Which instrument is typically used to check for mobility of teeth?

The periodontal probe is specifically designed for assessing the health of the gums and the attachment levels of teeth, which includes checking for mobility. It is a calibrated instrument that allows the dental professional to measure pocket depths around the teeth and evaluate the condition of the periodontium (the supporting structures of the teeth). When assessing for tooth mobility, the practitioner gently applies force with the periodontal probe to determine if there is any movement in the tooth, indicating underlying periodontal issues.

While other instruments are useful in dental practice, they serve different purposes. A dental mirror is primarily used for visibility in the mouth, a probe may refer to a general or exploratory probe used for various purposes, and a scaler is mainly utilized for removing calculus from the teeth. None of these alternatives provide the same specific functionality regarding tooth mobility assessment as the periodontal probe does.
