If dental visits make you nervous, nitrous oxide—often called laughing gas—can help you relax while staying fully conscious and in control.
This safe and gentle sedation method is inhaled through a small mask, providing a calm, comfortable experience within minutes. The effects wear off quickly, allowing you to drive yourself home and continue your day as normal. With its long history of safety and effectiveness, nitrous oxide is an excellent option for patients who want a more relaxed, stress-free dental visit.
Laughing Gas & Comfortable Sedation
Nitrous oxide is a sweet-smelling, non-irritating, colorless gas that you can breathe.
Nitrous oxide has been the primary means of sedation in dentistry for many years. Nitrous oxide is safe; the patient receives 50-70% oxygen with no less than 30% nitrous oxide.
The patient is able to breathe on their own and remain in control of all bodily functions.
The patient may experience mild amnesia and may fall asleep, not remembering all of what happened during their appointment.
There Are Many Advantages To Using Nitrous Oxide & Inhalation Sedation
- The depth of sedation can be altered at any time to increase or decrease sedation.
- There is no aftereffect, such as a “hangover.”
- Inhalation sedation is safe with no side effects on your heart and lungs, etc.
- Inhalation sedation is very effective in minimizing gagging.
- It works rapidly as it reaches the brain within 20 seconds. In as little as 2-3 minutes, its relaxation and discomfort-reducing properties develop.
Reasons To Not Use Nitrous Oxide & Health Considerations
You should not utilize nitrous oxide if you have been diagnosed with chronic obstructive pulmonary disease (COPD). Though there are no other major contraindications to using nitrous oxide, you may not want to use it if you have emphysema, chest problems, M.S., a cold, or other difficulties with breathing.
You may want to ask your dentist for a “5-minute trial” to see how you feel with this type of sedation method before proceeding.
How We Administer Nitrous Oxide & What To Expect
At Portsmouth Dental Associates, we prioritize your peace of mind and strive to make every appointment as relaxing as possible. Before starting any treatment, our experienced team fits a soft, comfortable nose hood over your nose. You will simply breathe normally through your nose, inhaling a controlled mixture of nitrous oxide and pure oxygen. Within minutes, you will feel a soothing sense of warmth, lightheadedness, and deep relaxation throughout your body for your visit in Portsmouth, RI.
Monitoring & Rapid Recovery Process
Throughout your entire procedure, our team constantly monitors your comfort levels and vital signs. Because nitrous oxide acts rapidly, we can adjust the gas concentration instantaneously if you need deeper relaxation or wish to lighten the effect. Once your dental work is complete, we flush your system with pure oxygen for several minutes. This completely clears the nitrous oxide from your lungs and bloodstream, restoring full alertness so you can leave our office safely without needing a designated driver.

Inhalation sedation is a versatile option suitable for a wide range of patients undergoing both routine check-ups and complex restorative treatments.
