Arestin is the antibiotic used to tackle periodontal disease (e.g. bleeding gums and tooth-bone loss). The antibiotic is used a follow-up to our Scaling & Root Planning procedure when patients still have pockets of hard-to-kill bacteria. We use this antibiotic to help prevent the need for surgery. ARESTIN is an antibiotic that is shaped like a cartridge and is placed in the mouth (in the area of active infection) to kill the bacteria that underlie periodontal disease.
