I need a professional opinion from you, if you would do me that favor.

My daughter had all 4 wisdom teeth extracted on 9-11. She was awake during
the entire procedure, with a local anesthetic given via injection.

As of today her tongue is still numb, although she is now feeling some
tingling in it, although slight.

The doctor performing the extraction told her not to worry as it can take up
to 5 weeks for the senses in her tongue to return to normal.

Is this true?

TIA! ;-)
