Failing to brush your teeth properly could potentially lead to fatal heart problems, as bacteria loitering in the mouth may cause life-threatening blood clots, which could trigger a rare condition called infective endocarditis, the Daily Mail reported.

Once in the blood, the bacteria can prompt the blood to clot. Hidden inside the clots, the bacteria are shielded from the immune system and antibiotics.

A 2010 study found poor oral hygiene is linked to an increased risk of other conditions such as heart attacks or strokes.

錯誤的刷牙方式可能引發致命心臟問題。據英國《每日郵報》報道，殘留于口腔內的細菌會造成致命的血塊，這種情況可能誘發罕見的感染性心內膜炎。

一旦進入血液，細菌就會導致血液凝結。而對于血塊中的細菌，免疫系統和抗生素均無辦法。

2010年發布的一項研究也指出，口腔衛生差也會造成其他問題，比如心臟病發作和中風。
