I think this is beyond self help. You need a dentist.

(last November I was eating a bagel and heard a crack. I lost the same tooth you're talking about. Granted, it was a baby tooth that never fell out, but I'm still missing the tooth now and it's been a real self esteem killer. Like I have $3000 to get a bridge put in. Pfffft. Yeah right).

Get yourself to the dentist while there's still time for some $5 antibiotics to take care of it. Most dentists let you pay over a period of 90 days too.
