Taking good care of your teeth will not only help you have a great looking smile, but it will also keep you healthy. But, do you ever wonder what happens if you never brush your teeth?

Your mouth is a gateway to your body, and it’s not very pristine – it’s dirty, dark, and full of breeding bacteria. In fact, your mouth contains more bacteria than there are people on earth.

When you brush your teeth, you are removing those excess bacteria, but also food particles and plaque. But, when you don’t brush, these bacteria continually build up in your mouth. And as a result, your immune system goes into overdrive to try to clear it all out but it can’t. So the consequence of not brushing your teeth at all is much worse than the cavities or gingivitis your dentists warn you about. But, before we get further, let’s start with the basics.

So what is plaque?

Plaque is a slimy, sticky films that constantly grows on your teeth, and it contains millions of bacteria. When you eat, the bacteria in plaque use leftover sugars in your mouth to produce enamel eating acid that gnaws away at your teeth. And with repeated attacks, the bacteria cause the enamel to break down, eventually leaving holes in your teeth known as cavities.

Plaque, if not removed regularly by brushing or flossing, can also cause inflammation of the gums, known as gingivitis, discolored teeth, oral abscesses and bad breath. Moreover, as bacteria continues to build up, your chance of getting periodontitis – a more severe form of gum disease – increases. Periodontitis causes tissue, gums and the bone that supports your teeth to disintegrate.

As you know, most bacteria in your mouth are quite harmless, but things like Staphylococcus aureus and MRSA can thrive in there. Methicillin-resistant Staphylococcus aureu, commonly referred to as MRSA, can cause infections in different parts of the body including the skin. What makes MRSA different from other forms of staph is that it cannot be killed by a number of commonly used antibiotics. So if you never brush your teeth, harmful bacteria like MRSA can worm their way under your gums and get access to your blood line.

Poor oral hygiene has also been linked to pneumonia, dementia, heart disease and endocarditis – an infection of the inner lining of the heart chambers. A few controversial studies have also claimed to have found links between bad oral hygiene and erectile dysfunction. Studies have also shown that periodontitis may promote the growth of human papillomavirus (HPV) and cancerous cells in the mouth.

Well, everyone’s health is different. Someone with good genes could go without brushing for over a year and not face any of these serious health problems, but their teeth would still be covered in plaque. And their breath would smell horrible.

So how often do you brush your teeth? Do you floss every day? What’s the longest you’ve gone without brushing your teeth? Let me know in the comments below.

  1. I used to go to the dentist to remove plague from my teeth about twice a year and then I made the mistake of deep cleaning them because I had signs of gingivitus and did so about two times. I began loosing teeth because they started to wobble so I extracted them and did without.
    I began to realize that nature probably knew best so since I was 60 years old and didn’t socialize much and no longer had sex with my wife I stopped brushing my teeth and my bad breath is horrible but I only lost one additional tooth on the left side of my mouth because I was chewing mainly on the right and not left.
    I no longer have gingivitus and the plague buildup which hardens pops off my teeth when the buildup is too great. There are good and bad bacteria in the mouth and the good ones are taking good care of my teeth without brushing.
    I no longer have inflamed gums and am very happy with my oral health. It seems that nature knows best although my teeth are not very white but I smoke and drink coffee which probably has discolored them to some extent.
    I wouldn’t advocate this nature knows best approach to young humans having sex and being socially active but it has worked miracles for me. I also don’t eat sugar or eat sweet fruits and I have had no recent cavities. I now think that the dental profession is largely a large expensive cleaning ripoff without proven clinical results for not brushing teeth. Thanks for the article but I am a contrarian retired human who feels that nature knows best and smelly bacteria in your mouth are good for your teeth because they are a cleanup crew in the long duration.

    1. I recently had a dental appointment about a week ago and had the gap between my front incisor filled. With cleansing, x-ray and all, it cost me around $300. Well, I hope I don’t make the same mistake you did. Thanks for the comment, Uldis. It was worth the read. :P
