BEST GUM DENTIST IN CHENNAI! Do you use a toothbrush with hard bristles? Do you brush your teeth too vigorously? Do you neglect to regularly floss your teeth? Do you have parents with receding gums? Then you may suffer from receding gums, exposing the softer part of your teeth below the gum line. Periodontal disease is the most common cause of gum recession. That’s when plaque builds up on teeth producing gingivitis, leading to periodontitis. Gums recede in reaction to the acids produced by the bacteria in plaque. Neglected long enough the receding gum line gradually exposes tooth roots. Some people may inherit thinner gum tissue. Or there may be other factors that make them more prone to receding gums. Besides being able to see the exposed tooth root, there is often increased sensitivity to hot or cold. Gum surgery may be necessary to protect your teeth and avoid bone loss.
