We made up a fun game to play to help them be willing to let me brush their teeth. We like to call it “Dinosaur Dentist” or some other ‘type’ of dentist.
I lay them in my lap and and have them open up. I start brushing but use alot of expressive dialogue such as: "Oh, what big teeth you have!", "Your teeth are so sharp!", and "They are getting cleaner!". The goal is to brush their teeth for a full 2 minutes since that's the dentist recommendation. By making teeth brushing time into a game, we are able to effectively brush their teeth and have a little fun!
