I had a root canal filling on Wednesday at my local dentist. He supplied me with an  amoxicillin prescription for 3 250 mg daily which I started Thursday night as I had pain and swelling around the site of the filling inside. On Thursday I developed some cheek swelling that side which has slowly got worse despite the amoxicillin although now I do not have pain around the tooth but could not bite on it.
