6 Dangerous Consequences of Poor Oral Hygiene

Despite the fact that there is a lot of information about the importance of proper oral hygiene, many people still skip flossing and tooth brushing regularly. However, this neglect can significantly affect your oral and overall health together. If you still think that toothbrushing is not important, check these six dangerous consequences of poor oral hygiene.

1. Bad breath

Poor oral hygiene is considered one of the most common causes of bad breath (also called halitosis). If you don’t brush your teeth, dental plaque and food particles can accumulate on your teeth and rot. Moreover, they can become a comfortable environment for various bacteria. 

If you have bad breath, it can significantly affect your social and personal life. The main problem is that you may even not know that your breath has an unpleasant odor. That’s why it is better to brush your teeth regularly and check your breath. The simplest way to do this is to lick and smell your wrist. It is much easier to perceive the odor of the breath on the skin.

2. Tooth decay

As mentioned above, a lack of oral hygiene contributes to the plaque and food debris accumulation on your teeth, especially near the gumline. The reality is that bacteria that live in your oral cavity eat plaque and food leftovers and produce acids. These acids tend to soften your tooth enamel and cause tooth decay. 

If left untreated, tooth decay can progress and affect the inner layers of your teeth. This can cause severe pain and discomfort. That’s why regular dental check-ups (even if you don’t experience any symptoms of oral issues) are essential.

3. Gum disease

Gum disease is a condition in which the gum tissues become inflamed, red, and swollen. Despite the fact that gum inflammation can be caused by several factors, poor oral hygiene is considered the most common cause. If you don’t remove the dental plaque, it hardens and turns into tartar. 

At the primary stage of gum disease (gingivitis), you can experience gum bleeding, redness, swelling, and gum recession. At the advanced stage (periodontitis), you may experience a toothache, gum pockets, and loose teeth in addition to the symptoms listed above.

4. Teeth loss

Teeth loss can also occur as a result of poor oral hygiene that caused periodontitis. This condition leads to receding gums that can’t hold teeth in their places. If the teeth fall off, it is essential to replace them with dental implants as soon as possible. Otherwise, your bite and facial symmetry can change. 

5. Tooth abscesses

Poor oral hygiene can cause a tooth abscess. This is an inflammatory process that affects the root of the tooth. A tooth abscess is usually accompanied by acute pains that are aggravated by eating or drinking. The other symptoms include redness, induration, and swelling of the affected area.

In most cases, bacteria infect one tooth, but with advanced disease, suppuration can spread to several teeth. The onset of an abscess is always palpable, as it is accompanied by severe pain at the site of the lesion. Painkillers are not quite effective since they can relieve pain only for a short time.

6. Cardiovascular diseases

If you tend to neglect proper oral hygiene, you increase your risk of cardiovascular diseases. Bacteria that cause periodontitis may enter your bloodstream and move to your heart. When bacteria reach it, they can contribute to the development of atherosclerosis.


Atherosclerosis is a condition in which plaques develop on the inner walls of arteries. They may interfere with normal blood circulation and even cause a heart attack or stroke. You can also develop endocarditis which develops when the lining of the heart becomes infected.
