What home remedies to help with a tooth ache actually work?

Call a dentist: The best. Treatment is to call a dentist. And have your painful toot h treated. Tooth decay is cause by bacteria and this ned's to be removed from the tooth and a filling placed. There are no home remedies for this.

Temporary: Whatever you do it will only be temporary. The longer you delay, the harder & more expensive it will be to fix your problem. No home remedy will do anything except temporarily mask symptoms as the problem gets worse. Call your dentist now for an appointment. Until you get there, otc nsaids such as advil (ibuprofen) will help (not cure). But don't delay. Call your dentist now!
