... perscribed antibiotics to take, i took about 2 then i forgot, my crown is not put on and i found my antibiotics today and was worried of infectious diseases or even maybe a tumor. Im asking if its too late to take my antibiotics or not, i want to take them but it has been 4 months and my crown is now on, can i still take them? Would it help if i rubbed the antibiotic around the crown, and on my gums? Please i need answers
