11 Slightly Horrifying Facts That Will Stop You Biting Your Nails

Unless you love sucking up 10 million germs a day, ofc.

1. There are all kinds of deeply wretched germs crawling under your fingernails.

Fingertips are hives of nastiness, and are home to various types of bacteria, fungus, and YEAST (eww). One particularly prevalent germ found under nails is Staphlococcus aureus, which can cause a load of crazy skin infections like boils and abscesses. Mmmm, oral boils.

2. When you suck and chew on your fingernails, they become an even greater bacterial paradise.

Back in 2007, Turkish scientists tested 59 people to see whether nail biting had any real effect on transporting bacteria to the mouth. They swabbed each person’s mouth for saliva to check for diarrhoea and vomiting bacteria such as Escherichia coli and many other nasties starting with E. And guess what? Seventy-six per cent of those who bit their nails tested positive, compared to just 26.5% of non-biters. So if you don’t want to spend half your life shitting for Britain, you might want to take your fingers out of your mouth, now.

3. If you bite your nails, chances are that you’re already causing dental damage.

4. You're more likely to grind your molars into dust at night.

5. Brace-wearing biters run the risk of causing unprecedented damage to their chompers.

Dr Ansa Akram, a clinical lecturer in orthodontics at the University of Bristol, told BuzzFeed that nail-chewing brace wearers are treading particularly risky water. Not only does the habit put the brace at risk from breaking, but it can also cause or increase root resorption in teeth undergoing orthodontic treatment, which IRL means that your body's own cells start to EAT AWAY AT THEMSELVES and dissolve tooth structure.

6. Nail biting can make you prone to grim gums...

Chowing down on your fingertips can cause a load of accidental trauma – that's right, TRAUMA – to your gums. One particularly horrendous case study mentioned in a report by Dr Carlene B. Krejci mentioned a kid who suffered from gingival (gum) swelling under one of his teeth after years of sticking his craggy, half-eaten fingernails under the gum tissue of his tooth. Turned out, there were SIX FINGERNAIL FRAGMENTS STUCK UNDER HIS TOOTH.

7. It can also help cultivate skunk breath.

The same unpleasant report also found that nail biters were prone to halitosis, aka highly disgusting breath. There's plenty of bacteria living in your mouth and most of it is meant to be there, but if you keep sticking your fingers in your mouth you're going to introduce a ton of gross germs too.

8. Your fingertips can soon turn into a pus bath.

Nail biting and picking at the skin around the nail often go hand-in-hand. And while that might feel like a great way to while away the time, having acute infective paronychia isn't. It's caused by Staphylococcus aureus bacteria getting into small, open sores, and results in pools of pus forming around the nail. Basically, it's like finger herpes, which is actually caused by the cold sore virus. It can be cured by pills, but sometimes it has to be surgically drained. :O

9. Nail biting can even lead to ORAL STIs. NO JOKE.

So it turns out that this horrible habit can even GIVE YOU HERPES. It's pretty rare but there have been occasions where STIs have resulted in oral lesions (lip blisters) thanks to a transference of bacteria from finger to mouth. Stay woke.

10. Nail varnish is essentially poison and should not be chewed.

11. And finally, those nails might NEVER GROW BACK.

Chronic nail biting can damage the nail bed, which, when exposed, leads to the irreversible shortening of nails. In other words, biting far enough down the nail bed means that no nail can latch on in future and so nails remain as stumps FOREVER.
