It should start to feel better in the next couple of days as it heals but if the pain get really bad, head back to the dentist you could have dry socket. And bny807 is right, they pack medicine in the socket. It happens when a clot doesn't form. Make sure to follow all the post op instructions they give you. Hope you feel better soon!
tylenol is safe in pregnancy, but you defintely want to wait at least four hours if you can... six is even better.. taking it one time too close together should be ok... but make sure from now on you wait at least four.. also you can ask your doctor to give you lortab (vicoden) if its bothering you that much - that has tyelnol in it, but also hydrocodone, which is safe in pregnancy (as long as its not taken too much!) also if its really bad you may have a dry socket, which nothing helps with those but getting packing in there-i think! of course taking no medicine at all is always better than taking it, but sometimes its necessary! GOod luck! ick i hate dental procedures! ahh!!
