of the patient’s gum, usually from the roof of the mouth, and surgically grafting it to the area that has receded. This technique, while effective, is far more invasive and also does not provide the same aesthetic results as the considerably less invasive pinhole technique.

The pinhole surgical technique provides a predictable, minimally invasive, cost effective alternative to 'free-connective tissue grafting', with treatment results comparable to the traditional receding gum treatment methods.

Comparing the Pinhole Technique with a Traditional Gum Graft:


  Pinhole Surgical Technique Conventional Gum Grafting
Time Around 1 hour, multiple areas at once. Longer surgery,
Surgery Using specialised tools through a small pinhole entry point, the gingiva is loosened from the connective tissue and pulled over the receded area. Collagen strips are then implanted to promote healing and stability. A length of donor gum is excised from elsewhere in the mouth, and surgically placed under the receding gum area, then stitched back and left to heal.
Invasiveness Minimally invasive pinhole entry, requires no incisions or stitches in the gums. Considierably invasive.
Recovery Some minor discomfort for a number of weeks, easily managed with over-the-counter pain medication. Up to 1 year for complete recovery and healing.
Results Predictable aesthetic outcome similar to that of conventional gum grafting, with a 90% success rate. Leaves scarring at the donor site which may also be visible at the recipient area.
Cost This procedure is done in-chair at the practice, no general anaesthesia. Costs may include an anaesthetist, theatre fees, and costs for the surgery itself.
Potential complications Slight swelling or bleeding around the procedure site. Severe swelling, loosening of stitches, infection, uneven healing, scarring, tissue slouching on the upper arch.

Why consider the Pinhole Gum Recession Surgery?

Apart from the benefits mentioned above, when used in combination with other restorative treatments such as dental implants, a patient’s mouth can in some cases be completely restored to a state as close as possible to the natural, original beauty and function of healthy teeth and gums.

Many dental implant-based technologies include a prosthetic gumline or pink coloured material to blend in with the receded gum. Using the Chao Pinhole Surgical Technique, the gumline can in many cases be restored, giving a truly natural look and feel to a dental implant or implant bridge.


I have recession around my dental implant, bridge, or crown. Can the pinhole technique work for me?

Yes! The Chao Pinhole Surgical Technique can be used to successfully restore gingiva that has receded away from a prosthetic or dental implant.

What happens if I ignore my gum recession?

  • You may develop 'hypersensitivity' - sharp sudden pain from changes in temperature, or even brushing.
  • The gum recession may worsen.
  • Recession can eventually lead to exposed tooth roots, decays much more quickly, leading to cavities.
  • Worst case scenario: the tooth will fall out.
