I have 4 residual tooth roots that have been bothering me for years, i have the extraction for next month, i'm in severe pain and weak health, what can i do to feel better and protect my health until i'll get my extraction?

You should consult with the dentist who is treating you to see if you can get a sooner appointment. If not, antibiotics may be in order.

Soft high-protein diet. Ask y9our Dentist if antibiotics are in order. Make y9our mouth as healthy as possible by brushing 2x/day for 2 full minutes, and most of all by flossing daily. Stay away from alcohol, and don't smoke anything. And see if your Dentist can get him in any sooner.
