The mirror used by a dentist to examine the teeth of a person is:(a) convex (b) concave (c) plane (d) any one of the above

(b) concave

Explanation

A concave mirror is used by a dentist to examine the teeth of a person because it helps the dentist to see a magnified image of a tooth which made it easier to check for a defect in the tooth. 

A concave mirror can produce an enlarged or magnified image of an object (here, teeth) when it is held within the focus, $F$ (between pole, $P$ and focus, $F$) of a concave mirror.
