Pinhole Gum Rejuvenation®
The revolutionary, scalpel-free, suture-free treatment for gum recession — invented and patented by Dr. John Chao, DDS.
What is the Pinhole Surgical Technique®?
The Pinhole Surgical Technique® (PST®), also known as Pinhole Gum Rejuvenation®, is a minimally invasive procedure for treating gum recession. Invented and patented by Dr. John Chao, this revolutionary technique eliminates the need for scalpels, sutures, and palatal grafting.
The procedure involves making a small pinhole in the gum tissue using a specialized needle. Through this tiny opening, specially designed instruments gently loosen and reposition the gum tissue to cover the exposed root surfaces. Collagen strips are placed through the pinhole to stabilize the tissue.
Because there is no incision or suturing, patients experience minimal post-operative symptoms — including less pain, swelling, and bleeding compared to traditional gum grafting. Most patients also enjoy immediate cosmetic improvement.

What is Gum Recession?
Gum recession occurs when the gum tissue surrounding the teeth pulls back, exposing more of the tooth or its root. This can lead to tooth sensitivity, increased risk of decay, and eventual tooth loss if left untreated.
Common Causes
- Periodontal (gum) disease
- Aggressive brushing technique
- Genetics and thin gum tissue
- Teeth grinding (bruxism)
- Misaligned teeth or bite
- Tobacco use
Signs You May Need Treatment
- Teeth appear longer than normal
- Tooth sensitivity to hot or cold
- Visible tooth roots
- Notching at the gum line
- Loose teeth
- Changes in your bite
Don't wait until it's too late.
Gum recession is progressive. Early treatment with the Pinhole Technique can save your teeth and restore your smile.
