Mouth Mirrors

About mouth mirrors

A mouth mirror is a handle with a thin circular mirrored surface on the working end, which lets the inside of the teeth and the rest of the mouth be seen. It is used to look for bacteria, cavities and calculus in places that are hard to see directly. Three mirror faces are in use — front surface, concave and plane surface — and the front-surface mirror is the one most often used because it gives a clear image.

The only one of these that does not touch what it examines: it is there for indirect vision and light reflection.
