If a person notices an unusual taste in their mouth, often described as sour it could be a warning sign.
Gum disease or periodontitis could lead to heart disease, as a build-up of ‘bad’ bacteria in the mouth can enter the bloodstream.
Other gum disease symptoms include bad breath, tooth loss or inflamed gums. Professor Adam Taylor from Lancaster University said: “The heart, so integral to life.
“It sits in its protective cage in the chest, going about its work without any external sign to the owner.
“The mouth is full of bacteria, both good and bad.
“The bad bacteria can enter the bloodstream from the mouth and cause inflammation in the blood vessels, which can lead to cardiovascular disease.”
