I am at least the 5th generation with this disease. I elected to have my teeth pulled, but now I am facing sinus and bone augmentation to replace bone loss. The good news is I found a medical code that may cover the expenses through ICD-9 code 520.5 Hereditary disturbances in tooth structure, not elsewhere classified (this specifically lists dentinogenis imperfecta. If only someone had shared this with my 20 years ago, I could have saved so much money and aggravation.
If insurance doesn't cover costs, Dr. Zhang in Anaheim, CA is beyond affordable when it came to implants. I spent over a year researching and visiting Mexico, and Dr. Zhang was the most affordable and did great work.
