Loose Tooth (Tooth Mobility)

Clinically called Tooth Mobility. It is the movement of a tooth within its socket greater than the normal physiological limit (0.25mm). It is classified from Grade I (slight) to Grade III (severe/vertical movement).

Why It Matters

In adults, a loose tooth is a red flag. It usually signals advanced Periodontitis (bone loss), trauma (from grinding or a hit), or an abscess. Without treatment, the tooth will fall out.

Clinical Details

• Diagnosis: Tested by applying pressure with two instrument handles.
