Scientists in their study has warned that certain types of mouthwashes can kill good bacteria in the mouth but by spiking the blood pressure it increases the risk of heart attacks and strokes. The study was published in the Journal free Radical Biology and Medicine on 28 January 2014.
Chemical Chlorhexidine in mouthwashes kills off good bacteria and allows the blood vessels to relax resulting in raising the blood pressure. Killing of all these bugs each day is a disaster as small rises in blood pressure have significant impact on morbidity and mortality from heart disease and stroke.
The study suggests that the mouthwash that contains 0.2 percent of antiseptic chlorhexidine in volume shortens the blood pressure by between 2 and 3.5 units of those who use mouthwash. For each two-point rise in blood pressure, the risk of dying from heart disease rises by seven percent and the risk of dying from stroke by 10 percent.
Chlorhexidine kills microbes that are needed to help in creation of nitrite, which is essential for blood vessels to dilate properly. The mouthwash causes to fall of nitrite-production in the mouth by over 90 percent and blood nitrite by 25 percent.
