My two year old son has really dark red gums that are very swollen. When I tried to brush his teeth, they started gushing blood. They took forever to stop bleeding. There are no blisters or white spots but his gums are receeding from his front teeth. Last week is when it started and he had strep throat then. His fever was really high 104.3 but he has been on an antiobiotic since then and the problems with the gums started after he took the medicine. Should he go see a doctor or dentist and what could this be?
