Hi I have dentinogenisis imperfecta as well and it has cost me and my family A LOT of money. I appreciate your advice about not wasting money but I really think that we need to petition for dental or medical insurance to cover more costs. I am very interested in heading up a campaign. It is crazy that we have a documentated medical/dental genetic disorder and no insurance company is wiling to help us. PLEASE write back with as many names of people in your family or you know that would be willing to sign a petition if I send one out.
