I grew up in a lower middle class home with horribly bucked (?) teeth. My mother felt it was imperative that they be fixed, so I had braces from the age of 12 until 18. The reason for that inordinate amount of time was because I was constantly plagued with cold sores and many an orthodontal appointment was wasted because my dentist said he couldn’t work on me while any of those things were present. I’m assuming it was solely due to the pain factor inflicted on me, but I could be wrong. I know they are transferrable in certain ways, but I’m not sure if it could only be passed along touch though. Anyone else know?
Also, I LOVED having braces and hated it when they came off. My teeth looked a mile long to me and while I had them, it at least seemed like one thing made me different/special. (In every school I’d been in, both in Dallas and rural east Texas, I was the only one. It was kinda neat.)
