How Does Oral Health Affect Your Systemic Health?

Posted on July 27, 2023 6:10 pm

Disease-causing bacteria can enter your body through the mouth, before penetrating the respiratory and digestive tracts. Hence, without proper oral hygiene, this roll-on effect may have a greater impact on systemic health when oral conditions such as tooth decay and gum periodontitis occur.

As if this isn’t alarming enough, certain medications such as antihistamines, painkillers, and antidepressants can reduce saliva flow—further reducing your natural ability to reduce microbes from multiplying in your mouth, and ultimately, your body.

What diseases can be linked to poor oral health?

Cardiovascular disease. Studies suggest that heart disease, clogged arteries, and stroke may be linked to inflammation and infections that oral bacteria cause. 

Endocarditis. Bacteria or other germs entering your mouth can spread through your bloodstream and attach themselves to certain areas in your heart, causing an infection of the inner lining of its chambers or valves.

Pneumonia. Similar to endocarditis, certain oral bacteria can multiply all the way to your lungs, causing pneumonia and other respiratory complications.

Birth and pregnancy complications. Periodontitis has been linked to cases like low birth weight and premature birth.

Can certain conditions worsen oral health?

Certainly—individuals who suffer from health complications are more likely to develop gum diseases. Some examples include:

Diabetes is one of the many culprits of gum disease. Studies show that gum diseases are more frequent in individuals with diabetes, mainly because it weakens the body’s resistance to infections. Furthermore, they have a harder time controlling their blood sugar levels due to impaired insulin functions.  

HIV and AIDS. Searing mucosal lesions on the gums and tongue are common in people who suffer from this condition.     

Osteoporosis. This bone disease can contribute to periodontal bone and tooth loss. Drugs used in its treatment can also damage the bone jaw.

Depression and anxiety. Oral disease can stem from poor mental health due to neglecting or avoiding hygienic routines.

Teeth and gum diseases can worsen or lead to many other conditions like eating disorders, rheumatoid arthritis, immune system disorders, and even certain types of cancers. Medications treating these conditions can also affect the individual’s oral health. 

How to improve oral care for your general health

While some systemic diseases can be caused by other external factors and are sometimes inevitable, having a solid oral care routine can optimise your body’s defense against germs. 

  • Brush your teeth at least twice daily for two minutes using a soft-bristled toothbrush and a therapeutic toothpaste. Oradex Periodontal Toothpaste is formulated with hyaluronic acid to promote periodontal tissue regeneration, panthenol to strengthen gum tissues, and fluoride to remineralise the tooth’s enamel. 
  • Floss regularly.
  • Use mouthwash after brushing and flossing your teeth. We recommend using Oradex Everyday Antiseptic Mouthwash for effective, long-term maintenance and protection against gum diseases.
  • Replace your toothbrush every three to four months or when the bristles start to look worn out.
  • Schedule regular dental checkups.
  • Avoid smoking and excessive alcohol consumption.
  • Limit sugary foods and drinks.
