Application Process

An applicant must hold an active dental hygiene license or dental assistant registration prior to submitting an application for the nitrous oxide monitoring endorsement. Please do not contact the Licensing Division to check the status of your application unless it has been longer than four (4) weeks and you have not been contacted. Applications are processed in the order received. If you mailed in your application and fee, your payment will be processed before your application is reviewed. The estimated processing turnaround time is 3-4 weeks. Applicants with a criminal history or disciplinary action may expect a longer processing time.

Once the application has been approved, an approval letter will be sent confirming the endorsement on your license. At that time, you may then visit the “Print E-Certificate” option to print an updated renewal. The Nitrous Oxide Monitoring approval will be located on the bottom left side of the renewal.
