HOSA Dental Terminology Practice

What does it mean if a tooth is described as hypermobile?

1. It is loose in its socket

2. It has excess enamel

3. It is rooted deep within the socket

4. It shows no movement

The correct answer is: It is loose in its socket

When a tooth is described as hypermobile, it indicates that the tooth is loose in its socket. Hypermobility refers to an abnormal degree of movement, which in this context means that the tooth can move more than what is considered normal due to factors like periodontal disease or trauma. This condition can be concerning as it may lead to further dental issues or indicate underlying problems with the supporting structures of the tooth, such as the gums and bone. The other options do not correctly define hypermobility. For instance, having excess enamel refers to a condition known as "enamel hyperplasia," which is unrelated to tooth mobility. A tooth being rooted deep within its socket suggests stability rather than movement, while showing no movement indicates that the tooth is firmly anchored, contrary to what hypermobility implies.
