THE BEST THING TO TAKE is a trip to the dentist to have the "severely painful" wisdom tooth removed. I would think a localized shot of Novacaine would be much safer for your unborn baby, as opposed to taking ANY kind of pain killer orally. Plus, if your wisdom tooth is VERY painful, it's probably IMPACTED, so you could eat pain killers every day and it won't CURE it. It will only treat your symptoms (tooth pain), and will not get to the ROOT (get it?? root haha) of the problem. So please go see Dr. Happytooth as soon as possible. GOOD LUCK ! <<<ADR>>>
