My teeth are all rotten because this has never been the case for me. It’s a chore that I have to actively decide to do every day, it’s a decision I have to make. There’s a phenomenon called “decision fatigue” that basically means you can only make so many decisions in a day before your brain just shuts down and refuses to make another one. Since neurodivergent people have to make more decisions and can’t rely on habits to lift decision making off of our shoulders we often hit that wall of decision fatigue and just kinda shut down.
If you add disincentives, like the fact that brushing your teeth is an inherently unpleasant thing to do, it can be very difficult to stick with it. Hence, rotten teeth and all of the associate health issues that come along with having rotten teeth.
