Dental disease is usually caused from bacterial infections. Take periodontal infection for instance. When the gums become inflated, bacteria may enter the bloodstream and circulate throughout the entire body. If a person is a congenital heart attack sufferer, and if the bacteria get into the heart, then it will lead to endocarditis which may be fatal.
牙病通常是細菌引起的，以牙周病患為例，牙齦發炎時，細菌會隨血液循環到全身各處；如果他同時是先天性心臟病患者，細菌跑到心瓣膜，會導致心臟內膜炎，就有致死的可能。
