Your Oral Health

Why do some people take antibiotics before some dental procedures?

Any time there is bleeding in the mouth, oral bacteria can enter the bloodstream. The body’s immune system usually then destroys the bacteria.

In people who have certain heart diseases or deformities, however, the bacteria may settle on abnormal heart valves or heart muscle tissue that has been weakened by an existing heart problem or heart surgery. In these cases, the bacteria can cause a serious inflammation of the heart valves or tissues called bacterial endocarditis.

To reduce the risk of bacterial endocarditis, people with certain heart conditions will be given one dose of an antibiotic to take approximately one hour before dental procedures that are likely to cause oral bleeding.

Be sure to tell us if you have a heart condition. We will need to note this information in your patient record and may want to speak with your physician further.

The recommendations regarding antibiotic prophylaxis to prevent bacterial endocarditis are developed by the American Heart Association. The recommendations related to dentistry are approved by the ADA.

Important note: The recommendations are meant to help us or your physician to determine whether you could benefit from antibiotic prophylaxis. However, they do not override the professional judgment of your doctors.

I have a heart murmur. Should I take antibiotics before seeing the dentist?

Not everyone who has a heart murmur is at risk for bacterial endocarditis. Your physician or cardiologist can tell you if you need to take antibiotics before certain dental treatments.

Even if your physician says antibiotic prophylaxis is unnecessary, you should tell us about your heart condition and your physician’s recommendation. Your dentist may want to note this information in your patient record or speak with your physician further.

Can medication use affect my oral health?

Yes, medications can have oral effects. Be sure to tell us about any medications that you are taking — including those you purchase over the counter.

Dry mouth is often a side effect of medications such as antihistamines, decongestants, pain killers and diuretics. Some of the common problems associated with dry mouth include a constant sore throat, burning sensation, problems speaking, difficulty swallowing, hoarseness or dry nasal passages. Left untreated, dry mouth can damage your teeth. Without adequate saliva to lubricate your mouth, wash away food, and neutralize the acids produced by plaque, extensive cavities can form.

We recommend various methods to restore moisture. Sugar-free candy or gum stimulates saliva flow, and moisture can be replaced by using artificial saliva and oral rinses.
