Receding gums can grow back, but only if your gum recession is in its initial stages, specifically in the gingivitis stage.
More Info: Otherwise, as when it reaches periodontitis or advanced periodontitis, the gum recession is irreversible and the gums will not grow back. (See What Are the Stages of Periodontal Disease) There are treatments however, that are available to treat receding gums that are in the advanced stage, but they do not involve the natural growth of the gums.
What is Gum Recession?
Gum recession or receding gums is a common condition that goes mostly undetected, wherein the marginal tissue surrounding the teeth wear away towards the roots of the teeth, thereby exposing more teeth than is normally found in healthy gums. Receding gums is one of the first signs of gum disease.
Why Are Receding Gums Potentially Dangerous?
Receding gums can potentially lead to a more dangerous or advanced form of gum disease, because when recession happens, pockets or gaps form along the gum line, making the gum line more prone to build up caused by plaque bacteria. Once these pockets of bacteria are formed along the gum line, this causes the bones and tissues that support the teeth to weaken or to be destroyed, thereby causing the teeth to likewise loosen or fall off.
It is important to note that gum recession is a common problem that afflicts many individuals although they are now aware that they have it. The most common signs or symptoms of gum recession are increased sensitivity of the teeth, irritated and inflamed gums and more exposure of the tooth or teeth, making it look longer.
It is only when gum recession, caused by gum disease, is only in the gingivitis stage that is can be reversed and treated so that there will be a possibility that the gums can grow back to a healthy state. More advanced gum disease, specifically advanced periodontitis, causes the gums to recede further and requires more intense treatment involving soft tissue grafting, which restores the receded gum lines using grafting.
