how tf do you guys brush your teeth?

Dental hygiene is probably one of my greatest struggles—it's a miracle my teeth haven't fallen out yet, and I wouldn't be surprised if my braces are the only thing left holding them in place. Brushing is a big struggle, and idk what to do about it. One big particular issue i find i have is how long the taste of the toothpaste lingers and how I keep having to spit after, so I tried just brushing without in hopes it would help me be more consistent and ultimately be better... but I don't think it's really working. Frankly I'm terrified of getting permanent damage (aside from what I've probably already suffered) and I just don't know what to do. Is there like, tasteless toothpaste, or a really effective cleaning mint, or like a little gnome I can hire to keep my teeth clean? Idk what to do.
