Suggest Medicines For Decayed Tooth

My husband had a severely decayed tooth pulled on Friday (5 days ago) and dentist did not prescribe any antibiotics. He had a fever (he wouldn't let me take his temperature) but his skin was incredibly hot to touch and he was sweating profusely. Fever comes and goes but he has spiked one multiple times per day through last night (I am at work so do not know how his day has gone). He has also been complaining of chills, headache, fatigue, cough, and nasal congestion (he already had influenza A in January of this year). Want to know if I should ask dentist to prescribe him something and should I specify what antibiotic?
