Toothpaste is enriched with fluoride to help prevent tooth decay. Fluoride ions are anions, meaning they have a negative charge. (Take a look at where fluoride falls on the Periodic Table -- fluoride ions want to gain an electron to be more stable, thus they tend to form ions with a -1 charge.)
Substances with negative charges are basic, while those with positive charges are acidic.
