Final answer:
Gingivitis is the most common form of periodontal disease and is characterized by the inflammation and bleeding of gums. If untreated, it can progress to periodontitis, which may result in tooth loss. Proper oral hygiene is critical for treatment and prevention.
Step-by-step explanation:
The most common form of periodontal disease is gingivitis. This condition involves the inflammation of gums that can lead to irritation and occasional bleeding. If not properly treated, gingivitis can progress to a more serious condition known as periodontitis, where gums recede and expose parts of the tooth below the crown, potentially resulting in tooth loss and further complications.Good oral hygiene, including professional dental cleaning, is usually effective for treating gingivitis. However, in the case of periodontitis, more rigorous treatment including antibiotics may be necessary. Periodontal disease is typically caused by the overgrowth of oral bacteria due to insufficient dental hygiene.
