Which toothpaste whitens the best?



I recently asked a question regarding an experiment with differnt toothpaste - which ones whitens the best.

We have a science project due this week and we heard that using eggs was a good source for staining and then to brush with the various brands of toothpaste. My question was whether it mattered using white or brown eggs and should they be hard boiled or just use the cracked shell. I am hoping you can get back to us ASAP..Thank you for all your help.


Using brown eggs is just fine.  You do not have to boil them.
