Can anyone in the know explain this one? (Am seeing my dentist tomorrow but am perplexed). Have had niggling toothache for just over a week, but couldn't say specifically which tooth - one of the bottom big molars. Much, much worse Friday so made an appointment with my dentist tomorrow. Absolute agony Sat morning, still somewhere under back bottom molars but also in area between nose and top gums. Really painful. Rang NHS emergency dentist - a nurse diagnosed over the phone (!) that I didn't qualify for emergency apt as not severely swollen (silly me for saying 'a bit'), and I'm not taking enough pain killers. So I dutifully upped the painkillers. This morning the pain is shocking - under the TOP molars?! Bottom still aches but not as bad as the top ones. Still tender from nose in face, so I'm assuming sinus problem there. Why would the pain move - infection? Abscess? Will the dentist think I'm barking?
