Is Taking Ultracet Safe For The Treatment Of Toothache?

Hello. My 17 year old son is scheduled to have his wisdom teeth extracted in a couple of weeks. My employer has advised me to not allow my son to take any opioid for pain relief because he believes his daughter's drug addiction began when she had her wisdom teeth removed and took a narcotic pain medication. As far as I know, my son has not taken drugs, nor drank alcohol. But, he does come from a long genetic line of alcoholics / drug addicts (on both sides of his family tree). The oral surgeon has prescribed him Ultracet for after the operation. If taken as prescribed, is it considered safe? When I searched the internet for an answer, I found different point-of-views.
