Proper mouthwash is a game changer.

Had problems in my 20’s (30 years ago), old dentist: “use mouthwash 2-3x a day, and not that newfangled nonsense, I mean Listerine. Yea, it tastes awful, but it works.” hahaha

Dammit if he wasn’t right about my issues at the time.

And modern electric toothbrushes are a game changer. Not like the truly electric (as in you plug it in) when I was a kid. I think improved brush heads and especially the built-in timer make the difference.
