What does the term 'supernumerary tooth' refer to?

1. A missing tooth.

2. A tooth that develops in excess of the normal count.

3. A tooth that is smaller than usual.

4. A tooth that grows with a deformity.

The correct answer is: A tooth that develops in excess of the normal count.

The term 'supernumerary tooth' specifically refers to a tooth that develops in excess of the normal count of teeth. In humans, the typical number of permanent teeth is 32, and any additional teeth beyond this number would be classified as supernumerary. These additional teeth can occur in various forms, such as an extra incisor or molar, and can develop in different areas of the dental arch. This condition can lead to a variety of dental issues, including crowding, misalignment, and difficulties with oral hygiene. Understanding this term is essential for dental professionals as it aids in diagnosis and treatment planning, particularly if a patient presents with dental anomalies. Other options describe different conditions, such as missing teeth, or abnormalities like size or deformities, but do not accurately convey the meaning of supernumerary teeth.
