This is odd to admit but I went a year without brushing / flossing my teeth, then went to the dentist and asked about my plaque build-up. Negligible. When I told them about this experiment they were disbelieving. I attribute it to my strict diet at the time: Keto, no products with added sugar. Few fruits. Mostly vegetables, fats, and some meat. Certain foods would cause bad breath so I limited consumption of those at key times.
