Tooth pain can be unbearable. When anyone in my family has tooth pain we apply tea tree oil to the surrounding gums front and back for as long as it takes to go away. If you are lucky it will only take 1 day. I have had to do it for a week straight in the past. We do this before making a dentist appt. to see if it is more of a fungal problem than a tooth decay. If the pain never goes away then we make the dental appt.
Tea tree oil is an antifungal and is fairly cheap, around five dollars a bottle.
Wishing you much luck and no more pain...heyjude
