We don’t recommend sharing a Shyn toothbrush handle both for sanitary and convenience reasons. It’s not hygienic to share a brush head with someone else, and swapping brush heads every time you brush wouldn’t be convenient. If you plan to share oral care supplies like toothpaste and floss picks with your household, we recommend one person subscribe to our Care Collection or Bright Collection, and the other subscribe to our Daily Collection in order to save on oral care products.
