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.
