Examine health crises worldwide, and you may expect to see issues like pandemics appear at the top of the list. If so, the reality might surprise you. According to experts, oral care - or lack of it - is the most neglected health challenge for the world's population.



Fortunately, unlike other health risks, oral problems have proven to be easy-to-access solutions. Read on to discover more about the link between oral health and overall health and what you can do about it.

Oral Hygiene Impact on Health

Most of us associate oral health with having strong teeth and a nice smile. However, what's happening in our mouths is more interesting than that, and there are some surprising links with what's happening in the rest of our body - particularly with our general well-being.


First, oral health, including the health of your teeth and gums, can be an indicator of an underlying condition, such as:


  • Nutrient deficiency
  • Diabetes
  • Cardiovascular problems
  • Digestion problems



For example, gum disease can have a widespread impact beyond the mouth and inflame other parts of the body. There is also a link to our mental health. A healthy, pain-free mouth boosts our well-being and confidence.

Gum Disease: The Health Impact

One of the most common types of oral health issues is gum disease, also known as periodontal disease. This is where plaque builds up where the teeth and gums meet, eventually creating inflammation in the gums. It is noticeable by redness around the gumline and sometimes bleeding when brushing.


Gum disease, left unattended, can start creating other problems in the body. The bacteria in the mouth can enter the bloodstream. This can create inflammation that can cause cardiovascular issues like clogged arteries and a higher risk of stroke.


Gum disease also makes it harder to control diabetes, as the inflammation can impact insulin, making it difficult for the body to manage blood sugar levels.



There is also some research linking gum disease and cognitive issues like Alzheimer's.

The Risk of Heart Disease

A big worry many of us face as we get older is the risk of cardiovascular disease. However, while we might monitor our weight and take up running, few of us consider whether our oral health is creating havoc that could one day lead to:


  • High blood pressure
  • Stroke
  • Heart attack


There is a link between poor oral health and cardiovascular problems. This is why good oral health (like flossing and brushing) should be as central to your personal care as your daily visit to the gym.



Regular dental consultation and prompt treatment for any dental issues are vital.

Diabetes Risks and Your Oral Health

If you are diabetic or prediabetic, you'll be well aware of some of the risks from your health diagnosis, like weight gain, atherosclerosis, nerve damage, and cardiovascular disease.


You'll also have a treatment plan, including a special diet and perhaps insulin. What may not be on your radar, however, is an improved oral care plan to minimize your health risks from diabetes.


The truth is that gum disease and tooth decay can lead to bacteria entering your bloodstream and causing extra issues with diabetic patients, like inflammation.


Diabetics can also experience a dry mouth and reduced saliva production. This saliva is the body's natural defence against cavities, putting you more at risk from dental complications.



Regular dental visits are crucial, and you should always let your dentist know about your diabetes or prediabetes as part of your medical history.

Oral Health and Your Immune System

Did you know that bacteria in the body can impact your immune system? It's something to consider if you regularly pick up cold and flu viruses.


Harmful bacteria and their role in inflammation can make your immune system weak because it is too busy dealing with the bacteria that have entered your bloodstream.



Oral care can do much more than keep your teeth looking great; it can also stop you from getting endless viruses.

Oral Health Tips

Good oral care is the first step in looking after your health and well-being. Your care routine must include:


  • Twice-daily brushing
  • Fluoride toothpaste
  • Antibacterial mouthwash
  • Flossing
  • Regular dental checks with your dentist
  • Professional teeth cleaning
  • Eating a balanced diet
  • Reducing your sugar intake
  • Reducing sugary drinks
  • Staying hydrated



Many of these are simple steps that are easy to incorporate into your routine. Nevertheless, small steps can have significant impacts, especially when it comes to your overall health.

Seeking Professional Dental Care

Sometimes, you need more than good oral care to maintain optimum general health. If a dental issue arises, you need to get prompt treatment. Signs of dental problems might include:


  • Persistent tooth pain
  • An accident resulting in a broken or chipped tooth
  • Bleeding or swollen gums
  • Bad breath
  • Loose teeth
  • Sensitivity to hot or cold food



If anything doesn't feel right, even if you have no noticeable toothache, it's always best to err on the side of caution and visit your dentist. They can rule out an issue or may spot the early signs of a problem and be able to treat it.

Oral Health and Overall Health: Are You Looking After Your Teeth?

Don't ignore the link between oral health and overall health. Early detection of dental issues can help you address risks and avoid any impact on the rest of your well-being, whether that's heart disease, diabetes, or even your mental health.
