Increased mobility of teeth and the recession of gums can be caused by various factors; most often it is due to periodontitis. Periodontitis is a chronic inflammation of the gums which also damages the jawbone. If the disease is not diagnosed or treated in its early stages, it results in complications and, ultimately, in tooth loss. The main cause of periodontitis usually is not an unhealthy diet or a severe general disease, but insufficient oral hygiene and incorrect tooth cleaning techniques. A professional opinion is essential for a correct diagnosis and treatment plan.
