The current theory is that bacteria present in infected gums can become loose and move throughout the body. The same bacteria that cause gum disease and irritate gums might travel to arteries.
Researchers are unsure what causes the bacteria to become mobile, but it has been suggested that bacteria can be dislodged and enter the bloodstream during tasks as simple as brushing, flossing or even chewing.
Research shows that risk varies according to the level of gum infection. The worse the infection, the more likely the bacteria are to become blood-borne. Infected gums bleed, making it easier for bacteria to enter your bloodstream. If bacteria become dislodged, the bacteria enter through cuts or sores in your mouth and travel to other parts of the body through your bloodstream. Once a bacterium reaches the arteries, they can irritate them in the same way that they irritate gum tissue. This could cause arterial plaque to accumulate in the arteries; which can cause hardening and affect blood-flow. Compromised blood flow to your heart can cause a heart attack. Also, arterial plaque can come loose and travel to other parts of the body. If blockage occurs in the brain, it can cause a stroke.
What should be done?
Best way is to maintain the oral hygiene. See your dentist at least twice a year for periodic maintenance. Any gums problems should be taken seriously. Although gum disease can often show few or no symptoms at all, watch for gums that are red and irritated, or gums that bleed easily. There are many new treatments available to control and help reverse gum disease. All the gum diseases are caused by the deposition of plaque. Proper brushing and flossing along with regular scaling is must for healthy gums.
