One of the most common concerns our patients ask us about is “receding gums.” which is technically known as “gingival recession.” Receding gums is the process by which the gum tissue surrounding a tooth recede – or “grow down” over time. While the gum recede, the tooth may start to appear to look longer or darker. The tooth looks longer to the eye because there is less gingival tissue covering it. Similarly, the tooth hasn’t changed color at all, but with the recession, you are now seeing the naturally darker part of the root’s surface.

 

When there is only minor recession, some healthy gingiva often remains and protects the tooth, so that no treatment other than modifying home care practices is necessary. However, when recession reaches the mucosa, the first line of defense against bacterial penetration is lost.

 

In addition, gum recession often results in root sensitivity to hot and cold foods as well as an unsightly appearance of the gum and tooth. When significant, gym recession can predispose to worsening recession and expose the root surface, which is softer than enamel, leading to root caries and root gouging.
