1 Dozen Doll Teeth One dozen doll teeth have six sizes in the package. There are two of each size. These are made of plastic or acrylic. You can trim them with scissors if you have to, in order to get them to fit your doll. We used them for a vintage Chatty Cathy doll one time and although not as good as her original teeth, they really do look good once they're installed. The little pointed tab is inserted in a slot in the doll's mouth. Use a little dab of glue on the tab to secure the teeth. Very easy!
