The rip and grind food into small chunks.

It would have helped to answer this question, if there were some options to choose from. I am answering the question based on what i understood. I hope that it helps you. The teeth rip and grind food into small chunks. This is also the main function of the teeth and it does help in the digestion of the food we take.

I'm not sure what your asking buddy.. but i know that you can weld two peices of steel by pure force and pressure.
