Hello everyone!
I had my braces taken out about four years ago and the orthodontics had placed a metal retainer behind my bottom front teeth. I noticed that there is this hardening, white solid stuff underneath the retainer. I've tried flossing, using a toothpick, everything to get it out but it seems to be permanent...
can someone please help me out to what it might be?
sorry, if it's not so descriptive! :/
& thank you very much!
