Anyone have any home remedies to help an abscess tooth or relieve the pain?

The pain is from the build up of infection under the tooth because it cant release. If you allow it to go on, even if you can find something to stop the pain, that infection can transfer to other areas of your body. Get to a dentist NOW and have this taken care of.

I agree! 25 years ago, I got sicker and sicker for 10 months from a lung infection from a hidden crack under a crown.
3-4 days after the tooth under the crown was extracted, I was better. Months of more and more expensive antibiotics had done nothing.
