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.
Wife and I have had our Sonicare toothbrushes for something like 15 years and never had trouble finding replacement heads. In the event Phillips stops making them I’m certain 3rd parties will still make them.
must depend on model because one was definately soniccare.
