Dentists don't want you to know that a small wire brush will be both longer lasting and cheaper than a toothbrush and never go soft!
Pretty sure you only want to use soft bristles thought. Anything else will help damage your teeth.
I was going to continue my joke but nah, I'm out. Don't use wire brushes you'll destroy your teeth. And stay away from sweets and booze and drugs!
I think most people would stop right after slicing open their gums.
