I Just Went In To The Dentist A Couple Days

I just went in to the dentist a couple days ago and he said my crown was infected due to a root canal done wrong and I was prescribed amoxi clav and naproxen now it's been 2 days and I have been taking them as prescribed but noticed the other day my gums were swollen now tonight it is swollen so bad it burst in my mouth can and I'm having shortness of breath can I die?
