you will slow down your treatment as the front teeth want to align but your thumb will push them forward.
Awww....that's so cute.
Your thumb gets wet.
nothing. as long as you dont bite your thumb.....i have braces and i have sucked my thumb once or twice (occasionally i suck my thumb when im asleep) and nothing happened
One can only wonder why you would want to suck your thumb while wearing braces.
Doing so may make treatment time much longer. It is not worth it.
