At my first braces adjustment, he lectured me about my poor oral hygiene. I had been brushing too gently! He said not to be afraid of damaging my braces and that they are very strong. He then proceeded to grip my (very sore!) lower front teeth and shake my head from side to side, demonstrating just how mighty the braces are. He said that a toothbrush should last me a month, tops, and that by the end of the life of my toothbrush, the bristles should be smashed down and splayed out.
So, I went home and brushed more aggressively, per the insistence of my orthodontist.
And then spat out a piece of my braces.
Damn you braces. Damn you.
