I'm nearing 50 and am considering getting braces. As I understand it, there are three kinds: 1. Standard grillwork 2. Invisiline 3. Behind-the-teeth braces I'm intrigued by Invisilines, but I'm afraid that they might make talking difficult. As a teacher, I not only have to talk all day, I often have to project my voice. The last think I need is to spit out my orthodonture at the very moment I'm trying to sound authoritative. Behind-the-teeth braces also sound like a good idea, but I don't see how they would leave sufficient room for one's tongue. I'm afraid that wearing them would necessitate lisping, and if standard braces have anything going for them, it's that people can SEE them and will then understand why the wearer is lisping. I'd like to hear from anyone who has had personal experience with any of these options as an adult. Thanks.
