THICK vs. THIN GUM (Gingival Biotype, Gingival Phenotype).

These terms refer to the thickness of the gum. It does not refer to a healthy vs. non-healthy gum, but it only describes what type of gingiva (gum) Mother Nature has given us.
Having said that it is important to realize how the thickness of gums can impact our oral health, teeth or dental implants.
A simple way to define it, THIN gum is bad and THICK is good. Simply because Thin tissue can be stretched causing recession around teeth and dental implants, while a THICK gum is firm, bound to the underlying bone and protects teeth and dental implants.

Most people with Thin gum, are at high risk to get gum recession. 78% of sites with untreated gum recessions, even with good oral hygiene will get worse through time. Gum recession is not related to how good your oral hygiene is. The thinner the gum the easier it gets traumatized while brushing or eating and then it recedes. In certain cases, the damage is permanent and repair to ideal is impossible. (Photo above compares the gums of a 52 year old on the R side vs. the gums of a 24 year old on the L side.)

Even during smiling, eating and talking the facial muscles will stretch the gum causing recession, something that you might not even be aware of. Roots are not covered with enamel and hence they are softer. When the roots are exposed, they wear much faster during normal daily brushing. This makes you get cavities easier on exposed softer root surfaces, when compared to hard enamel covering the crown.

When you’re getting things like crowns, veneers, or fillings, or even surgeries like placing a dental implant or periodontal surgery, how thick your gums are matters a lot for healing and the results over time.
Thicker gums are like a shield—they resist irritation better and stay healthier in the long run.

What can be done if one has THIN gums.

Gums can be grafted to change its appearance. Different sources for Gum Grafts are from patients own mouth (usually palate) or from a tissue bank (cadaver). For those who do not like the idea of taking tissue from their palate, Cadaver soft tissue is a better option since it eliminates the donor site on the palate.

Gum Graft can be used to cover an exposed part of the root, instead of using white filling or bondings (Bondings needs to be replaced frequently, depending how well it is done in the first place)

The case presented below is an example of a single site root coverage.

Gum Grafts can also be done for multiple teeth in a single visit to build up thick tissue and cover exposed roots.
By thickening the gums the risk of recession is minimized, saving you several fillings, teeth sensitivity, cavities, etc. in the future.

There are times gum recession happens despite the fact that there is a relatively thick gum. These are instances that other anatomical factors adversely influence the health of the gum. Below is an example.

Severe localized gingival recession.

This single site recession can reasonably be improved with Gum Graft. The sooner you treat the site the more predictable the root coverage will be.

Gum Grafts before orthodontic treatment in people with thin gums is a common practice and will help your teeth stay healthy and beautiful. Gum Grafts can also be used to PREVENT further recession. It is not uncommon to perform gum (gingival) graft before orthodontic treatment, because teeth movement accelerate recession.

If you’re planning on getting braces or Invisalign, it’s crucial to have your gums checked first. This ensures you won’t make the condition of your gums worse and helps keep your oral health in check.
