Just that really. I remember as a teen I used to be able to bite through cello tape when wrapping things, no problem. Then I had braces in my mid teens and I can no longer do this. I've just been wrapping something now and couldn't find the scissors so in a rush just tried to bite some tape off the roll but couldn't seem to do it so asked my partner instead. It feels odd like my teeth are weak or something. Some one else I know mentioned they have the exact same problem as me a while back. I also mentioned it to my dentist and they just shrugged it off. Has anymore else experienced this? Aibu to think braces made my teeth weaker?
