My sister is having severe super severe pain at her molar teeth. Its night and we can not contact any doctor till tomorrow. PS Tell a momentary way of controlling it. She is crying in pain and is reminding me of the days when doctors used to operate on patients without any anesthetics. Any help will be appreciated.

What pain killers, or dental pain killers, are available at this time? Is the emergency room an option?

Look up in phone book or google for emergency 24 hr dentists in your area.
It will be a hefty fee probably but it is possibly another option.
