hello...last year i had a root canal on a tooth , never had any problems. two weeks ago, i had that tooth worked on to rebuild it so that i could get a crown. when the dentist was drilling i felt a pop and what felt like something draining/ It was the strangest thing! I swear I could feel the air when he used that device to dry the tooth off. He filled the tooth and when he was done I told him what I felt, he said he was sure it was nothing. However, for the last week or so every time i bend down or tilt my head back i get tons of pressure in that tooth. It will even ache on it s own and not because i m using the tooth to eat. Does it sound like he drilled into my sinus cavity and will it heal on it s own? Should i be antibiotics to speed up the process or prevent further injury?
Root canal done tooth can never give and sensation to cold or hot. Moreover the pain and pressure felt on tilting the head clearly indicates that the pain is due to irreversible pulpits and a root canal treated tooth does not have pulp in it. So my friend the pain you are feeling is due to the tooth adjacent to the one which already s been root treated. Tell your dentist to take a fresh x-ray of that area including adjacent teeth. There is a possibility that you will need another RCT in different tooth this time. Take care.
