Hi. Welcome to Chat Doctor . I have gone through your query and can understand your concerns. As per your complaint it seems there is formation of DENTAL ABSCESS due to infection from tooth reaching below the root tips of the tooth leading to pus formation. At times the pus and infection perforates the bone and accumulates in the soft tissues leading to swelling. Antibiotics can take a longer time to resolve infection and swelling, and you should take him to the dentist back so that he can take an x Ray and if tooth can be saved he initiates a Root Canal Treatment under local anesthesia so that a channel is formed for pus Chat Doctor.
