Imako® Products' Tooth Tinted Thermoplastic comes in a small package which contains two chunks of thermoplastic which can be modeled to fill an area where a tooth is missing, chipped tooth, or gaps between teeth. It's popular because the competing products are too white. Thermoplastic can be melted with simmering hot water to be like taffy so you can shape it. When it cools it hardens. This can be done over and over. You can bond two pieces together by having a melted surface touch another melted surface. You can polish the surface by briefly steaming or dipping the surface to melt just a bit, then smooth by rubbing with a wet finger.
We recommend you use enough to spread out a thin layer to fit into crevices on the back of neighboring teeth to get a reliable fit.
Proceed with caution with sensitive chipped teeth.
