25 Reasons You Should Brush Your Teeth

Posted by on February 10, 2012

Besides complicating your social life, neglecting to brush your teeth can land you with more than just a couple cavities. It could actually stop your heart. We’re not joking. Gum disease has been linked to an increased prevalence of numerous other conditions such heart disease, stroke, diabetes, and bronchitis. But how? Because your mouth is full of bacteria, if you have poor dental hygiene those bacteria can potentially make their way into your bloodstream and thus infect distant parts of your body. So, with that said, here are 25 really good reasons you should brush your teeth.

Save Money

Okay, so it’s pretty obvious that if you don’t brush you’ll probably lose your teeth, but by the time you get to the bottom of this list you’ll see that brushing twice a day can potentially save you much more than a couple hundred bucks on a cheap pair of dentures. It can save you tens of thousands of dollars in health care over the course of your lifetime and potentially save your life as well.


Smell good

While we know it sounds obvious we just wanted to be clear, your mouth smells bad because of bacteria and chewing gum does not kill bacteria. At least not to any significant extent.



Caused by plaque build up on your teeth Gingivitis often leads to swollen gums that bleed when you brush them. Ironically, there is only one way to prevent this…to brush them.


4 out of 5 Americans have it

Your chances of actually preventing Gingivitis look fairly bleak. With 80% of Americans afflicted by some form of gum disease it quickly becomes clear why dentistry is such a lucrative profession. But gingivitis is only the beginning. Eventually you’ll find yourself with some much worse…



You thought swollen, bloody gums were bad? Well, that gingivitis will eventually spread and you’ll start losing the alveolar bone around your teeth, followed by the teeth themselves. Couldn’t get much worse than that could it? Oh it certainly could. Periodontitis, doctors have found, is often a gateway to many other much more serious complications. Let’s start with…



Your mouth is one of the primary ports of entry into your body. Food, bacteria, almost everything inside of you passed through it at one point or another. This means that when something as critical as your mouth becomes infested with harmful bacteria (as it would when you have gingivitis or periodontitis) it will inevitably affect the rest of your body. Take this as an example…


Trench mouth

Coined in the trenches of Word War 1 where it afflicted many soldiers, this is essentially an extreme form of gingivitis. Your mouth becomes so overrun with bacteria that they often spread into your cheeks, lips and jaw bones. This however, is just the beginning.


Heart Attack

If your gums are bleeding and your mouth is overflowing with plaque and bacteria, it will eventually make its way into your bloodstream. Unfortunately this means that it will inevitably pass through your heart, and plague in your heart is never a good thing. Besides causing heart attacks though, this rogue bacteria can also lead to…



In a mechanism very similar to what happens in the heart, the bacteria can also spread through the blood stream and into your brain. So, not only can it increase you chances of having a stroke but it can also lead to…



Poor gum health increases your risk of developing dementia by almost 30% to 40%. There are several theories about the exact mechanism but hopefully you can see the correlation. Remember to brush your teeth and it will help you remember everything else as well.


Alzheimer’s Disease

Yes, we know that this is a form of dementia, but just in case anybody reading this wasn’t sufficiently scared into brushing by everything above, we thought we should throw this one in for good measure.



Evidently those same bacteria that can destroy your heart and brain are also capable of decreasing the effectiveness of the insulin in your bloodstream. Eventually this will lead to difficulty in controlling your body’s blood sugar and then, at the end of the day, to an increased risk of type II diabetes.



So apart from that nasty, mouth dwelling bacteria seeping into your bloodstream and slowly contributing to the death of your vital organs, there is another mechanism by which they can be swept deeper into your body…inhalation. As soon as those fine droplets from your mouth settle into your lungs they can easily start causing problems and bronchitis is only the beginning.



Smoking is bad for you but smoking and not brushing your teeth is bad for you. It’s not just the smoke in your lungs that can cause Chronic Obstructive Pulmonary Disease, but also the tobacco destroying your gums. Like a double edged sword it increases your chances of having COPD twofold.



Even if you don’t smoke, that bacteria in your mouth can still lead to some nasty consequences. Just like with bronchitis and COPD, it has also been known to cause pneumonia. But apart from not breathing, there are still a couple other things that failing to brush your teeth can cause. Something like…

    Thank you very much for sharing such an important info. It will definitely help everyone to improve on their habits.

  • HELP!!

    note to self: mouthwash BURNS!! seriusly !

    • Katie

      Use mouth rinse with no alcohol (like Listerine Zero) to stop that painful burning sensation. Little known fact- the alcohol in most mouth rinses is there only for that “tingling” sensation that many people associate with that fresh breath feeling! Personally, I can’t stand that burning/tingling sensation myself!

  • HELP!!

    …….nooooooooo! MY LIFE IS OVER! I HAVE GINGIVITIS!! as soon i finised i IMEDEATLY brushed my teeth! this scared the crap out of me!

  • taylor

    Wow this site its saying the same thing about using modern tooth paste. So who is right? You who says to use fluoride and not get any health problems. Or them who use natural toothpaste so they dont get a mental disease from fluoride? Weird how things contradict them selfs base on scientific facts…on the natural part i know for sure its true but do you know for sure about your source? was it college haha please…

  • TAylor

    Lol where are your scientific studies? This is a load of #$^@, funnyhow toothpaste has florine in it and they “scare” us into brushiing our teeth. Does marijuana make you a drug craze person? haha hell no that what they wanted you to think thought. but we can think that without medical studies right? I guess not so dont belevie this #$^@ lol the first ones ya logical yes…but the last ones make me laugh. Also you have a international business degree, what the #$^@ does that have to do with any thing, especially on this article about medical health.

    If you have the right bacteria in your diet you wouldn’t get this. Your mouth get over run because you drink /eat pasteurized everything and not enough fermented foods. And dont forget the antibiotics you take and never replenish your Bactria count after wards. So ya I guess you would have all this if you where relying on modern medicines and processed food..

    I feel bad for the people that read stuff on this internet and instantly believe it. Go read some conspiracy Papers, will you believe those? Go to you tube, there community is critical, so if its got good thumbs up it generally good.

    Yes, it is a very good article. However I would like to read a bit more of every problem that you mentioned. What should I do?

    • http://jcgator1.wordpress.com Juan Castillo

      Hi Wanna!
      The best thing to do is just to go on google.com and type in the issue you are wanting more information on. There are a huge amount of medical/dental websites that are both authoritative and reliable offering information on just about any problem or issue people face today. I can’t really mention any site of the top of my head, but if you type your question into the google search engine, it will give you a whole list of sites you can check. Hope this helps.
