Make a mouth with playdough and added tic tac mints to the edges to make the teeth. I let it out for a day to harden the playdough a bit. I used dry erase to make dirt prints on the teeth and provided the kids with a tooth brush. There was a reaction from the mints with the Playdough that created a little bit of liquid which was perfect so the kids could easily brush the “teeth.” This is a great way for the kids to practice brushing teeth in a way that they can see it.
