Will it kill me if I use it?

Does toothpaste go bad? Yeah, I know there is a date on them, but will it kill you if you use it after that date or is that a "best by" date?

Why am I asking? I seem to have overstockpiled my toothpaste. When we lived in Florida, there were CVS stores all over and I got carried away with their "Extra Care" program. I wound up with so much totally free toothpaste--mostly Colgate--that I haven't bought toothpaste in almost two years and I still have a huge stack.

I've moved my stockpile from Florida to WV and now it sits here staring at me. I'd take a picture, but my camera is on the fritz. So my question is, how long will this stuff last? I've stopped buying it but I have some really good coupons I'd like to use.

Yes, I have a coupon addiction.
