  • Hey there!

  • Welcome to Life Noggin.

  • You know those nights where you're lying in bed and realize you forgot to brush your teeth

  • and you go, "Do I really need to get up?"

  • Well, skipping one night wouldn't be the end of the world

  • but what would happen if you never brushed your teeth?

  • Like, ever?

  • Well, it's actually a lot worse than you think.

  • Mouths are dirty, dark, moist places, full of breeding bacteria.

  • In fact, one mouth can contain more bacteria than there are people on Earth!

  • When we brush our teeth, we're scrubbing away that excess bacteria,

  • and also food particles and plaque.

  • When we don't brush, all that gross stuff just continually builds up in our mouths.

  • Our immune systems go into overdrive to try to clear it all out but they can't.

  • And the consequences to not brushing at all could be much worse than the cavities or gingivitis

  • our dentists warn us about.

  • But before we get to that, let's start with the basics.

  • Plaque is a film that coats your teeth and feeds on leftover sugars in your mouth.

  • It produces an enamel-eating acid that gnaws away at your teeth,

  • leaving holes known as cavities.

  • Uncontrolled plaque can also cause inflammation of the gums, aka gingivitis,

  • discolored teeth, oral abscesses and horrible bad breath.

  • When bacteria really starts to build up,

  • you increase your risk of developing something called periodontitis,

  • which is the erosion of tissue, gums and bone that support your teeth.

  • The mouth just can't hold the teeth anymore so they fall out.

  • This is the leading cause of tooth loss and if you never brushed your teeth,

  • you'd probably have a lot less chompers than the rest of us.

  • Now this may seem like your run-of-the-mill dentist schpeil but this stuff can get serious.

  • The bacteria in your mouth is both good and bad,

  • but things like MRSA and Staphylococcus aureus can thrive in there.

  • And if you never brush your teeth, harmful bacteria like these

  • can worm their way under your gums and get access to your blood.

  • Yikes.

  • Bad oral care has been also linked to serious diseases such as heart disease, COPD, pneumonia,

  • and endocarditis, which is an infection of the inner lining of your heart chambers or valves.

  • So if you're leaving your mouth to fend for itself,

  • you'd better watch out for these conditions.

  • A few controversial studies have also claimed to have found

  • links between bad oral hygiene and things like dementia and erectile dysfunction!

  • And remember how not brushing erodes areas of your mouth?

  • Studies have shown that

  • those pockets may serve as reservoirs for HPV and cancer-causing substances.

  • Thankfully now, we have modern toothbrushes and floss to protect our pearly whites,

  • but in ancient times, people chewed on twigs to clean their teeth,

  • then scraped the surfaces with the frayed end.

  • So yeah, things have gotten a lot better.

  • How many times a day do you brush your teeth?

  • I wanna know if any of you have been slacking.

  • Let me know in the comment section below,

  • or tell us: What should we talk about next?
