Penicillins in dentistry

Oral penicillin has been mentioned in textbooks as the first choice for normal patients. But since amoxicillin – a penicillin analogue – is better absorbed and more durable, dentists are more likely to prescribe it for their patients. Co-amoxiclav is a combination of amoxicillin and clavulanic acid and a good option for treating patients with weak immune system.

Penicillin injection is usually not recommended due to its possible dangers. Many people have died from severe hypersensitivity to penicillin over the past few decades. Since penicillin can be substituted with efficient drugs, its injection is recommended only in special cases and by the treating dentist.
