Clove or clove oil...mouth wash with alcohol.. Vic's vapor rub on the outside... ice pack.. these all work
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.
