Gum recession can make teeth feel sensitive, look longer, and become more vulnerable near the roots. At Le Smile Aesthetic & Comprehensive Dentistry, we offer Chao Pinhole® Surgical Technique, also known as PST, as a minimally invasive option for treating gum recession and helping protect exposed tooth roots.
 

What Gum Recession Does To Your Teeth

When gum tissue pulls away from the teeth, the tooth roots can become exposed. Unlike enamel, root surfaces are not designed to handle daily brushing, temperature changes, and acids in the same way. This can lead to sensitivity, discomfort, and a higher risk of root damage over time.

Recession may happen gradually, so many patients do not notice it right away. By the time sensitivity becomes obvious, the gums may already need attention.
 

Why Exposed Roots Cause Sensitivity

Tooth roots contain tiny channels that connect to the inner nerve area of the tooth. When the gumline recedes, hot, cold, sweet, or acidic foods and drinks can trigger discomfort. Even brushing or breathing in cold air may cause a sharp sensation.

PST helps address this by repositioning gum tissue over exposed areas, which can reduce direct contact with the sensitive root surface.
 

How PST Helps Protect The Root Surface

The Chao Pinhole® Surgical Technique uses a small entry point to gently loosen and reposition gum tissue over areas affected by recession. Because there are no traditional incisions or sutures, many patients appreciate that PST is designed to be less invasive than conventional gum grafting.

By improving gum coverage, PST may help:

• Reduce exposed root surfaces
• Lower tooth sensitivity linked to recession
• Improve the appearance of an uneven gumline
• Support long-term root protection
• Help prevent further irritation from brushing or chewing

Why Treating Gum Recession Early Matters

Gum recession does not usually reverse on its own. If exposed roots are left untreated, the area may become more prone to sensitivity, abrasion, decay, and changes in tooth stability. Early evaluation allows us to determine whether PST is a good option before the recession becomes more advanced.

We also look at what may be contributing to the problem, such as brushing pressure, bite issues, gum health, or teeth grinding. Treating the cause is an important part of protecting your smile after PST.
 

What Makes PST Different From Traditional Gum Grafting

Traditional gum grafting often involves taking tissue from another area of the mouth and placing it over the recession site. PST uses a different approach by adjusting existing gum tissue through a small pinhole opening.

This technique may offer a more comfortable experience for the right candidates, with less surgical involvement and no need for donor tissue from the palate. Our goal is to help restore gum coverage while keeping treatment as conservative as possible.
 

Is PST Right For You?

PST may be recommended if you have gum recession, exposed roots, tooth sensitivity, or cosmetic concerns about a receding gumline. During your visit, we evaluate your gums, teeth, bite, and oral health to decide whether this treatment fits your needs.
