1. Physiological gingival recession
With age, there may be a small amount of gingival recession, such cases are more common in the elderly, but caused by less sensitive teeth.
Periodontitis is due to long-term bad oral hygiene lead to dental calculus, dental plaque in the gingival margin, the accumulation of interdental, sustained release of toxins to stimulate the gums, resulting in swollen gums, bad breath, loose teeth and a series of adverse consequences.
After periodontal treatment such as scaling, periodontal scaling, the treatment eliminates periodontitis inflammation and local irritation, the original swollen gingival inflammation gradually restored due to periodontitis caused by alveolar bone withdrawal and Dependency of dental caries and teeth loss, the gradual shrinking of the gums, exposing the roots.
3 missing dentition
Teeth dislocation, do not underestimate the problems caused by missing teeth! Alveolar bone is also so much, once the teeth crowded, some teeth covered the alveolar bone can be thin a lot; this case, once bite something When or habit is not good, it may cause further absorption of alveolar bone, gum naturally shrink. Sometimes, some people have poor natural anatomy and particularly large bifurcations. The risk of tooth alveolar bone resorption is greater than that of normal teeth.
Brush your teeth violence, the wrong way
Wrong brushing method, improper use of force will stimulate the gums, brushing your teeth are often more prone to gingival recession, because at this time rather than brushing teeth "saw" the alveolar bone and gums; incorrect use of toothpicks will stimulate the local teeth Meat and alveolar bone, the formation of gingival recession.
5. Poor oral prosthesis
If you do bad dentures, such as removable denture fixtures (clasp), stimulating the gums, inflammation will occur, resulting in gingival recession.
