Dear Praveen,
Activated charcoal often helps with tooth pain. If you can get tablets, you can just hold a tablet at the site of pain. It will slowly dissolve.
Black Walnut has been a help to some with cavities. If you can get Black Walnut tincture, you would add a dropperful to an ounce of water and swish it in your mouth for 20 seconds and swallow it, twice a day.
