Final answer:
Gingivitis is a condition characterized by inflammation and erosion of the gums. If left untreated, it can progress to periodontitis, which can lead to tooth loss and jaw bone erosion.
Step-by-step explanation:
Gingivitis is a condition characterized by inflammation and erosion of the gums, which can lead to bleeding and halitosis. If left untreated, gingivitis can progress to periodontitis, a more serious condition where the gums recede, exposing parts of the tooth normally covered. Periodontitis can lead to tooth loss and erosion of the jaw bones.
To treat gingivitis, good dental hygiene and professional dental cleaning are recommended. For periodontitis, antibiotics and appropriate dental hygiene may be sufficient, but severe cases may require a combination of antibiotics.
