Introduction
You've probably gone to the dentist before and had to wait in
the waiting room with several other people. Well have you ever
wondered why all those people are there? This project helps you
to understand the process that causes a tooth to decay. You will
also learn to protect your teeth and prevent tooth decay. |

Material and instructions:
You collect some information,
do a few experiments and make a display for your presentation.
It will take one to three weeks to complete this project, but
it is worth the time. You will need to write a report about your
findings. For your display you may also make a large model of
a tooth and paint it to show what areas of a tooth are at risk
for a cavity. The experiment requires tooth samples. It is not easy to
find human teeth for your experiments. Some students try using animal
teeth that is available from a local butcher. Some others use chicken
bones or seashells as a substitute for teeth and for faster results. |
Details of
this project
More details of this project is available in the members section of ScienceProject.com
web site. Since research on this subject has a long history, you may
also be able to find good books about it in your local library or find
some information on the internet.

A collection of seashells that students may use as display or
for research is available at MiniScience.com online store. Since
seashells are made of natural calcium carbonate, many students
use it to test the effect of acids on it or use it as a
substitution for bone or tooth for simplified experiments.
