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.
Can you just attach them anywhere? Do they shock you? Do they help nerve pain?
They do give little shocks, but it feels more like vibrations on the lower settings. I’m not sure about nerve pain, but it helps a lot with muscle aches.
