I Had Methemoglibinanemia From Azo Standard. Im Now Using Benzo-jel

i had methemoglibinanemia from azo standard. im now using benzo-jel for some teeth i had pulled. its was intensive because 3 broke into pieces. can benzo-jel cause the problem i had with the azo? if so, how much is too much. im kinda scared of it, but im in terrible pain. one became a dry socket . i got no stiches and am wearing a temp. partial till i heal. but the partial is causing sores cause i dont think it fits. the dentist said i have to wear it like this cause it is too thin to adjust. its been a month and the very back ones havent even started to heal. they fill up with food. sorry, no credit card, thought it was free
