Colleen,
Yes I had my entire lower jaw replaced. But don't fret I am just fine. I have past the five year mark. I've changed my eating habit due to necessity. It is amazing how a person can adapt to a new situation when there isn't any choice. I am very healthy, have regained all the lost weight, and am strong. I don't have a PEG and all is well. So if I can do it so can you!
