Pain concerns: You didn't ask a question but you need to see a dentist to get your teeth treated. Your toothache will not be cored without treatment. What are you taking for pain? Excessive pain medications may be causing the vomiting but many other things can also. See a physician about this. Get the care that you need. Don't put this off any longer.

Wrong approach: Pain killers will NOT cure your dental issues. You are just prolonging the inevitable... a visit to the dentist. Why wait? The end result will be the same; minimize your anguish and call for an appointment.
