Answer
(a) Concave mirror is used by a dentist because if a parallel beam of light is incident on a concave mirror, it converges the beam to the focus. This enables the dentist to concentrate light on small area to be examined like teeth.
(b) A convex mirror is used as a street light reflector because it diverges the light rays incident on it.
