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.

错误的刷牙方式可能引发致命心脏问题。据英国《每日邮报》报道，残留于口腔内的细菌会造成致命的血块，这种情况可能诱发罕见的感染性心内膜炎。

一旦进入血液，细菌就会导致血液凝结。而对于血块中的细菌，免疫系统和抗生素均无办法。

2010年发布的一项研究也指出，口腔卫生差也会造成其他问题，比如心脏病发作和中风。
