Hi. I have a large cavity in my first top left-hand molar, and a large portion has broken off. A dentist I saw said I need a root canal but I cannot afford it. I’m taking ibuprofen and Aleve in an effort to stay ahead of the pain which is working for the most part. I also have a prescription for hydrocodone but I’m trying to make it last. However, a tooth on the bottom of the same side is starting to hurt like crazy, a deep, sharp pain down in the bone that even the hydrocodone seems unable to alleviate. In addition my jaw and cheek bone on that side hurts including the joint. Are these pains the cause of my cavity or perhaps is there something else going on? Are teeth nerves sufficiently intertwined that pain caused by one tooth can be felt at another location? Oh, I’m also taking penicillin just in case there’s an infection. Thanks.
