Is it safe to have an injection for a dental filling while you are on antibiotics?

Generally, it is safe to have an injection for a dental filling while you are taking antibiotics. Antibiotics are used to treat infections, and the injection used for dental fillings is typically an anesthetic that numbs the area around the tooth being worked on. There is typically no interaction between antibiotics and local anesthetics.

However, it is important to inform your dentist about any medications you are taking, including antibiotics, before your appointment. Your dentist can provide you with specific guidance based on your individual circumstances and medical history.
