Dental Bacteria & Your Partner’s Toothbrush

It is a disgusting thought for most, but there are surprisingly couples out there who will occasionally use their partner’s
toothbrush. While we absolutely using partners toothbrushdo not recommend this from a hygiene perspective, it is important for you to know why.

Did you know that the human mouth is home to 19,000 to 26,000 different strains of bacteria? They live together in a biofilm – your plaque. These bacteria can then, of course, lead to tooth decay. The highest amount of bacteria exists on your toothbrush right you brush, but even after 24 hours, there will still be bacteria present. Are you grossed out enough yet?

When you are using someone else’s toothbrush, their bacteria then makes their way into your mouth because it sticks to their toothbrush. It can also be transferred by sharing water bottles, on lip gloss, and when you kiss.

So although you can’t take on their tooth decay (if they have any), the more bacteria that they have on their brush, the higher the chances of you having dental issues. No one needs more bacteria than necessary after all, right?!

Moral of the story: stick to your own toothbrush and practice good oral hygiene, for the benefit of both you and your partner.
