Is it normal to share toothpaste?
Mostly.Normal for most people
Yes, sharing a tube of toothpaste is common, especially in a household. Just don’t share toothbrushes or let the bristles touch the tube opening.
Lots of people share a toothpaste tube with family or a partner. It’s generally fine as long as everyone squeezes toothpaste onto their own brush rather than pressing the bristles against the opening.
Sharing a toothbrush is different: keep those separate. If the tube-sharing thing grosses you out, having your own is also completely reasonable—this is mostly a preference, not a big deal.
