Among the causes for periodontal (gum) disease are genetic susceptibility, smoking, and other illnesses like diabetes. Periodontal maintenance involves removing plaque and tartar from above and below the gum line. Most gum diseases are preventable with proper oral hygiene. However, what can start out as gingivitis (inflamed or bleeding gums) can quickly turn into periodontitis. In such cases, gums pull away from the tooth to create “pockets,” thereby exposing a dental root to infection. It can also lead to bad breath, loose teeth, painful chewing and other complications.
