Normally, how long would the numbness after cavities go away?

1 to 6 hours: It all depends on the type of anesthetic used by your dentist.

Usually in 2-4 hours: Modern anesthetic is very effective. Depending on the type used, numbness will last between 2 and 4 hours. Some types will last as long as 8 hours (marcaine).
