Amy, if you have dental insurance, they will most likely be responsible for flouride trays, at least mine was. Dental also paid for teeth extracted, EXCEPT for those pulled during the actual cancer surgery, and that was paid by Medical. Read your policies carefully. If you do not see exclusions for things denied, you can contact your state insurance commission(er). Called something different in every state, but you can ask for assistance and/or arbitration. Sometimes the insurors have to be reminded to toe the line and live up to the agreements they made when collecting your premiums. The last thing you need right now is yet another thing to straighten out, but if you are persistent, this situation can be corrected. You just need some muscle behind you. It is an unfortunate fact, but insurance companies save money every time they can intimidate someone into accepting their verdict. If you think you are right, do not back down. This is really a case of squeaky wheel getting the grease. I worked for an international insurance brokerage for decades, and know whereof I speak. I also interceded on behalf of my parents, and myself, so it can be done. I wish I could help you too. Go get 'em!
