i have to get a crown next week (which sucks beyond belief) and with the research i found online it states that novocaine will get out of your system within 2-3 hours, or when you dont feel the novocaine anymore in your mouth. i also found that it doesnt travel through the blood, but stays local at the injection site- is this true info or should i be really concerned? my pedi said one to 2 hours, but the dentist said to dump and pump for a whole day! i am not sure what to believe, any help would be great!
*also, i have seen that something called lidocaine is considered safer- is this something i could request the dentist to use?
