What type of toothpaste will clean stained teeth the best?
Posted on July 9, 2010
That is my science fair project. I will be using tartar control toothpaste, fluoride toothpaste and non-fluoride toothpaste.
-How do I record the shades of the stained and clean teeth?Is there some kind of machine I can use?
-Where could I get actual teeth?Dentist?
-What would be a good hypothesis?Has to be an "If......then......"hypothesis
-How I properly stain them.

You can buy a dental shade guide on eBay
Yes, you can collect teeth from your dentist’s office or local dental school.
If brushing is done within 15 minutes of eating food containg color, then the degree of staining can be reduced by say 45%
