Is the Plaque in Arteries the Same As Plaque on Teeth?

The American Dental Association says there may be a correlation between dental plaque, the kind that collects on teeth, and arterial plaque, the kind that builds up in the arteries and can lead to heart disease.

Similarities

• Both dental plaque and arterial plaque are sticky, white substances found in the body. Both are unhealthy and should be avoided.

Dental Plaque

• The ADA says that dental plaque is a complex biofilm that is composed of hundreds of bacterial species. It forms in the oral cavity. Plaque leads to the formation of cavities.

Arterial Plaque

• The ADA says that arterial plaque is primarily composed of fatty material deposited in the inner wall of arteries. This type of plaque usually comes from cholesterol that comes from both food and the body's own production.

Correlation

• An article in the August 2006 edition of the New York Times stated that animal studies have shown that periodontal disease can lead to hardening of the arteries, heart disease and stroke, but there is no hard evidence supporting a direct link in humans. The article suggests that bacteria from dental plaque can emit substances into the bloodstream that contribute to a buildup of arterial deposits.

Prevention

• Brushing and flossing teeth can prevent dental plaque and may decrease the formation of arterial plaque as well.
