Nitrous Oxide
When presented with something we didn’t want to do in the past, some of us may have said “I’d rather go to the dentist,” meaning dental care treatment was the only thing less desirable.
While the old adage remains mainly in the past, a reason why some may have been nervous about dental care treatment was the prospect of pain that came with it.
The current truth is that dental care is much more comfortable than it once was. At Oswego Dental Group, that includes the safe, effective use of nitrous oxide for analgesia (the lessening or absence of pain).
What Is Nitrous Oxide?
Also referred to as “laughing gas,” nitrous oxide is a colorless, faintly sweet-smelling, non-flammable compound used as a mild, short-acting sedative for certain dental procedures.
It provides sedation by slowing the nervous system to induce a sense of relaxed euphoria. In doing so, it helps to alleviate factors that might interfere with a relaxed dental procedure.
Nitrous Oxide Effects
Mixed with oxygen, nitrous oxide takes effect within minutes of administration and does not put the patient to sleep. The patient will often feel happy, calm and a bit light-headed. Some might also experience some tingling in the arms and legs or a feeling of being heavier in the chair.
Because nitrous oxide lessens pain sensitivity but does induce sleep, patients can still often hear and respond to the dentist’s instructions or questions.
Administering Nitrous Oxide
The American Dental Association points out that at least 12 delivery system audio and safety features have been developed to further enhance the safe and effective administration of the nitrous oxide and oxygen mix.
If you are scheduled for dental care treatment that might benefit from pain relief with nitrous oxide, your Oswego Dental Group dental hygienist will first discuss it with you and answer any question you might have.
If you would like nitrous oxide to be included with your dental care treatment, you’ll provide your consent to receive it.
When it’s time for the procedure, your dental hygienist will place a small plastic mask over the nose. (If a child will be receiving nitrous oxide for dental care treatment, a familiar scent might be added to help them get used to having the nose mask on.)
Next, the hygienist will open a tank valve to allow the nitrous oxide and oxygen to flow for you to breathe. The gas can be adjusted according to how you are feeling the desired effects.
Nitrous Oxide: During & After Procedure
The gas will continue to flow as your Oswego Dental Group dentist performs your procedure. Depending on the care you’re receiving, a local anesthetic might also be used, as nitrous oxide lowers but doesn’t eliminate pain.
Once your procedure is finished, the nitrous oxide will be turned off. You’ll be asked to breathe pure oxygen through the mask until you feel alert again. Nitrous oxide will often wear off almost as swiftly as it takes effect.
When you do feel alert, the mask will be removed. We’ll have you wait for a period to ensure the effects have sufficiently cleared for you to go home. In most cases, patients who receive nitrous oxide can drive themselves home after the waiting period.
You can typically return to normal activities after leaving your Oswego Dental Group appointment. You can eat and drink immediately after as well.
Patients who receive a local anesthetic in addition to nitrous oxide might prefer to wait a bit longer for the numbness to wear off before they eat and drink.
Some patients may also choose to start eating and drinking with something light and then work up to more-substantial food during the first several hours after the dental visit.
Nitrous Oxide: Whom Is It For?
Nitrous oxide can be a helpful component in dental care treatment for individuals who:
feel fearful or anxious about going to the dentist
have a sensitive gag reflex that can interfere with dental care
have very sensitive teeth
tend to respond less to local anesthesia
have difficulty controlling movements
have special needs (physical, cognitive or behavioral)
are younger in age and must undergo a longer dental procedure

Nitrous Oxide: Quick Facts
The gas was discovered in 1772 by the English chemist Joseph Priestley, an Enlightenment thinker and a contemporary of Benjamin Franklin.
During the 1770s, gases were often referred to as “airs.”
Priestley discovered the gas while living next to a brewery, which offered a nearly unlimited supply of carbon dioxide bubbling from the fermentation tanks. He used a pneumatic trough to isolate and identify eight gases, one of which would later be named nitrous oxide.
Another English chemist, Humphry Davy, who investigated gases as curative therapies, later wrote about nitrous oxide, including mention of its potential effects for pain management.
In the mid-1800s, American dentist Horace Wells began experimenting with nitrous oxide as a dental anesthetic.

- Julie C 03/12/2025What Our Patients Say
When my dentist of many years retired, I knew I would have to find another one to replace him. I had a “fear” of dentists, and I didn’t want to just randomly call another one. I searched online and read many, many reviews of other dentists, but I kept coming back to the Oswego Dental Group. The reviews were all five stars, and I thought to myself if even HALF the reviews are accurate, I’ll start there. But I wasn’t in a hurry…….who actually loves going to the dentist? I didn’t! Then I cracked a tooth a few weeks ago and knew I had to get it taken care of. I called Oswego Dental Group to set up an appointment on 2/25 and they fit me in on 2/26. From the moment I walked into the building until I left an hour and a half later, I realized the reviews I’d read were 100% spot on! I’m not familiar enough with everyone there to know all their names yet, but the dental assistant I had was absolutely wonderful in every possible way. Her sense of professionalism mixed with light hearted humor put me at ease immediately. Dr. MacDonald was the same ~ very professional, but with a good mix of humor, too. He checked out the tooth that I’d cracked and explained everything clearly to me. I walked out of there with a temporary crown on my tooth while a new one is being made. For someone who was once fearful of dentists, I have zero hesitation or concern of returning to Oswego Dental Group in a few weeks for the final crown to be put on my tooth. I was warmly greeted by staff members the moment I walked in the door, and felt the same sense of caring until the moment left. I would 100% recommend Oswego Dental Group to anyone ~ ESPECIALLY to anyone who has any hesitation about needing dental work!

We had a wonderful experience with Dr Milazzo and Ann. I called to ask for a consultation and got an appointment the next morning. Upon arriving we were greeted and shown to the back. My husband (70 yrs old) had a baby tooth that needed to be pulled but he is on blood thinners and has an LVAD (heart pump) and we always encounter people not wanting to help him because of his medical condition. But Dr Milazzo and his assistant Ann were like a breath of fresh air! They took great care of my husband and he got in there and pulled the tooth without a problem. It was amazing to be in a dentist office with such caring kind professional’s. We have found our dentist.
Thank you so much Anthony Milazzo and Ann for taking such great care of my husband.

- Gail KWhat Our Patients Say
Our family needed to find a new dentist since ours retired. We were going to him for over 35 years so picking a new office was a little nerve racking. From the very beginning the office made us feel very welcome. My children were very nervous at first but the moment the hygienists called their names the nerves faded since they were both very warm, friendly and caring. They were even comfortable enough to go by themselves.
I also had Amy for my appointment the next week and she was excellent. Also, Dr. Milazzo was great as well. I highly recommend Oswego Dental Group!

I spent a lot of time and a lot of money going to another dentist that just kept making everything worse…I was literally living on protien drinks because it hurt too much to chew. It took a little time (I needed a lot of work done) but Dr Milazzo fixed everything and I can finally eat again. I’m forever grateful for Oswego Dental Group and would without hesitation recommend them.
