Periodontal Disease
Periodontal disease, or gum disease, is inflamation affecting tissue around your teeth. Periodontitis is the leading cause of tooth loss. Bacteria produces toxins that damage the teeth's connective tissue and bone.
Gingivitis, a bacterial infection of the tissues in the mouth, is a potential precursor of gum disease.
What causes it? Improper dental hygiene, organic changes, medical conditions, inhibition of saliva flow, poor functions such as jaw clenching or grinding teeth.
