Toothbrushes should definitely be off limits.
Falling head over heels for your soulmate has countless benefits — including spending all your time together. Still, there is such a thing as being too close. And if you’re double-dipping with any of the following products, chances are you’ve already hit that boundary.
Using the same tube of toothpaste is fine, but a toothbrush? Some couples rationalize this habit by saying that they kiss, so sharing a toothbrush isn’t a big deal — but do you really want the bits of food that your partner enjoyed earlier hanging out in your own mouth?
Even worse: You could pass along viruses to each other (think strep throat), says dentist and founder of Creative Dental Care Dr. Joseph Banker.
When you shave, razors can make nearly invisible nicks in your skin, meaning the razor has your blood on it whether you realize it or not. And according to dermatologist Dr. Mona Gohara, MD, that means you can get any one of these infections (staph, molliscum, warts, viral infections, bacterial infections, fungal infections) if you’re using the same razor. So while it may be inconvenient to keep separate shaving tools in the shower, it’s a much safer option.
