Toothache pain...Any cures or home remedies?

Not a great answer. I'll be honest and say that any relief you get will be temporary. You need to get to the dentists asap. Anti-inflammatory such as Ibuprofen will help temporarily. I've even seen people whole will take a clove and stick it in the cavity (eugenol is a sedative to the tooth). Doesn't work to well. Do yourself a favor and see the dentist before the weekend.
No. You must visit your dentist and evaluate the source of the pain, gums, root canal, etc.
OTC pain meds... ... For only a short while. There is no way for you to treat yourself to restore a rotten tooth. The sooner you call a dentist for an appointment the sooner you will feel better.
