The 700 Species in Your Mouth: Tame Them or Risk Disease

Your mouth is home to approximately 700 species of bacteria. When managed, they are harmless. But when neglected, they can multiply and create a pathway to systemic diseases, including diabetes and heart problems. Your toothbrush is the only thing standing in the way.
A dental specialist explains that brushing’s purpose is to “interrupt a biological chain reaction.” This reaction starts when bacteria form sticky plaque, trigger inflammation, and enter the bloodstream. From there, they can travel to the heart, liver, and pancreas.
This bacterial migration is what links oral health to heart disease. The chronic inflammation from your gums can cause atherosclerosis, the hardening of arteries. This strains the heart and, over time, wears down its defenses.
It also creates a “vicious cycle” for diabetics. High blood sugar weakens the gums, allowing these 700 species of bacteria to cause infections. The toxins from these infections then make it harder for insulin to work, raising blood sugar further.
The solution is to keep your “gatekeeper” in top condition. Replace your toothbrush every three months. An old brush with frayed bristles is an ineffective tool against 700 species of bacteria. It can’t clean properly, allowing plaque to build up and start the inflammatory cascade.
