Nitrous Oxide

The colorless gas known as nitrous oxide or “laughing gas” is commonly used in full-body sedation during dental procedures and other surgeries. As a dissociative drug, nitrous oxide causes a feeling of detachment or “high” that can cause patients to feel a little detached and “loopy.” However, the process is painless and temporary.

Nitrous oxide is used when surgical procedures require the patient to be motionless. This aids the dentist in performing the procedure efficiently and makes the patient more comfortable as well.

The symptoms of nitrous oxide include:

• Laughter
• Numbness
• Euphoria
• Sedation
• Blurred vision
• Dizziness
• Tiredness

These symptoms are completely normal reactions to nitrous oxide and are temporary. Despite this, notify your doctor about your pre-existing health conditions as those with heart disease, epilepsy, or other conditions may be excluded from using nitrous oxide.

The effects of nitrous oxide last for only a few minutes after taking the mask off. Some patients report needing to “come down” from the high for as long as 15 minutes. In this case, we advise you to remain in the office where you can be monitored until you feel safe enough to drive.

There’s a common misconception online that nitrous oxide causes memory loss, permanent numbness, weakened immunity, and other serious symptoms. These symptoms are possible for those who use nitrous oxide regularly as a recreational drug. In the amount administered by your dental professional, nitrous oxide will not cause any permanent symptoms in the absence of pre-existing conditions.
