Final answer:
Gingivitis can progress to periodontitis if left untreated. Periodontitis is a more severe condition characterized by gum recession and tooth damage. Treatment involves cleaning, dental hygiene, and antibiotics in severe cases.
Step-by-step explanation:
Gingivitis is the inflammation of the gums that can lead to irritation and bleeding. If not treated, gingivitis can progress to periodontitis, which is a more severe condition. In periodontitis, the gums recede and expose parts of the tooth below the crown, allowing bacteria to grow and cause further damage. Treatment for periodontitis may involve cleaning, dental hygiene, and in severe cases, antibiotics.
