Gum Recession (Gingival Recession) occurs when the gum tissue around the bottom or sides of your teeth begins to recede (draw away and disappear). It can be caused by periodontal (gum) disease, brushing your teeth too hard, brushing with a hard-bristled toothbrush, trauma from sports or other injuries, the stress of braces on crowded teeth, genetics, tobacco use, or dentures that fit incorrectly.
Gum recession exposes the roots of teeth, which can lead to sensitivity and put teeth at a higher risk of damage or disease. Teeth with receding gums may eventually become loose and fall out. Once the gum tissue has receded, it does not grow back by itself. To correct the condition, you need to see a Periodontist to get a Gum Graft.
