Plz mark me as the Branliest !!!
Explanation:
Concave mirrors are used by dentists because they are converging mirrors and reflect light to the focal point. Also, at a short range (object distances less than the focal length of the mirror) they produce enlarged, erect and virtual images. It is useful to have a magnified image of a tooth when repairing cavities, cracks, or other abnormalities.❤️
