I think it's about someone who lets people(or maybe even the system) push him around because he's too weak to fight back. I think all the dental references are sort of a play on the phrase "bite the hand that feeds" like the hand is right out there waiting for him to bite but he's to wimpy to do it. The other meaning I thought made sense was life's short so don't by standing around doing nothing because you'll regret it.
