Hey, I've had a root canal treatment done this morning and my dentist gave me lots of LA as the tooth just wouldn't get numb for ages. I have a feeling that she gave me too much as its been 5 hours and the numbness won't go away! Its not even getting any less numb. The strange thing is that I can feel my teeth and my tongue, its just my cheek and lips that are numb.
Im very nervous about this as Ive had LA many times before and it never lasted this long! Does anyone know how long should the LA be in effect for and what are the possile causes of the numbness not going away?
