Two of the three hats Larry hangs on a perch, when the Stooges first enter their dental office, disappear mysteriously, when the sheriff barges in.
Larry Fine can be seen cracking up several times when Shemp is working on the first patient.
The clothes Larry Fine's stunt double wears does not match the kind when he and the Stooges are tossed out of the dish company and the restaurant.
Shemp Howard trips over and almost falls when he says the line "Let's see what's next."
When Shemp is rubbing sandpaper on the sheriff's chest, Dick Curtis can be seen trying not to laugh, even though his character was supposed to be sleeping.
Because of the deleted footage featuring the Stooges as dentists out west in their previous short Merry Mavericks, there is a character goof that Shemp was the only one that graduated from dental school with a diploma, even though in the new footage, they all graduated.
Though Shemp tells Moe that his left arm is shaking nervously, his right arm is seen shaking instead.
