Composite Buildup

[XxHaimBondxX]

My daughter is 5 years old and during the recent visit to our dentist, we were advised she has a large overbite and were recommended a procedure called Composite Buildup. From what I understand, the doctor will apply the filling-type material to the teeth on both sides of her jaw and this will cause the front teeth to grow larger and correct the overbite. At the time I thought it was a great idea and have scheduled the procedure. After coming home and doing some research I could not find a single reference to the above procedure, moreover, I found online articles about the harmful chemicals the filling materials contain, such as BPA, which effect behavior and development. I myself have an overbite, which after wearing braces for 5 years, was not corrected entirely. Never bothered me at all. Any input appreciated.
