Why dentist use concave mirror?

Dentists use concave mirrors to view teeth and other areas of the mouth. This is because a concave mirror forms a virtual, erect and enlarged image when the object is brought into focus. A dentist uses a convex mirror because it forms an enlarged or enlarged image of an object when held within the focus of a concave mirror. Dentists use a concave mirror to see an enlarged image of the teeth for examination.

If an object is placed close to a concave mirror, it forms an erect, enlarged image of the object. Therefore, the dentist holds the mirror in such a way that the tooth is within its focus. The convex mirror will result in an erect virtual image but smaller than the real size. Decreasing the image of the teeth will not help the dentist identify the dental problem.
