The tooth brush – it is mankind’s tool for oral hygiene.

Those tightly packed bristles polishing enamel and cleaning gums.

A new study found there may be a good reason why sharing toothbrushes or your bathroom is a bad idea.

A study from the American Society for Microbiology found there’s a good chance your toothbrush contains fecal, and if you’re in a communal bathroom, like a college dorm, there’s an 80 percent chance.

“We’re all colonized with our bacteria and own guts bacteria. But you wouldn’t necessarily want somebody else’s guts bacteria in your body. It might cause food poisoning or they might have some resistant bacteria that they’re passing along to you. So it might be a bit of a problem in the future,” said Dr. Len Horovitz, an internist at Lenox Hill Hospital.

The study also found mouthwash, hot water and cold water don’t kill the bacteria.

So it’s best to always wash your hands and change your brush every three to four months.
