Gum recession is the progressive loss of gum tissue which can eventually cause tooth root exposure. Regular dental checkups will help prevent gum recession and assess risk factors. Symptoms of gum recession include tooth sensitivity, visible roots, longer looking teeth, halitosis (bad breath), inflammation, and bleeding. It can be caused by overly aggressive brushing, poor oral hygiene, chewing tobacco, and periodontal disease. Once the cause of gum recession has been determined, surgical and non-surgical procedures can be performed to halt its progression and correct it.
