They probably have to readjust your bite. Or move your other teeth back in order to make room for your front teeth to straighten.I got my deep clean on half my teeth yesterday. It went well other then the Novocain. Apparently I had a reaction to the epinephrine as I started shaking and my heart started racing. It only lasted a few minutes but that was long enough. The next half she will use another kind. Monday I start the process to get braces... never thought I’d do something like that but my front teeth started shifting about 9 years ago and it bothers me. They used to be perfectly straight naturally. Apparently you can’t just get them for the front teeth, you have to have the whole set![]()
I hope for your sake that you don't have to wear headgear or elastics like I did.
