Dr. Bynum Performs Chao Pinhole® Surgical Technique in Simpsonville, SC

Gum recession breakthrough treatment also known as Pinhole Gum Rejuvenation and Lunchtime Gum Lift


The Chao Pinhole® Surgical Technique (PST®), invented and patented by John Chao, D.D.S., is a scalpel-free, suture-free procedure for treating gum recession.

This procedure is performed by making a small hole with a needle in the gum tissue. Using specially designed instruments, the gum tissue is loosened and guided over the receded part of the tooth. Since there is no incision or suturing, patients can expect minimal post-operative symptoms (pain, swelling and bleeding). Most patients also are pleasantly surprised by the instant cosmetic improvement.

Frequently Asked Questions


What is gum recession?

Gum recession refers to the loss of gum tissue along the gumline. 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.

Why should gum recession by taken seriously?

When gum recession occurs, the root structure of the tooth becomes exposed. This means that tooth decay and other problems can affect the teeth along the gumline and beneath it. Since healthy gums are essential for a healthy mouth, getting gum recession treated is important for lasting dental wellness.

What is Chao Pinhole Surgical Technique (PST™)?

The Chao Pinhole Surgical Technique™ is a minimally invasive option for treating gum recession. Unlike traditional grafting techniques, PST™ is incision and suture free.

All of the tools and techniques used to perform the Chao Pinhole Surgical Technique™ were created by Dr. John Chao, who personally taught Dr. Bynum the process.

How does Chao Pinhole Surgical Technique (PST™) differ from traditional gum grafting?

Traditional gum recession treatments involve the use of donor tissue or soft tissue grafts in order to rebuild the gumline. This soft tissue would be sutured in place and would join with existing gum tissue as it healed. While this traditional grafting treatment is effective, comparable results with better patient experience can be achieved through the Chao Pinhole Surgical Technique™.

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

During the Chao Pinhole Surgical Technique™, a needle is used to make a small hole in the patient's existing gum tissue. Through this pinhole, special instruments are used to gently loosen the gum tissue. These tools help expand and slide the gumline to cover the exposed root structure.

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

What are the benefits of Chao Pinhole Surgical Technique (PST™)?

The benefits of the Chao Pinhole Surgical Technique™ are many:

  • Less Discomfort for the patient after treatment.
  • Faster recovery for the patient than traditional grafting.
  • No need for uncomfortable sutures.
  • No need for scalpels or invasive surgical tools.
  • No need to take donor tissue from the patients palate.
  • Excellent, natural-looking, long-lasting results.

Meet Dr. Matt

Dr. Matt Bynum originally from Southern California where he earned my undergraduate degree from The University of California, San Diego. From there he left the beaches of sunny Southern California and headed to the Midwest for a change in scenery and culture. There Dr. Matt earned his dental degree from The University of Iowa, College of Dentistry and has been practicing dentistry now for over 14 years.

Bynum Aesthetic Dentistry opened its doors in January 1998. For over 12 years they have been providing individualized, high-tech, high-touch, quality cosmetic, aesthetic and general dentistry to the Greenville community and surrounding areas. Bynum Aesthetic Dentistry takes pride in the fact their our clientele reaches beyond the Greenville area and into many states throughout the US and also into countries beyond our borders. The team is truly blessed and honored to care for so many people who are wanting or are ready for a change. Not just in their appearance, but in their care and their surroundings.

Dr. Matt has been extremely fortunate in his dental career to have been exposed to the very latest in materials and procedures while both learning and teaching at the world's premier post-graduate institution, The Las Vegas Institute for Advanced Dental Studies or what dental professionals and people across the world know as LVI. For about 10 years now, he has been a featured speaker and clinical instructor, teaching progressive dental concepts and procedures to dentists and dental offices all over the world. Aside from the hands-on clinical teaching and instruction he gives, he also does quite a bit of public speaking on topics ranging from clinical excellence and restorative dentistry to practice management/motivation and neuromuscular dentistry/occlusion to both dentists and dental professionals.

He is the co-director and co-founder of the "Achieving Extreme Success" seminar series where entire dental offices from around the globe come to train and learn about the inner workings of a successful dental practice. Together with his lecture partner and co-author, Dr. Art Mowery, and their amazing teams, they serve to teach dental offices the art of changing the dental experience for both patients and professionals alike. Dr. Matt is a featured author for many dental publications which are distributed all over the world, and continue to serve as a clinical evaluator and consultant to a number of dental manufacturers around the globe in the area of product development and clinical testing of dental materials.

In early 2008, Dr. Matt accomplished a long time goal and dream of publishing a book! The Boomerang Effect was written with success principles and concepts from the years and experience of both personal and professional development. While the book was initially intended for the dental profession, it has spread beyond the profession and into the hands of those who seek to improve and develop themselves. The book is a universal blueprint for virtually any job or profession out there and applies to so much more of life than teeth that it is being well received by people of all walks of life. His next project is to re-write and release a new book to the public chalked full of self-help and inspirational messaging, so look for it coming soon!

Dr. Matt is a long standing member and lecturer of the American Academy of Cosmetic Dentistry (AACD); the International Association of Comprehensive Aesthetics (IACA); the American Dental Association (ADA); and the South Carolina Dental Association (SCDA).

While he loves this profession of dentistry, his life "on the outside" consists of spending time with his wife and business partner, Dr. Ann Bynum and their three sons: Matthew, Luke and John. Coaching his boys in baseball, basketball and watching them do karate are all things Dr. Matt and Ann enjoy with the boys. Together they love anything that involves water and love heading to the lake on weekends. They also enjoy water skiing and wake boarding, snow skiing and anything involving Mickey Mouse (well, Ann and the kids do!). With the push of friends and Ann, he has recently come into the world of triathlon and endurance sports and is enjoying the training and physical results from that training. He loves to travel, enjoys fine dining experiences, and loves drinking and collecting fine wine.
