Science Buddies: "Ask an Expert"

i need to show an example of teeth worn out by soda. i dont know what to use as "teeth" whats the closest thing to it?

I think the best thing would be to ask google. Searching on google might give you an idea of what teeth are made of. I am sure it will be a readily available material.

Hello,

Another option may be to use actual teeth.

A local butcher might be willing to give you animal jaws very cheap. Which animal has teeth most like a human is something you'd have research.

If that doesn't work, you can probably find a supermarket that sells whole pigs heads, from which the jaws or teeth could be removed.

There are also online suppliers who will sell you jaws or complete skulls from various animals, although it will probably cost quite a bit. You might even be able to find a supplier for human teeth, although medical waste disposal requirements may make that impossible depending on where you live. (Which is a good thing, since handling human parts can be dangerous!)

In any event, if you do try to use real teeth, make sure you handle the material safely and talk to those in charge of the science fair about any restrictions on using animal parts.

Good luck,
Erik
