Gum recession breakthrough treatments.


The Chao Pinhole® Surgical Technique (PST®) was patented invented by John Chao, D.D.S. It is a treatment for gum recession which is scalpel-free and suture-free.
A small hole is made in the gum tissue in the procedure where the gum tissue is loosened and guided over the recede part of the tooth during the procedure. Most patients also are pleasantly surprised by the instant cosmetic improvement. There are minimal post-operative symptoms (pain, bleeding and swelling) as there is no incision or suturing.
