What does a "3" indicate on the tooth mobility scale?

A "3" on the tooth mobility scale indicates severe mobility of the tooth. This scale is used by dental professionals to assess how much a tooth can move when pressure is applied. Mobility is typically categorized as minor, moderate, severe, and extreme, with each category signifying a different level of concern regarding the stability of the tooth within its socket.

Severe mobility often suggests significant periodontal issues, possibly leading to tooth loss if not addressed. This level of mobility indicates that the tooth can move more than 1 mm in any direction, or in some cases, may even be depressible within the socket. It is crucial for dental practitioners to recognize this level of mobility as it may require immediate intervention, such as splinting or extraction, to prevent further complications.

Understanding the implications of severe mobility helps in planning appropriate treatment strategies to safeguard the patient's oral health.
