N2O Sedation

Nitrous oxide, commonly known as "laughing gas," is a odorless gas that helps patients relax and reduce pain during dental procedures. It is administered by our skilled staff through a mask, mixed with oxygen, and inhaled to create a calming effect.

Nitrous oxide slows down the body’s response to stimuli, reducing anxiety and discomfort while keeping you conscious and able to communicate. It provides a mild euphoria and sometimes a floating or tingling sensation to provide comfort during your endodontic procedure.

• Reduces anxiety and fear for nervous patients.
• Minimizes discomfort and enhances pain management.
• Fast onset and recovery – effects wear off quickly after stopping the gas.
• Allows patients to remain awake and responsive during the procedure.

The effects typically begin within a few minutes of inhalation.

Once the gas is turned off, the effects wear off within 5–10 minutes as you breathe pure oxygen. Most of our endodontic patients feel normal right away.

Yes, since the effects wear off quickly, most patients can safely drive home after their appointment. However, your Empire endodontic team will confirm if you are fully alert before you leave.

Nitrous oxide may not be recommended for patients who:

• Are pregnant (especially in the first trimester)
• Have respiratory conditions such as COPD
• Have a history of substance abuse
• Have a severe phobia of masks or difficulty breathing through the nose

• Avoid eating a large meal before the procedure to minimize nausea.
• Wear comfortable clothing to help you relax.
• Inform your dentist of any medical conditions or medications you’re taking.
