Most people with heart disease do not need antibiotics before dental work
Only a small group of people with heart conditions need antibiotics before a dental visit. The American Dental Association explains that the American Heart Association (AHA) limits this to people at the highest risk of a serious heart infection called infective endocarditis. Most people with heart disease, high blood pressure, stents or a heart attack in their history are not in that group.
That said, never decide this alone. Your cardiologist knows your exact heart condition. Ask them whether you need antibiotics, and tell your dentist what they say.
The group that needs antibiotics is small, and the list is short and specific. The rest of us protect our hearts best by taking care of our gums every day.
What infective endocarditis is
Infective endocarditis is an infection of the inner lining of the heart or the heart valves. It is rare, but it is serious. Germs from the mouth can enter the bloodstream, especially when gums bleed, and in a vulnerable heart they may settle on damaged tissue.
For decades, many heart patients were told to take antibiotics before dental visits. Research changed that picture. The AHA found that the risks of antibiotics, including allergic reactions and drug-resistant germs, outweigh the benefits for many patients who were once advised to take them.
A few facts help put the risk in context. Bacteria enter the bloodstream during everyday activities like chewing and brushing, not only during dental procedures, especially when gums are inflamed. That is one reason the AHA focuses on daily oral health rather than on a single dose before a visit.
Most heart problems, such as coronary artery disease, a past heart attack, a stent, bypass surgery, a pacemaker or high blood pressure, are not on the highest-risk list for endocarditis prevention. If you have any of these, you still need to tell your dentist, since your medicines and your health history matter during treatment.
Who needs antibiotics, based on AHA guidance
According to the ADA's summary of the AHA guidance, preventive antibiotics are recommended before certain dental procedures only for people with conditions like these:
- An artificial (prosthetic) heart valve, or a heart valve repaired with prosthetic material
- A history of infective endocarditis
- Certain types of congenital heart disease, such as unrepaired cyanotic defects or repaired defects with prosthetic material in the first six months
- A heart transplant with a valve problem
What changed in 2021
The AHA published an updated scientific statement in 2021. The ADA reports that it made no changes to the 2007 recommendations about who needs antibiotics. It reaffirmed that preventive antibiotics are for a small subset of patients. The statement also dropped clindamycin as the alternative for people allergic to penicillin or ampicillin, because it can cause more severe reactions, including a serious intestinal infection called C. difficile.
The 2021 update was endorsed by other medical groups, including the Infectious Diseases Society of America, according to DentistryIQ.
If you are not sure whether your condition is on the list, ask your cardiologist to write it down for you. Keep the note in your wallet or phone so every dentist you see has the same information. Antibiotics for people with artificial joints are a separate question, so ask your orthopedic surgeon and your dentist.
Which dental visits count
Even for high-risk patients, antibiotics are only advised before procedures that manipulate the gum tissue, the area around the tip of a tooth's root, or that perforate the lining of the mouth. Examples include extractions, deep gum cleanings, and some surgeries. Routine numbing injections, X-rays, taking out stitches, and placing braces are not on that list.
Your dentist and cardiologist will go over your plan. If you do need antibiotics, the usual approach is one dose, taken before your appointment.
If you need antibiotics and forget to take them before the visit, tell your dentist as soon as you remember and ask what to do. Do not just skip the conversation.
The real prevention: a clean, healthy mouth
The ADA stresses that good oral health matters for everyone. Daily brushing, flossing and regular dental care lower the amount of germs that enter your bloodstream every day from chewing and brushing. For people at high risk of endocarditis, this daily protection matters even more than a single dose of antibiotics.
Healthy gums bleed less. Treating gum disease early can lower the chance of germs entering your blood. So keeping up with cleanings is not optional if you have a heart condition.
Daily habits matter most: brush twice a day with fluoride toothpaste, clean between your teeth, replace your toothbrush every three to four months, and see your dentist on schedule. If your gums bleed when you brush, do not stop. Bleeding is a sign the gums need more care, not less.
What to tell your dentist about your heart
Bring this to your appointment:
- The name of your heart condition and any heart surgery or devices, such as a valve, stent, pacemaker or defibrillator
- Your cardiologist's name and phone number
- Every medicine you take, especially blood thinners
- Any chest pain, shortness of breath, dizziness or swelling in your ankles
- Any past reaction to antibiotics

Common questions
Do I need antibiotics before the dentist if I have a stent?
Usually not. The AHA reserves antibiotics for a small group of high-risk patients, and stents are not on that list. Confirm with your cardiologist.
Do I need antibiotics with a heart murmur?
Most heart murmurs do not call for antibiotics. Ask your cardiologist about your specific diagnosis.
What is the danger of skipping antibiotics when they are needed?
The risk is infective endocarditis, a rare but serious heart infection. That is why high-risk patients should follow their cardiologist's advice.
Is it safe to have a dental cleaning with heart disease?
Yes, for most people. Regular cleanings protect both your mouth and your heart health. Tell your dentist about your condition and medicines.
Why did the advice change?
Researchers found that the risks of antibiotics, like allergic reactions and drug resistance, outweighed the benefits for many patients. The AHA narrowed the list.
Who decides if I need antibiotics?
Your cardiologist and your dentist decide together, based on your heart condition and the planned procedure.
