I use sensodyne toothpase and their new toothbrushes which get round my tight wonky teeth nicely, and waxed floss - I can't get anything else between my teeth as they are very tight.
I also used hot water with a bit of salt dissolved in it as a mouthwash if my gums get sore - I get food lodged in certain places and if my gums get sore, they swell up and keep it there. I used to have this problem with my wisdom teeth. Once the swelling goes down, I can clean them properly.
The problem with the floss is cleaning the mirror afterwards

(Also, I have become very adept at dealing with the floss over the years - it takes a lot of practice to get to the point where it cleans efficiently but does not cheese-wire the gums)
