I was dealing with some dental pain from a dry socket and she suggested the essential oil tea tree could help ease the pain -- and it did. You have to be careful about tea tree oil though, only in that there's a type you can use as I did in my mouth and the type you use externally. This is an amazing hidden gem the medical community really doesn't want you to know about.
