(* Mind voice – oops……now how to find out yaar!!!!)


Haha have you ever put your dentist to this situation!!!!! Ho please don’t… In this blog i will share a few things about the link between the heart disease and tooth related treatments.

There are three main reasons why your dentist is so much particular about knowing your heart condition if you have heart disease,

  • To get access on platelet and clotting factor mechanism
  • To have control over arrhythmia ( irregular or abnormal heart beat )
  • Role of micro organisms and infective endocarditis

To get access on platelet and clotting factor mechanism:

Blood thinner medicine are thumb rule tablets given to every cardiovascular complaint person. This helps to prevent from further clot formation on the blood vessels. But when the person wants tooth removal, intake of the same medicine will cause uncontrollable bleeding. It is to be noted that tooth and its supporting structures are highly rich in blood supply and it is difficult to control bleed when the blood clotting mechanism doesn’t respond properly.

At the same time it is highly NOT recommended to stop the drug just like that. Only the cardiovascular specialist knows the exact condition of every pumping organ. It is always advisable to have their opinion before taking the dental procedure. When the risk factor for the heart is more or on the moderate to severe illness condition, an alternative drug protocol will be recommended where an alternative antiplatelet drug takes up the role or the treatment regimen will be altered by the dentist. If the heart condition is under control, he may advise to go on with the procedure by stopping the drug for 5days or so…

* Person with the history of stroke or high blood pressure also will be prescribed with blood thinners. It is always better not to hide any medical history to the physicians.

To have control over arrhythmia:

As i said before, tooth structure is highly vascularised. In order to prevent excessive loss of blood during dental procedures, local anesthesia(LA) also contains a few percentage of “adrenaline ” in it. This helps for the constriction of the peripheral blood vessels thereby preventing from the excessive blood loss. Though adrenaline in the LA possess only very minimal percentage ( about 1:100000 dilution), for the person with uncontrolled blood pressure, this value is enough to shoot up the condition.

As like on blood vessels, the adrenaline has its own action on the pumping organ as well. Adr generally increases the heart rate and muscular contraction. So now when the person is having moderate to severe heart illness, this may worsen up. On such conditions LA without adrenaline is preferred if it is suggested by the cardiologists.


The role of micro organisms and the infective endocarditis:

It is well known that oral cavity is the main source of lodging micro organisms. Out of which, staphylococcus aureus and viridans streptococcus are the most predominant micro organisms which affect the inner wall of the heart called infective endocarditis. These bacteria quickly enters into the blood stream(bacteremia) to reach the heart valve. When the person is having heart valve defect or rheumatoid heart disease,  atmost care must be taken when going for the dental procedures. Antibiotic prophylaxis is a must for them. Without adequate precautionary steps, any procedures may end up into life threatening one.


Not any medical history should be taken for granted. It is to be understood that human body is a complex structure and everything is inter connected…
