@graf @MaleGoddess @morgthorak they have recommended me to get a waterpik before, they're actually way cheaper than I thought. Haven't got one but it seems very convenient.
Also just chewing sugar free gum after meals can be good too. I try to do either that or brush with water real quick.
A lot of people sleep on flossing. Nearly all of my cavities started in between my teeth. It's important stuff, especially if you don't want to pay out the ass for it. Hindsight is 20/20 though :)
