Please note that this is advice on dental care from the 1940’s. If you find that they differ from what your dentist tells you, then I think you should listen to your dentist!
The best way to ensure beautiful teeth is to take care of them. Brush your teeth morning and nights with a hard toothbrush of good quality. Make sure that you brush every angle of every tooth that you get to and lightly brush the gums too. Rinse the mouth after every meal with tepid water; possibly add a few drops of refreshing mouth water.
