I was blessed with a very serious problem with a tooth coming in the middle of my mouth, which required years of braces. We were very clear about asking if we could do both the top and the bottom at the same time, to decrease time and costs. He indicated that there was no reason to have braces put on the top, and I had bottom braces for over two years. Three months after the bottom braces came off (with very positive results), I was informed that I needed top braces.
