Receding Gums? There's a Better Way.
Scalpel-Free. Suture-Free. Same-Day Results.
Dr. John Chao, DDS invented the Pinhole Surgical Technique® — a revolutionary, minimally invasive treatment for gum recession now adopted by over 4,000 dentists worldwide.


Revolutionary Treatment
What is Pinhole Gum Rejuvenation®?
Pinhole Gum Rejuvenation, also know as The Pinhole Surgical Technique® (PST®), invented and patented by Dr. John Chao, is a scalpel-free, suture-free procedure for treating gum recession. Using a tiny pinhole made with a needle, specially designed instruments gently reposition the gum tissue over the receded area — no cutting, no grafting, no stitches.
Most patients experience minimal discomfort and see immediate cosmetic improvement. Multiple teeth can be treated in a single visit.
