I have an abcess tooth, it just burst, dentist no in until morning.  My son has a prescription of Cephalexin (Kefolex) 500 mg capsules, he never took.  Thinking of taking them, as I am a bit "freaked" out right now, because a woman I work with son just died suddenly last tuesday from an untreated abcess that entered his blood stream and became sepsis.  Gargled with salt water so far.
HIT hank for asking to Chat Doctor I am sorry for your son, yes you can take the antibiotic, but only abscess is there otherwise this will not work, this will come around with the antibiotic, still you can do the salt water gargle, may give some relief in pain, take care and no need to worry about this
