What should I do if my child or I breaks a tooth or suffer and injury where on or more teeth are knocked out?

What if a filling suddenly comes out? How long can I wait before I seek help?

What should I use to lessen pain until I can get to the dental office?

I've been told I have a cavity, but it does not hurt at all. Why should I get it filled? Why not wait until it hurts?

My tooth hurts all the time. I think I may have a fever.
