Antibiotics are widely prescribed to control bacterial infections. Sometimes they are given before a medical or dental procedure, to prevent a possible infection from occurring; this practice is called "antibiotic prophylaxis." In the recent past, physicians and dentists advised that people with certain medical conditions - including a number of heart problems and several types of bone or joint replacements - should always take antibiotics before many routine dental procedures. Today, their advice may be different.
A growing body of evidence now indicates that far fewer patients need to take this preventive step than was previously thought. As a result, the guidelines for prescribing antibiotic prophylaxis have recently changed - and they may do so again in the future. Why are the recommendations changing - and what do you need to know about taking antibiotics before coming to the dental office?
