Lab

The objective of this lab was to determine which toothpaste works best for removing stains. We thought that the toothpaste with the highest sodium-fluoride concentration would work best for stains. This lab was done by brushing an egg with a toothbrush that had been wetted and either had pepsodent, crest, or ultrabrite toothpaste on it. We then compared the eggs before and after brushing them in order to learn which toothpaste is the most efficient.
