It wasn't my decision to make - it was my Mom's. I had the old style Spanish Inquistion Full Metal with the little rubber bands. I remember the rubber hammer used to fit the metal bands around each tooth. I remember the constant ache. #1 worst thing is that it gave me Temporomandibular Jaw Disorders (TMD, TMJ Syndrome). At the time I didn't know that of course. Every time I would yawn, the left side would click. The jaw stopped clicking after braces off. I believe that is why at 49 I have three gold caps, and lost one tooth on the left side because of a misaligned jaw. The jaw stopped clicking. So if you are going to get em - get the invisible ones that are glued to front of teeth. If getting them prepare to pay top dollar for the best and forget the rest.
