15 Weird Facts You Didn’t Know About Your Mouth

9. There’s more bacteria in your mouth than there are people on this planet.

Seriously, there are more bacteria in your mouth than there are people. There are 7.5 billion people on Earth but there are over 20 billion microbes living in your mouth at any one time. Puts bacteria into perspective, doesn’t it?

10. Lips are one of the most sensitive body parts

Along with your fingertips, your teeth have the highest number of touch receptors in the body and more of your brain is dedicated to receiving touch signals from them.

11. Our ancestors needed wisdom teeth

We may remove our wisdom teeth at the drop of a hat nowadays, but our ancestors needed these teeth to survive. They needed the extra molars to chew the roots, nuts and meat that were a part of their diet. Our modern diet doesn’t make them necessary today.

12. You need saliva to taste

Saliva is what breaks down your food into the compounds that your tastebuds can pick up on, this is why we need it to be able to taste. No saliva, no tasting delicious food ever again, so thank goodness for saliva!

13. The bacteria in your mouth helps to prevent cavities.

The billions of microbes living in your mouth might seem strange to think about, but you need them to keep your teeth healthy. The good bacteria living in your mouth stop bad bacteria from growing and attacking your teeth, causing cavities. As if that weren’t enough, they’ll also keep bad breath at bay! Thanks bacteria!

14. Your lips can reveal how fertile you are

This one only applies to women, where full lips indicate that the woman has high oestrogen levels in her body. Lipstick enhances the colour and shape of your lips, which is what makes them look more attractive to potential mates.

15. Your tongue is the only muscle in your body that’s only attached at one end.
