I didn’t brush my teeth as a child and teen because I had energy issues and I struggled to actually do them; I still struggle to do it today.
I rarely floss because it seems like a lot of work for seemingly little gains.
I got plaque again after getting teeth cleaned some weeks ago. I guess my teeth is screwed…
I suggest you take a look at water flossers. Flossing, while a lot of work, is sometimes necessary when you’ve eaten something stringy that gets stuck between your teeth. Having it be stuck between your teeth for a day(s) will result in cavities and inflammation.
