Wherever the tissues gaxe way most in the straining there will the teeth strike together first when denture is finished. In sucli cases it may take a whole lot of after-grinding to even passably occlude the teeth in the mouth, and indeed the difference may be so much, here and there, they can't be ground enough to occlude them. Now, doctors, after a little side-lecture on prosthetic quackery we'll return to our case right here where we left it. We 'II shotc yon a way out of all such trouhlc. SIDE REMARKS—PROSTHETIC QUACKERY. And, my dear doctors, I will here beg par- don for a little side lecture, to insist that by far the most dentists set up their teeth too reg- ular to look natural or artistic. The distaste- ful custom is to use white teeth and set them up for the mouth to imitate ])uttons on a paste- board, or tombstones in a national cemetery.
