Have you tried putting your toothbrush and toothpaste in the shower? I've struggled with brushing my whole life and this is the only thing I've ever tried that actually worked. I also put a brush and paste at every sink but the only time I can ever actually manage to brush is in the shower.

If you're like me, then some time in your thirties. I didn't brush from early teens through until then - I had several abcesses and needed seven teeth removed, including my top fronts. Turns out I had undiagnosed autism, depression and low self image. Now I do brush, and it's just a case of forcing myself to adapt to a routine. Even keeping some flouride mouthwash handy for a quick swill every now and then helps a bit. Hope you find your way.

I was like you, the transition was not easy, but what helped me was to brush my teeth when I already went to the bathroom to pee. This meant that I rarely brush my teeth at the same time. But I do it every night now. This also helped me reduce my snacking after 20:00. Because I didn't want to snack after brushing my teeth. I convinced myself I was going to do this and ever since I only missed 2 nights. What also helped is using a tracking app where I could check it to "gameify" it.

It gets mighty expensive.
