I had a new crown put in about 3 years ago. About a month later it started giving me problems with pain and swelling so I made an appointment for the dentist and he said I would need a root canal.

I started taking a good grade of Oil of oregano by applying it right on the tooth and taking a few drops daily. When my appointment day came my tooth no longer hurt and there was no swelling and the dentist did not see the need to do a root canal.

Like I said that was 3 years ago and my tooth never bothered me again. Just make sure you use oil of oregano with a high carvacrol amount and is Mediterranean grown. There are many internet sites selling a good grade of oil of oregano, so research it and get a good price.
