When testing tooth mobility in what direction is the tooth tapped?

Buccal-lingual
Buccal-anterior
Buccal-posterior
Buccal-mucosa

Explanation

Answer: A - When testing tooth mobility, the tooth is tapped in the buccal-lingual direction with the aid of two instruments. The tooth can move physiologically and pathologically. Physiological movement allows slight movement without injury to the tooth or supporting structures. Pathological movement results from connective tissue attachment loss.
