For patients considering gum-recession treatment

Understand the option. Find the right doctor.

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.

Start with three questions

  1. What is causing my recession?
  2. Am I a candidate for PST®?
  3. What result is realistic for my case?

Find a provider

A practical search path—without a misleading directory.

The Academy website does not currently offer a reliable searchable national directory. Use these steps to find and verify an office near you.

  1. 01

    Search your city or region

    Enter “Pinhole dentist” plus your city, state, province, or region in your preferred search engine.

  2. 02

    Contact the office directly

    Ask whether the dentist currently offers PST®, accepts new patients, and how a consultation is scheduled.

  3. 03

    Verify certification if needed

    Email Pinhole Academy with the dentist’s name and approximate location. The Academy can check its training record.

What to expect

Your consultation determines the treatment—not a website.

  1. 01
    Why gums recede

    A dentist must evaluate your teeth, tissue, bite, history, and habits before discussing treatment.

  2. 02
    How PST® is described

    The contemporary collagen-membrane protocol uses a small entry point, has no palatal donor site, and typically requires no sutures.

  3. 03
    Why results differ

    Recession classification, tissue quality, oral hygiene, smoking, tooth position, and healing can affect candidacy and outcome.
