Photo of the day, March 12

From our Clark J. Hollister, DDS, Collection. He was an early dental hygiene advocate who established & directed the dental division of the PA Dept. of Health, 1920-1933.

Just think about this many kids being cavity-free in 1925, in pre-fluoride days. How'd they do it?

100 percent perfect condition of teeth. Sixth grade. 03/12/1925. Photos of Hollister and his office, 1908 - 1940's; Hollister Collection; OHA 193.
