"I'm really scared of my upcoming operation at the dentist. He doesn't want to put me to sleep and prescribed Ativan instead. Will that be enough?"

There is a possibility that the Ativan prescription may help in controlling anxiety and fear before the dental procedure. However, it may not be as effective as intravenous sedation. If the Ativan is not sufficient, it could be possible to reschedule the operation for a time when intravenous sedation can be administered. Consult with your dentist about your concerns and options available for sedation during the procedure.
