Get a good electric toothbrush. That will help you make sure you’re brushing for a reasonable amount of time and is much more effective than a traditional brush. It’s worth the investment.

If you don’t want bad breath but are on a time crunch, I recommend using a metal tongue scraper. A lot of the bad breath comes from the white on your tongue, so scraping it makes the breath better. I also recommend gently flossing at least once a week, especially if your teeth are jagged (speaking from unfortunate experience)

Op didn’t ask how to brush his teeth. Op asked how to get motivation to while being depressed. Honestly, u got me beat in that question. I’ve gone a week without showering from being so depressed lol. I would try to brush at least once a day if not every other day as long as ur teeth don’t feel gross. Chew gum and use mouth wash so your breath isn’t reeking that’s pretty easy enough. Also, maybe keep your tooth brush somewhere it’s not out of reach

I find daily care to be one of those things that you can half ass. Not all the time but if you’re having a bad day just use one of those disposable brushes. Get you a water flosser and electric toothbrush. On good days or if you need a pick me up take the time to do everything. Self care is different for everyone shower sitting down. If anything a good mouthwash can help you freshen up
