8 Negative Effects of Poor Oral Hygiene – Some of These Will Shock You

poor oral hygiene

Your teeth play a huge role in the first impression you make on people. Every time you talk to or meet someone new, your teeth tell a lot about you to the person you are in front of. Poor oral hygiene can lead to a lot more than just bad breath and decaying teeth.

In this article, we are going to talk about the main negative effects of poor oral hygiene. Some of these you will probably already know, and others will probably shock you.

It is our aim to show you how important your oral hygiene is, because there are some pretty serious health risks associated with bad oral hygiene.

Lets take a look at some of the most common negative effects of poor oral hygiene.

8 Negative Effects of Poor Oral Hygiene

Stained Teeth

This is one of the obvious negative effects. Poor oral hygiene will usually first lead to stained and discolored teeth. In some cases this is simply due to the enamel of your teeth becoming stained. This is called extrinsic discoloration.

Whether it be from coffee, tobacco products, red wines, sodas, or fruit drinks, your enamel becomes stained. This type of stain can usually be correct with a high quality home teeth whitening kit, or some high quality teeth whitening strips that will whiten your teeth pretty fast without paying a lot of money.

The other type of stained teeth is called intrinsic, and this is when the dentin in your teeth becomes discolored. Dentin is the layer right below your enamel. This type of tooth stain typically cannot be corrected because there is not a teeth whitening product on the market that can whiten dentin.

Tooth Decay

This is another obvious negative effect of having poor oral hygiene. Here is the process of how tooth decay happens. Plaque in your mouth contains bacterias. Those bacterias feed off sugars that you eat. That bacteria then creates harmful acids. The harmful acid then eats away at and erodes your tooth’s enamel and eventually your dentin. This is what tooth decay is.

Tooth decay if left untreated often leads to pain and can even lead to tooth loss.

When you have poor oral hygiene, you are allowing this process to happen on a daily basis. On top of that, you are letting this harmful acid sit on your teeth and damage them for a longer period of time than if you have good oral hygiene.

Gum Disease

This is the last obvious negative effect we will discuss, then we will move onto the less obvious negative effects that may shock you.

There are two main types of gum disease. The first is Gingivitis. Gingivitis is the milder form of gum disease and causes your gums to bleed easy, become inflamed, and red. In most cases Gingivitis is not painful and can be corrected with the help of a dentist and a good oral hygiene routine.

The second type of gum disease is called Periodontitis. This is a more severe form of gum disease and happens when Gingivitis is left untreated. Periodontitis sets in when the plaque on your teeth begins to spread down below your gum line. Once this plaque gets down into your gums, it begins to create toxins which eventually irritate your gums. These toxins trigger a chronic inflammatory response within your body and your body essentially turns on itself. Once this happens, the different tissues and bones in your mouth that are meant to give support to your teeth begin to break down and become destroyed.

This then leads to the separation of your gums from your teeth and these pockets or separations become infected. The gaps or pockets then get deeper and more and more tissue and bone becomes destroyed. As a result your teeth can become loose and you will eventually begin to actually lose your teeth.

This can all be prevented with a good oral hygiene routine.

Heart Disease and Stroke

This might be a negative effect that you do not know about. Yes, it is true that bad oral hygiene can lead to heart issues. Studies have shown that those with bad oral hygiene can be two times more at risk of developing heart disease.

This occurs when the plaque and bacterias enter your body through your gums. They then get into your blood stream and have the capability to begin to clog arteries as well as clog the blood vessel that sends blood to your brain.

This puts you at a much higher risk of a stroke or heart disease.


Another negative effect that may shock you. Bad oral hygiene, specifically if you have gum disease, can eventually lead to dementia. Recent studies have found harmful bacterias from the mouth in the brains of those with dementia.

Scientists believe that dementia from poor oral hygiene is due to the excessive exposure of the bacteria to the brain. The body’s immune system then reacts to this bacteria in the brain and results in nerve cell death, which in return can lead to memory loss or dementia.


Here is another negative effect in which you may not have known. Severe gum disease has the ability to make your blood sugar rise. Studies have concluded that over 95% of people who have diabetes also suffer from some type of oral disease.

Respiratory Issues

Those who have periodontal disease are at a higher risk of respiratory complications. This is because the harmful bacterias in your mouth can get into your blood stream and eventually end up in your lungs.

This can cause major respiratory problems such as chronic pneumonia or acute bronchitis.

Pregnancy Issues

Poor oral hygiene can lead to several pregnancy issues including infertility problems, premature birth, underweight baby, and even infection of the newly born baby.

Many of these complications happen because the bacteria in the mothers mouth is transmitted via her blood and amniotic fluid in her womb to the baby.

Studies have shown that bacterias in the mothers mouth are often found in her stomach as well in the baby after complicated births.

Conclusion on The Negative Effects of Poor Oral Hygiene

As you can see, your teeth are not only an important part of your image and impression you give off, they are also important to your overall health. Some of the negative effects we shared are pretty obvious, but others you may not have known about. We hope this article has educated you a little about the less obvious health issues associated with poor oral hygiene.

This is why it is important to have a good oral hygiene routine that you practice daily in order to keep your mouth and teeth as healthy as possible.
