Periodontal disease is irreversible and involves bone loss around the tooth.
a. true
b. false

The answer to the question: Periodontal disease is irreversible and involves bone loss around the tooth, would be, A: true.

Explanation:

Periodontitis and gingivitis are two conditions of the mouth that are pretty severe. To reach these levels, a person´s exposure to plaque, tartar, and bacteria in the mouth must have been pretty long. Gingivitis is an inflammation of the gums of the mouth, and if taken proper care of, it can be reversed. In this case, professional care is needed, but the problem can be reversed. However, when we move on to periodotitis, we have a further problem because in this case, the damage is not just to soft tissue, but also to the bone itself, and there is a destruction of the periodontal ligaments as well as destruction and absorption of parts of the alveolar bone. Periodontitis is almost totally irreversible.
