A Paradigm Shift in Gum Therapy: Chao Pinhole Surgical Technique

My patients tend to be inquisitive people, and I get asked many questions. I love questions, and some of my favorites ask about what the latest and greatest discoveries are in the world of dentistry. I would like to share with you one breakthrough in gum rejuvenation therapy that is making waves in the medical world and could substantially impact some of my patients: the Chao Pinhole® Surgical Technique. 

The technique is a revolutionary way for dentists to provide gum rejuvenation therapy to patients, offering fast treatments and minimal discomfort. It is unique in gum rejuvenation therapy, as rather than grafting gum tissue from location to another, the doctor will use a special tool to move nearby gum tissue into better positions without the need for cutting or stitching gum grafts.

The procedure is designed to support healthy gums and give patients an easy way to improve the cosmetic appearance of their smiles. With minimally invasive techniques and single treatment procedures, the Chao Pinhole Surgical Technique is paving the way for new dentistry practices that support the health, confidence, and well-being of patients across the world.

What Does the Treatment Do?

At its core, the pinhole surgical technique was created by Dr. John Chao, DDS, MAGD, to give patients more options for improving their gum lines that don’t involve invasive grafts or prolonged healing periods.

The treatment is primarily used for correcting receding gum tissue. This can be caused by a variety of reasons:

How Does It Work?

  1. With the Chao Pinhole technique, the doctor uses a special tool to create a tiny hole in the gums.

  2. Through this aperture, he/she will loosen the gum attachments from the root tissue and will gently shift it in the desired shape. The elastic collagen present in our gum tissue makes this process simple and effective without the need to take tissue grafts from other gum areas.

  3. After repositioning the gum tissue, collagen strips are added to the site of the recession. These strips help ensure that the rejuvenated gums stay in the proper position. Despite the need to create an opening in the gums to insert the tool and loosen the gum attachments from within, the pinhole opening heals quickly and produces nearly instant results—along with high patient satisfaction.

Treatment Benefits

Before the Chao Pinhole Surgical Technique, patients had few options for gum skin grafting therapies. Traditional gum grafts are effective at improving gum recession, but bring noticeable discomfort to the patient and take a long time to heal. Traditional gum grafting requires doctors to make multiple incisions in the mouth, both to remove the graft tissue from the roof of the mouth as well as opening the recessed gum line to insert the graft. This complexity creates extensive healing periods and discomfort. Other options, like placing fillings over the exposed root, are temporary and will usually require further treatments down the line.

The Pinhole Advantage


The Chao Pinhole gum rejuvenation therapy is a groundbreaking option for gum recession therapy. The idea was born of Dr. Chao’s realization that patients had few good options for gum rejuvenation, and sought to develop a new system that streamlined the process. For patients seeking comfortable ways to restore their gum lines and confidence in their smiles, the Chao Pinhole Surgical Technique may be the answer.
