performed a root canal, after 2 days pain got worse. could not contact because office was closed on weekend. suffered with pain & called mon am only to get an antibiotic i had already been taking. was told to call back thurs, still suffering from pain. called thurs to request a new antibiotic and was explained the aftercare & pain for 20 mins only to be refused another antibiotic. i know my body and i know i was not reacting 100% to the antibiotic originally prescribed which is very possible i now have an immunity to it. still in pain, still not satisfied, never returning or recommending!!
