For me, it’s an electric toothbrush. It doesn’t matter if you go with Sonicare or Oral-B, once you start using an electric toothbrush, regular toothbrushes don’t ever feel like they clean your teeth properly. The smooth plaque-free top layer of your teeth that you can feel after using an electric toothbrush can’t be replicated with a regular toothbrush.
I have a set of small, palm sized stones I picked out of a local river. Nearly as good as my japanese whetstone progression set. :-) I seriously use the more, and my kitchen knives I can shave with. Feels so… manly :-)
Or you could just get a quick sharp and get on with life/cooking
