>>212667994 (OP)Twice a day every day. Despite that they are rotting, I have visible brown spots and I have to get plaque taken off every couple of years. I brush thoroughly for 3 minutes. Teeth genetics in my family are very fucked though we have lost them by 30 historically for the most part, I am fortunate to have all of them at 22. My grandpa simply thugged out the pain till his gums hardened so he could use them to chew hard foods again.
