Swish grain alcohol (Everclear) mixed 50/50 with water (same as vodka).
Then swish Colloidal Silver or oregano oil or coconut oil to leave bacteria fighting residue in mouth. In fact swish these for as long as possible so they permeates any exposed teeth tubules / dentin and gums.
Reduce your Sugar intake as much as possible to keep blood Sugar down to limit bacterial growth.
Stop taking pain killers if at all possible - they make it harder for the body to fight the infection. Don't take anti-inflamatiories either - they prevent the body from sending blood to the infection/injury.
