I feel your pain. I am 44 and due to a sinuse infection I had when I was just 25 (infection lasted 2yrs) I lost all my teeth by age 27 (infection ate the roots of my teeth and left most my jawbone mush). I have worn dentures sinse, well 1 year ago my jaw snapped. I have seen dentist and oral surgens, both agree I should have bone grafts done but none have faith in it helping much. My current dentist will do 4 post at a huge discount (compared to everyone else's prices it is) $4000. I have insurance, but they consider "post" for dentures to cosmetic. Insurance will help with bone graft but still would not cover the cost for post. I am a single dad and my kids live with me, I cannot afford even the discount price. I cant afford to take a trip to Mexico and would be too nervouse of the outcome if I did go. I am too looking for a Govt grant, denture school, anything that would help. I have to keep my lower denture in, even at night, because I clinch my jaw alot. The last time it snapped, I was eating a peice of pizza.
I hope you find some help, just know you are not alone.
