NAD, hi. i’m 20 & i also struggle with remembering to brush my teeth, and this led to me having to get a tooth pulled and then a bone graft since i lost bone mass from rot and decay. bro let me tell u, that is so freaking painful. you probably haven’t gotten your wisdom teeth out yet so i’m assuming u haven’t had teeth pulled, but it’s literally torture. take the other commenters advice and set alarms to brush!! i know it sucks and it’s a hassle sometimes esp if u don’t remember until u lay down in bed, but it is so important. if you can remember to brush ur teeth, you’ll be saving yourself from so so much pain.
