Nitrous Oxide is a sweet-smelling, non-irritating, colorless gas that you can inhale. It has been the primary means of sedation in dentistry for many years and is known for its safety. When administered, the patient receives 50–70% oxygen with no less than 30% nitrous oxide.

​

• Safety and Control: Patients are able to breathe on their own and maintain control of all bodily functions. They might experience mild amnesia and may even fall asleep, often not remembering the details of their appointment.

 

Advantages of Using Nitrous Oxide

​

• Adjustable Sedation: The depth of sedation can be easily adjusted at any time to increase or decrease its effects.

• No After Effects: Patients do not experience aftereffects such as a "hangover."

• Cardiopulmonary Safety: Inhalation sedation is safe and does not adversely affect the heart or lungs.

• Reduces Gag Reflex: It is highly effective in minimizing gagging.

• Rapid Onset: It works quickly, reaching the brain within 20 seconds. In as little as 2–3 minutes, its relaxation and pain-relieving properties begin to take effect.

 

Reasons to Avoid Nitrous Oxide

​

• Medical Conditions: Patients diagnosed with chronic obstructive pulmonary disease (COPD) should avoid using nitrous oxide. Additionally, those with emphysema, exotic chest problems, multiple sclerosis (M.S.), a cold, or other breathing difficulties may want to avoid its use.

• Trial Use: It is advisable to ask your dentist for a "5-minute trial" to see how you feel with this type of sedation method before proceeding with a full treatment.

 

For a safe and comfortable dental experience, nitrous oxide sedation can be a valuable option for many patients. However, it’s important to consider your medical history and consult with your dentist to ensure it’s the right choice for you.
