7yr old with tooth pain I can't figure out

[AmandaBL]

I don't even know where to start with this.  My 7 year old has intermittent severe tooth pain in one of his lower side teeth (about half way back).  He had a filling in the tooth and complained of pain right away after the filling was done.  We took him in for a follow up and the dentist said everything looked fine. Pain continued, usually when he would eat or drink. We figured it was just because the filling was new and there was residual sensitivity.  Tylenol. Oragel. Pain.  He pulled out the filling while flossing one night. Filling was replaced, dentist said everything looked fine and the pain continued.  We had a root canal done on the tooth. He still says it hurts. He crys because it hurts so badly.  Sometimes I can distract him.  Sometimes I can't.  Took him in this morning and again she says everything looks fine other than his gums where he flossed around it last night thinking that he had food caught in between the two teeth. This is the same pediatric dentist my kids have seen for 13 years.  The 7 year old has had many fillings and has never had this issue with any prior filling. Am I missing something?  I am out of ideas and at the height of frustration. Help.  Did I mention my husband has cancer and our new dental insurance wont cover a pediatric dentist after age 6 so we had to pay out of pocket today? Oh yea.  That.  It's been a greeeeaaaat day :-)

Why don't you look for another dentist and take him for a second opinion? And if your insurance doesn't cover a ped dentist anymore, take them to a family dentist.
