15 Weird Facts You Didn’t Know About Your Mouth


Your mouth is a weird place, but how many of us stop to think about the part of our body that we use all day every day? We use it to talk, eat, kiss, and that’s just for starters! If we really think about it, the mouth is a fascinating and unusual place, which is why we’ve found fifteen of the weirdest mouth facts that you never knew before.

1. Your tongue imprint is as unique to you as your fingerprint

No two tongues are the same and people can be identified by their tongue print in the same way as they can be identified by a fingerprint. Somehow, though, I can’t see it catching on as a way to identify criminals. I mean who goes leaving their tongue prints wherever they go?

2. Smiling boosts your immune system

Smiling makes your stress hormones drop, leading to an increase in the number of immune cells your body has available to fight off illness. So smile! It’s good for you!

3. The uvula, the strange bit of flesh that dangles at the back of your mouth, is used for speech.

Scientists have been trying to work out what the uvula is for ages, but most of them agree that it’s there to help with speech. They’ve come to this conclusion because it’s a body part that’s unique to humans and is capable of creating a lot of saliva very quickly, providing the lubrication our mouth uses to speak.

4. Kissing transfers over 80 million bacteria

A ten second kiss with can transfer over 80 million bacteria from you to your partner and vice versa! Research has also shown that if you regularly kiss the same person, the bacteria in your mouths become very similar. Something to think about before you kiss someone else!

5. Poor oral health can indicate poor physical health too

Unhealthy teeth and gums can indicate health problems like diabetes and heart disease. The state of your teeth may also show your dentist that you’re suffering from osteoporosis before any other symptoms show up.

6. You can’t smell your own breath

Forget your bad breath check, it’s completely pointless because you can’t smell your own breath. This is because the odours that come with bad breath only come out when you talk, so breathing into your hand and trying to check it out won’t work. You’re just going to have to ask a trusted friend to tell you if you’ve got the stink breath.

7. Men have longer tongues than women.

Men have longer tongues than women, even the world record breakers! The world record for the longest tongue measures in at 3.97 inches, whereas the world’s longest female tongue only reaches 2.76 inches. Guess that explains Gene Simmons!

8. Women’s tongues have more tastebuds than men.

Men might have longer tongues but women vastly outnumber men when it comes to taste buds. Studies at Yale have discovered that 35% of women are ‘supertasters’ which means they are more sensitive to certain flavours. Only 15% of men fall into this category. It’s also been discovered that women of childbearing age have a better sense of taste than women who are younger or older.
