Go tp the hospital ASAP. If you have any infection in your mouth it can spread to your blood stream quickly. Pain Usally means infection. You'll need antibiotics quickly. My husband broke a tooth on a friday and decided to wait till monday to save money. Sunday night he ended up in the hospital with celulitis in his face. Admitted for 4 days on I V antibiotics. Not worth the risk.
Clove or clove oil...mouth wash with alcohol.. Vic's vapor rub on the outside... ice pack.. these all work
