The tooth shall set you free
My dentist said it was infected, but at the time I couldn't afford a root canal (I have one scheduled for July 2), so I've been treating it with copious amounts of Advil. Now my ear hurts and I'm always tired. I expect that's from spreading infection? Anyway, I used a credit card to get the antibiotics, so maybe I'll feel better.
The point? I'm thinking it's no fun for folks who have no job and no insurance in our society. Life is hard enough for them without having to endure daily pain (and there's no pain like tooth pain). Canada has many failings, but they provide some level of care for everyone in their borders. No tooth left behind.
