Dental mirrors have a number of functions that include not only indirect vision but reflecting light onto tooth surfaces and retracting soft tissues to protect them from sharp burs.

Probes are used for the exploration of tooth surfaces or, more usually, for the exploration of a prepared cavity. This will provide the operator with knowledge of the surface texture and hardness of the dentine surface within a cavity. It should be noted, however, that the use of sharp probes in fissures can break down the surface and accelerate the progress of a carious lesion. The Briault probe is a double ended instrument that is very useful to exploring for cavitation between teeth and under restoration margins. It should be used lightly to avoid iatrogenic damage.

Periodontal probes are used to measure attachment loss, furcation involvement, and bleeding on probing. The WHO probe has coloured bands that correspond to the Basic Periodontal Examination grading system, and this probe has a small ball end to avoid trauma. The Williams probe has markings at 1 mm intervals and is used to make pocket depth measurements around each tooth when completing a periodontal charting.
