How Pinhole® works

Pinhole Gum Rejuvenation® is performed by making small holes 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 cutting or stitching, patients can expect minimal post-operative symptoms (pain, swelling and bleeding). Patients experience instant cosmetic results and are typically back to normal activities in 24 to 48 hours after the procedure.

John C. Chao, D.D.S. MAGD

Research Associate Professor, University at Buffalo, SUNY Adjunct Assistant Professor, Ostrow School of Dentistry USC
Dr. Chao’s involvement with the Post-Graduate Periodontics Program at the University of Buffalo, SUNY, speaks to the depth of his knowledge and experience in the scientific investigation of gum disease. As a Research Assistant Professor at this university, Dr. Chao is involved in a major study comparing the Pinhole Surgical Technique, his invention, to the standard treatment for gum recession called the Connective Tissue Graft. Dr. Chao will be one of the authors of this new study.
