For patients considering gum-recession treatment
PST® is a minimally invasive approach used by trained dentists to treat selected gum-recession cases through a small entry point, without a palatal donor site. An examination is required to decide whether it is appropriate for you.
Find a provider
The Academy website does not currently offer a reliable searchable national directory. Use these steps to find and verify an office near you.
Enter “Pinhole dentist” plus your city, state, province, or region in your preferred search engine.
Ask whether the dentist currently offers PST®, accepts new patients, and how a consultation is scheduled.
Email Pinhole Academy with the dentist’s name and approximate location. The Academy can check its training record.
What to expect
A dentist must evaluate your teeth, tissue, bite, history, and habits before discussing treatment.
The contemporary collagen-membrane protocol uses a small entry point, has no palatal donor site, and typically requires no sutures.
Recession classification, tissue quality, oral hygiene, smoking, tooth position, and healing can affect candidacy and outcome.
