Fountain Brush Sprays Teeth (Oct, 1933)

She really does seem to enjoy doing that.

Fountain Brush Sprays Teeth
A FOUNTAIN toothbrush, which forces a liquid carbonic spray through the bristles, thoroughly cleans the teeth and acts as an atomizer at the same time.

The flow of the liquid is controlled by pressing a lever on the container holding enough cleaning fluid for a month. The device is a Norwegian invention.
