British scientists have found that poor oral hygiene also increases the risk of heart disease.
Howard Jenkins, a scholar from the University of Bristol, said at the meeting of the society of General Microbiology held in Dublin, the capital of Ireland: “we now realize that bacterial infection is also an independent factor leading to heart disease. “
Jenkins said that there are more than 700 kinds of bacteria in the human mouth, most of which are harmless, but a small part may trigger a series of reactions that will eventually lead to heart disease and stroke.
“The mouth is probably the dirtiest part of the human body… If you happen to have a bleeding blood vessel on your gum, bacteria will invade the blood flow.”
Jenkins said that these bacteria will adhere to platelets and affect the smooth flow of blood. In addition, these bacteria also hinder immune cells and antibiotics from working.
According to the data released by the World Health Organization, heart disease causes 17 million deaths worldwide every year and is the number one killer threatening human life.
