HANDLE OF TOOTHBRUSH HOLDS DENTAL MIRROR (Nov, 1936)
HANDLE OF TOOTHBRUSH HOLDS DENTAL MIRROR
Inspection of the teeth for tartar formation or possible decay is made easy by a new type of toothbrush which contains a dental mirror in its handle. By holding the highly polished reflector inside the mouth while facing a larger wall or cabinet mirror, the user can conveniently and quickly examine both front and back surfaces of the teeth and gums. When not in use, the mirror slides into the handle, where it does not interfere with the ordinary function of the brush.
