I had 2 or 3 shots of novacaine today for a root canal procedure. It took 6 hours before there was any noticable sign that it was wearing off! Totally gone by 8 hours.



I had to get 2 shots to get 2 teeth pulled and it started to get better after like 2 hours and gone within 3 to 3 and a half hours.
