Which medicine is the best way to help the pain until I can finally get the teeth removed?

Dental problems. If the teeth are infected (dental abscess), you may want to get an antibiotic from your doc/dentist to prevent complications. For pain, there are topical gels like anbesol/orajel or lozenges with Benzocaine or for pain & inflammation, use an NSAID like aleve/motrin/etc (if they won't interfere with other meds you may be taking or cause stomach problems.
Pemf. Use pemf devices to get rid of the pain from tooth. Will help open up the lymphatics immediately so make sure you are on antibiotics to prevent feeling sick.
