When you come for a dental visit, Dr. Tsang may ask many questions about your child’s medical history. Sometimes you wonder why she needs to know so many details?
It is important for her to understand the complete picture of your child’s current health status in order to provide the best care for your child. With a thorough understanding of one’s medical health, she will know what health interventions would be best suited for your child and will not precipitate any medical concerns your child may already have. One of the medical conditions that may really catch her attention is heart murmur.
What is a heart murmur?
When your heart beats, valves in your heart makes a “Lub-Dub” sound. A heart murmur is an extra or unusual whooshing sound that can be heard in addition to your normal heartbeat. Murmurs can be very faint to very loud. There are two types of heart murmurs; innocent heart murmurs (not threatening) and abnormal heart murmurs. An innocent heart murmur is not caused by a heart problem. It is usually caused by strong blood flow through your heart and can often occur in healthy children. Children who have an innocent heart murmur do not have to limit their physical activities and do not need any treatment. In contrast, children with abnormal heart murmurs may have congenital heart defects that are present at birth and are often accompanied by other signs or symptoms of heart problems.
Often, your doctor can tell right away whether a heart murmur is innocent or not by just listening with a stethoscope. On occasion, your doctor may request further testing, like an echocardiogram, to clarify whether it is innocent or abnormal. It is pertinent to distinguish what type of heart murmur your child has because there are some medications and procedures that are not suitable for someone who has a heart condition. Extra precautions (like taking an antibiotic) may be necessary before any dental procedures are safely carried out for these children.
What is infective endocarditis? How serious can it be? What is the potential link to dentistry?
It is an infection of the heart valves or lining of the heart when bacteria or other organisms enter the bloodstream. Once in the bloodstream, bacteria build up on a valve or the lining of the heart where damage may have occurred. The symptoms are fever, chills, fatigue, weakness, aching joints and muscles, shortness of breath, cough, swelling in the feet or legs, blood in the urine or the onset of a new heart murmur. Infective endocarditis is a rare complication that can occur after having dental work completed as bacteria in the mouth enter the blood stream during a dental procedure . If your child was born with a congenital heart disease, have artificial heart valves, or previous history of infective endocarditis, you should inform our dentists before any treatment as he or she may have higher risk for infective endocarditis after dental or medical procedures. One intervention that can be used to prevent this type of complication is the use of antibiotics before having any treatment completed. We follow the American Heart Associations guidelines for antibiotic treatment prior to dental procedures to prevent infective endocarditis. These guidelines support those individuals who are at highest risk of developing infective endocarditis receiving short-term preventive antibiotics before common dental or medical procedures. We also take the time to consult with your child’s physician before starting any treatment if there is need for clarification. Here are some easy tips for you to help us if your child has a cardiovascular history:
Ask your doctor for any special preparations
Inform our dentists and discuss with them your child’s condition prior to treatment
Know what medications your child is taking, if any. For example, some heart medications may cause excessive bleeding during dental procedures
Be prepared to give our dentist your doctor’s name and address
Be prepared to give our dentist permission to contact and consult with your doctor
