What is a bone replacement graph? I have periodontal disease and have had the scraping and cleaning treatments done but since this disease caused my teeth to start seperating (little triangle spaces in between teeth) I have asked the dentist about getting crowns, vaneers, ect...to fill in the gaps but he said that there wasn't enough gum in between teeth to hold the crown in very long...so what do you think he would have to do? Is this what you had to do as well with the bone replacement graph or is this something entirely different. Thanks for any advice and I wish I could tell you something as well on your question but as you can see...I am in no way entitled to give any advice on teeth problems
