Is it normal to share toothbrushes?
Depends.It depends
Some people share a toothbrush in a pinch, but it’s not a great habit. Toothbrushes can pass along germs, so it’s better to keep yours to yourself.
It happens—especially between partners or when someone forgets to pack one—but most people would rather not share. A toothbrush picks up saliva and germs, and sharing can also expose you to traces of blood from irritated gums.
If you shared one once, don’t panic; just rinse it well and use your own next time. Keeping separate toothbrushes is the easy, less-germy option.
