What is a good title for my daughter's science fair project?

Question

We are soaking ceramic tile (in place of teeth) in cola, tea, and grape juice for 2 days. Tomorrow we will be using 3 different cleansing agents to see which will remove the stains. We need a catchy title to bring it all together.

Answer 1

"Towards Brighter Smiles: an experiment to improve stain removal on teeth"

or

"Pearly Whites: which product removes the worst stains from teeth?"

hth

Answer 2

- Why brushing your teeth for three minutes is a great idea.

- Why teeth HATE cola

- Out d**n'd spot! (Did Lady MacBeth brush her teeth?)
