Hi. Welcome to HEALTHCARE MAGIC.. I have gone through your query and can understand your concerns.. As per your complain as you have infected molars and chest pain although there is a direct co-relation between the infected teeth which can lead to infection through blood reaching the endocardium [inner layer] and valves of heart and the condition is known as BACTERIAL ENDOCARDITIS but it is extremely rare to occur and cannot be concised to only chest pain as it has other symptoms also like heart murmurs, fever,chills,paleness,persistent cough etc.. Chest pain can occur due to a number of other conditions which can be related to digestive problems like acid reflux and gas, cadiovascular[related to heart] or respiratory tract disorders and you need to consult a Physician and get evaluated to get ruled out for the exact cause of pain.. As far as infected and broken teeth are concerned you should make an appointment with a dentist and get evaluated along with x-rays so that the exact status of the teeth is ruled out and treated by either filling of teeth but if infection is deep Root Canal Treatment can be done followed by capping of teeth.. Extraction may be needed in case where teeth cannot be saved and all the treatments will be followed by antibiotics and painkillers.. Hope this information helps.. If you find the answer helpful please give me a Five Star Review and click on found the answer helpful as a token of appreciation.. Thanks and regards.. Dr.Honey Nandwani Arora..
