There are three basic types of mirrors - the flat, the convex and the concave mirrors. The flat one is the one that we use to look at ourselves, in our homes etc. Imagine a large bowl as a mirror. Now we can assume that the outer curved portion of the bowl acts as a convex mirror and the inner portion of the bowl as a concave mirror. If you stand between the focal point and the pole of the mirror, then the nature of the image formed is virtual, erect and magnified. These kinds of mirrors are a little thicker, and they bend light towards you. When you move towards the centre of the mirror, the object appears enlarged, and when you move further away from the centre, you'll notice a diminished image. A person who is shaving keeps his face closer to the centre of the mirror, that is between the pole and the focal point. Hence, it appears enlarged. This is the reason why concave mirrors are used as shaving and makeup mirrors. read less

This happens because when the object is kept at a distance less than the focal length of the concave mirror the image formed will be virtual, erect and enlarged. The position of the image formed will be behind the mirror, ie we can see it inside the mirror and all other imnages are formed in front of the mirror. read less

Concave mirrors are used by dentists because at a short range (object distances less than the focal length) they produce magnified, upright images. It is useful to have a magnified image of a tooth when you're looking for or repairing cavities, cracks, or other abnormalities. ... Shaving mirrors.

Concave mirrors concentrate on one focus and while shaving it concentrate on a point and the image is enlarge which prevents the face from cutting.

Concave mirrors concentrate on one focus and while shaving it concentrate on a point and the image is enlarge which prevents the face from cutting. For concave mirrors,when the object is nearer (i.e. between focal point and mirror),the image is upright and magnified. For shaving,mirror is generally held near the face. So the face comes between the focal point and the mirror due to which magnified image is formed which helps in making a smooth shave. read less
