Toothbrushing

Hello! As an autistic person with depression i have a really hard time brushing my teeth. It used to be easier as a kid because my mom is very particular about oral health and would make sure me and my brother would always brush before bed. Although I did often gag and hated the texture of tooth brushes and toothpaste and still do, I wouldn’t complain. She stopped reminding us and expected us to do it on our own the more we grew up and by the time i was in middle school there were only occasional reminders around dentists appointments. As a teen and as an adult now I struggle to remember or get motivation to brush my teeth on my own. I have to use kids sized toothbrushes still because any sizes bigger irritates me too much. I don’t floss because of similar sensory issues. It’s quite frustrating when people notice that my teeth are more yellow and point it out, it makes me feel insecure and embarrassed. I do still try to brush my teeth at least once a week with water most of the time whenever I get the motivation to force myself to do it and I occasionally use teeth whiteners because my teeth are stained yellow. I drink a lot of tea so between that and not brushing as much as i should, i have yellow teeth even when i do brush from the staining.

Does anyone have any tips on how to make brushing my teeth easier? Maybe a way to help with the sensory overload of it?
