The condition of your oral health can offer many clues about your overall health. For example, most of us know ulcers in the mouth can appear due to a low immune system. Oral health and overall health are more connected than you might realise. Your mouth is full of billions and billions of bacteria that are mostly beneficial.

Paying attention to your dental hygiene and health, especially your gums, may be more beneficial to you than you realise. A healthy mouth doesn’t just mean a sparkling smile, a healthy mouth may keep your whole body healthy too. However, experts emphasise that the keyword is may. Cardiologists (heart doctors) and periodontists (dentists who treat gum disease), have long researched the link between dental health and heart health.

The World Health Organisation states on its FACT SHEET that “Oral diseases share common risk factors with the four leading chronic diseases – cardiovascular diseases, cancer, chronic respiratory diseases and diabetes – including unhealthy diet, tobacco use, and harmful alcohol use. Poor oral hygiene is also a risk factor.”

Whilst the scientific research for the connection between oral bacteria and the development of these diseases is not fully determined, it still raises important questions about the role of “microflora”.

“Gum disease also has an inflammation component,” says Sam Low, DDS, associate dean at the University of Florida College of Dentistry in Gainesville, and president of the American Academy of Periodontology. Gingivitis, the beginning stages of gum disease, occurs when gums become inflamed and bacteria overtake the mouth. “The bacteria we find in gum disease we also find in blood vessels that are going through atherosclerosis” says Low. (Atherosclerosis, or hardening of the arteries, is a condition in which plaque builds up inside the arteries. Plaque is made of cholesterol, fatty substances and calcium.)


The mouth is an entry point for pathogens as it comes into contact with bacteria every day without us realising it! We come in contact with pathogens everyday. Most of the time our body’s immune system destroys them before they can cause harm.

A pathogen is anything that causes a disease. Pathogens include:

  1. Bacteria. A group of microscopic organisms that are capable of reproducing on their own, causing human disease by direct invasion of body tissues. Bacteria often produce toxins that poison the cells they have invaded. Numerous bacteria also live in harmony with the body and are necessary for human existence, such as bacteria that aid in digestion in the gut. Bacterial diseases include “strep”, tonsillitis, pneumonia, and meningitis.
  2. Viruses
  3. Fungi (example: athlete’s foot)

The microorganisms in our mouth are the first line of defence against pathogens and an important part of our immune health. If a healthy balance of oral bacteria is affected by stress, illness or antibiotics, it can quickly lead to problems such as throat infections, ear infections and bad breath. 

BreathActiv probiotics will naturally colonise in the mouth. Once BreathActiv bacteria take up residence in your mouth, it has been scientifically shown that they will then offer long-term protection from a number of harmful bacteria and diseases.

BreathActiv also supports gum and tooth health, naturally and safely whitens teeth and freshens breath.
