Husbands tooth filling came out, tooth is now extremely loose! Should he pull it out? What can I do to ease pain for him before we can get to dentist!?

Maybe. Pain meds can help decrease the pain. I have had a few patients pull their own teeth with no problems but usually they are very loose...
See a dentist. I would not pull the tooth unless it just falls out. You can use anbesol or oragel to numb the area until you see the dentist.
Dentist. See your dentist asap. Try 1 Ibuprofen 200mg and 1 Acetaminophen 500mg mixed together every 4-6 hrs as long as no allergies or past adverse rxns. With either.
