<s>[INST] I am 30weeks pregnant and have a tooth abscess with pus draining out, I have a severe headache and regular tylenol is not helping. I have a dentist appointment this thursday, went to my OB yesterday and didnt want to prescribe anything. What should I do? [/INST] Thanks for your query, I have gone through your query. The abscess and pain in the head region is because of the tooth infection. You have to take a course of antibiotics and analgesics. Without prescription do not take any medicines. After consulting an oral physician or your gynecologist you can take the medicines like amoxicillin 500 mg TID and paracetamol 500 mg TID (if you are not allergic).once you deliver you can take a radiograph to see the condition of the tooth and treat the tooth with RCT or extraction. I hope my answer will help you, take care. </s>
