Deep cavity on right bottom teeth, waiting to get root canal, fixed 2 cavities on top right, right tonsil and ear pain, is there a correlation here?

Yes, referred pain: Tooth infection have the capacity to produce constant boring referred pain to throat and ear. See your dentist ASAP to complete your treatment plan. Good luck!

Possibly: Referred pain from your recent and pending treatment can cause pain in your jaw and ear. Large fillings can inflame the nerves of the teeth. Speak to your dentist.
