The Chao Pinhole Surgical Technique (PST) is a revolutionary new treatment for receding gums.  Our gums recede for a number of reasons including; over-enthusiastic brushing, teeth grinding, genetics, trauma, ageing and not cleaning your teeth properly.

Long in the tooth is a common description for receding gums because it makes your teeth look longer.pinhole surgical technique

Giginitive recession is another name for receding gums and severe cases lead to tooth loss, bleeding gums, bad breath and exposed tooth roots.

Receding gums are uncomfortable and also cause people to be self-conscious about their appearance. Your dentist will be able to determine if your gums are receding and the severity of the problem.

In minor gum recession, the dentist can prescribe treatments such as; antiseptic gel or mouthwash to treat the underlying cause.  In more severe cases your dentist will refer you to a specialist who is able to surgically treat the condition.


What Is The Pinhole Surgical Technique?

The Chao Pinhole Surgical Technique is rapidly replacing the traditional methods of repairing receding gum lines.  For many years soft tissue grafts were sutured to join to existing gum tissue as it healed. This method, although very successful, involves a lot of cutting and sewing and requires healing time. The Pinhole surgical technique is less invasive, more efficient and requires little recovery time.

Doctor Chao describes the pinhole surgical technique as a ‘suture-free procedure for correcting gum recession’.   Instead of cutting the gums a small incision in the gum allowing the insertion of special tools that loosen the gums. The instruments pull the gums over the part of the tooth where the recession is.  Results are almost instant and require very little healing time. Patients are immediately happy with the results. (Source:

Your whole mouth can have the pinhole surgical technique in one session while grafting involves a number of visits. Grafting is more painful than the pinhole surgical technique and requires a longer healing time.  In fact, the Pinhole Surgical Technique sounds too good to be true. Which introduces the question as to whether the results last or just wears off after a few years.


So What’s The Rub – Does PST Last?

The longevity of such a technique is difficult to prove until we assess the results many years after the procedure.  Dr Chao has always suggested that the treatment is permanent as long as patients follow a good dental hygiene routine and look after their mouths.  Evidence on his website in the form of patient testimonials suggests his prediction is correct. Two testimonials involve patients who were treated over nine years ago.

Doctor Chao expects the effects of the treatment to last a lifetime as long as the gums remain healthy and brushing is gentle. Ageing will naturally cause gums to recede a little otherwise the effect is long-lasting.  Initially, Doctor Chao was the only doctor able to carry out the procedure now dentists from all over the world are able to perform the procedure due to extensive training.

Doctor Shira and his team are able to perform the technique as a result of this training.
