"I got my brother the olive leaf extract and he's taking it. Why should I take it? Is it going to relief pain?"

It might, or it might temporarily make the pain worse. If you have infections in your mouth, it may help cure them, but you may feel worse temporarily due to die off reactions candida or bacteria are being killed.

Do you rinse your moth with warm salt water? Rinsing with warm salt water, and using Listerine advanced helped me. I also like using 'The Doctors" brand platic tooth picks. I use them before I floss.
