Here at Affinity Dental Care, we provide the Chao Pinhole Surgical Technique™, a minimally invasive option for treating gum recession.



Instant results, no incision, no sutures, no grafting!

What is gum recession?

Gum recession refers to the loss of gum tissue along the gum line. This can occur as a result of periodontal disease* (gingivitis, periodontitis, advanced periodontitis), the natural aging process, or abrasive habits when it comes to brushing the teeth.


Peter Workman is one of the first dentists in the UK to deliver Chao Pin.

Why Pinhole Surgical Technique™ (PST™) is a great alternative to traditional grafting?

• There is less discomfort for the patient after treatment
• Patients experience a faster recovery
• No need for uncomfortable sutures
• No need for scalpels


All of the tools and techniques used to perform the Pinhole Surgical Technique™ were created by Dr.John Chao, who trained Peter Workman in Los Angeles in January 2014.

How is Pinhole Surgical Technique™ (PST™) performed?

During the Pinhole Surgical Technique™, a tiny needle is used to make a very small hole in the patient’s existing gum tissue. Through this pinhole, special PST™ proprietary instruments are used to gently loosen the gum tissue. These tools help slide and reposition the gum line to cover the exposed root structure.

There are no grafts, no sutures, and no incisions needed with the Pinhole Surgical Technique™. It simply involves the adjustment of the existing tissue.

An enhanced PST™ is achieved by utilizing Platelet Rich Fibrin (L-PRF). Simply put, your blood is taken chair-side from a vein in your arm by Dr. Workman himself. In about ten minutes, the blood is prepared and processed with absolutely NO CHEMICALS, and it is ready for immediate use to help HEAL YOU. L-PRF is a revolutionary leap forward in dental healing. 

The PRF plug that is created contains your own growth factors, growth proteins, healing platelet cytokines, and the all-important regenerative stem cells. The L-PRF becomes your own dynamic super biomaterial to biologically stimulate your Pinhole soft tissue gum lift repair and regeneration, and to aid and accelerate wound healing.

There are only about 1500 dentists worldwide who can perform and are certified in the Pinhole Surgical Technique®, and only a very small fraction of them like Dr Peter Workman utilize L-PRF to achieve even greater results.
