How the Pinhole Surgical Technique works

During the Chao Pinhole Surgical Technique™, a tiny needle is used to make a small hole in your gum tissue. Through this pinhole, we use special instruments to gently loosen the gum tissue to help expand and slide the gumline to cover the exposed root structure.

Frequently asked questions

What are the benefits?

The benefits of the Pinhole Surgical Technique™ include: Quicker recovery for the patient than traditional grafting Reduced discomfort for the patient after treatment Doesn't require sutures Doesn't require scalpels or invasive surgical tools Doesn't require taking donor tissue from the patient’s palate

What happens after treatment?

The entry site quickly heals and the pinhole is virtually undetectable the next day, with no downtime needed for healing. Some patients may experience mild swelling, which dissipates in a few days.

What happens during treatment?

During the Chao Pinhole Surgical Technique™, a tiny needle is used to make a small hole in your gum tissue. Through this pinhole, we use special instruments to gently loosen the gum tissue to help expand and slide the gumline to cover the exposed root structure.

Gum Grafting vs. Pinhole Surgical Technique

In contrast to traditional gum recession treatments which involve using donor or soft tissue grafts to rebuild the gum line and sutured in place, the Pinhole Surgical Technique™ offers a breath-through alternative to gum grafting. Suture-free procedures for treating gum recession involves creating a small pinhole with a needle in the gum line to gently loosen the tissue to glide it over the receding part of the tooth. Since this technique simply involves adjusting existing tissue, there are no grafts, no sutures and no incisions required.

How Much is Pinhole Surgical Technique?

The Chao Pinhole® Surgical Technique cost is comparable to traditional gum grafting procedures. In fact, the total cost can be less expensive because we can treat multiple teeth during a single treatment. We will work with your dental insurance and provide financing to help you get the care your need today.

What are the risks?

All surgical procedures carry the risk of bleeding, discomfort, and infection. The Chao Pinhole Surgical Technique® minimizes these risks, and you can further minimize them by choosing an outstanding doctor. Dr. Stanley Sun, who performs this procedure at our practice, is licensed by the creator of the technique.

Why patients love Dr. Stanley Sun

Jessica L.

I am a patient of Dr. Stanley Sun and he performed gum grafting surgery on me twice. The first time was with the tunnel grafting technique and the second time was with the newer Pinhole Surgical Technique. I prefer the Pinhole Surgical Technique over tunnel grafting as the recovery time was tremendously shorter.  I had it done on a Friday and was recovered by Monday. Also, my face did not swell up as much. The overall procedure went very smooth. Dr. Sun is very professional and I am pleased with his service.  I would like to take this opportunity to thank him for his excellent work. I would definitely recommend him and the Pinhole Surgical Technique to others. Thanks again!

"Dr. Sun was amazing! I went in a little anxious and nervous, but as usual they took care of me and were very informative. I walked out a little swollen but fully able to talk and felt great! They've called me to follow up a couple of times and I have to say it's been a couple of days since the procedure and I feel completely fine with no swelling or soreness. Great work and service!
