Failing to brush your teeth properly could potentially lead to fatal heart problems, as bacteria loitering in the mouth may cause life-threatening blood clots¹, which could trigger a rare condition called infective endocarditis, the Daily Mail reported。

Once in the blood, the bacteria can prompt the blood to clot². Hidden inside the clots, the bacteria are shielded from the immune system and antibiotics³。

A 2010 study found poor oral hygiene⁴ 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。
