I have just turned 18 and have been through the first stage of my treatment at my orthodontists. It was a twin block brace, which was in for 14 months and corrected my overbite. I was happy to get out, unfortunately I didnt realise I would have a wear a holding brace with a big plastic block which covers the roof of my mouth and hangs below my front teeth. This brace will then be fitted with a fixed brace to straighten them while maintaining my gums position. I find this brace incredibly intrusive and I would like to know if this treatment is completely necessary. If theres any surgery that can be done and what are the expenses if so.
