Did you realise that pneumonia and oral health can be linked? We were surprised too! Vhi Chief Dental Officer, Dr Gina Kilfeather, shares four health conditions that are impacted by poor oral health and bacteria in the mouth.  

You’ve heard the old saying that your eyes are the windows to your soul, but did you know your oral health provides a window to your overall health? Your oral health can offer clues about your physical health, and problems in your mouth can impact the rest of your body.

The role of bacteria

Like other areas of the body, the mouth has lots of different bacteria, most of which are harmless! Some of these bacteria can be damaging for things like our throat, oesophagus, stomach, and small intestine, however. The good news is, good oral healthcare (and our body’s immune system), usually keep these bacteria under control. If you don’t have proper oral hygiene, bacteria can reach higher levels and cause problems. It can lead to oral infections, like tooth decay and gum disease.

Studies suggest that severe gum disease (called periodontitis) might play a role in some diseases and health complications. And certain diseases, such as diabetes, can lower the body’s ability to fight infection, making any oral health problems even worse.

Poor oral health could potentially contribute to various diseases and conditions, including:

• Cardiovascular disease

Bacteria normally found in the mouth has been found on the plaque that builds up in our arteries, increasing our risk of heart disease, clogged arteries and potentially, stroke. Bacteria from the mouth can also travel to the lining of the heart causing a serious infection called infective endocarditis. The research into this important connection is still ongoing. 

• Pregnancy and birth complications

Periodontitis (a severe form of gum disease) has been linked to some complications for both mother and baby, such as premature birth and low birth weight. While this is a scary correlation, remember that periodontitis can be avoided with a good oral health routine. And, if you do develop periodontitis, your dentist will be there to help you with treatment and care.

• Pneumonia

It’s possible for certain bacteria in our mouth to move down to our lungs. This can increase your risk of pneumonia and other respiratory diseases or infections.

• Diabetes

Diabetes type 1 and type 2 both put your gums at risk by reducing your body’s resistance to infection. Gum disease appears to be more frequent and severe amongst people that have diabetes. Research also shows that people who have gum disease have a harder time controlling their blood sugar levels. Regular periodontal care (deep cleaning to prevent and treat gum disease) can improve diabetes-related gum issues and help control your diabetes.

Remember, the issues I’ve described can be avoided by keeping up your good oral health routine. I’ve covered all the above to equip you with more knowledge when caring for your gums and teeth. Your dentist can provide answers to any questions you might have about the links between oral health, physical health and lifestyle.
