If my child is getting dental work with laughing gas and still doesn't cooperate what will they do?

Likely reschedule: Dental work or restoration is often done under anesthesia/deep sedation if the child is not old enough to remain settled through the procedure.

Nitrous Tx Options: Options available for treatment to be completed: 1. Iv sedation 2. Conscious sedation 3. Hospital dentistry.

Probably refer: The next step would pediatric sedation or possibly do the procedure in the operating room under very deep sedation with an anesthesiologist.

General anesthesia: If n2o isn't enough, the dentist may suggest a general anesthetic.
