Gum recession causes the body to lose its natural ability to protect the mouth from bacterial penetration and trauma. If serious recession occurs, gum grafting techniques can be used to reconstruct the gingiva.
Some cases of recession can be treated with simple modifications to your at-home care routine. However, if the recession reaches the mucosa, the body no longer has a way to defend against the threat of bacterial penetration.
In addition to the bacterial risk and exposure of the gum and tooth, gum recession can cause discomfort and sensitivity to hot and cold foods. If the recession grows worse, it can expose the soft surface of the root and lead to root caries and root gouging.
