Antibiotics are medicines that may be prescribed to fight infections caused by bad bacteria. While antibiotics can be helpful, if overused, or used incorrectly, the bacteria may develop antibiotic resistance. In this case the use of antibiotics is no longer helpful to kill the bad bacteria and may even cause more harm by killing the good bacteria.
Most common dental procedures do not require antibiotics. However, based on your procedure and medical history, Dr. Zhugang Zheng may recommend an antibiotic. Always ensure you let Dr. Zhugang Zheng know about any medical conditions or changes to your health.
There are many circumstances during dental treatment where antibiotics are prescribed by dentists to prevent further infection (e.g. post-operative infection). The most common antibiotic prescribed by dental practitioners is penicillin in the form of amoxicillin, however many patients are hypersensitive to this particular antibiotic. Therefore, in the cases of allergies, erythromycin is used instead.
