Novacaine

The numbing agent typically used is called lidocaine. A small amount of epinephrine is added to allow the teeth to stay numb for the entire procedure. Not only do the teeth get numb but so does the surrounding soft tissues such as the lips and tongue. Most people comment that the affected area feels fat or big. Of course the tissues really don't change size.

The numbing sensation lasts three to five hours.

The area where the lidocaine was delivered can sometimes be tender and on occasion be slightly bruised.

Children can be very curious about the numb sensation. For a procedure where the lip was numbed they need to be very careful not to bite the lip. In our office the child and parent are always cautioned and shown not to bite their lip. We explain that while numb they cannot judge the pressure being applied.
