Nitrous Oxide/Sedation Dentistry (Laughing Gas)

To ensure visits to our office are comfortable and as stress-free as possible, procedures with nitrous oxide sedation (sedation dentistry) are available.
In sedation dentistry, nitrous oxide, “laughing gas” is mixed with oxygen and inhaled through a small mask placed over the patient’s nose. The dentist is able to control the amount of sedation received, and the gas has the benefit of wearing off quickly.
The patient is not fully “put to sleep,” but is sedated enough to maintain increased comfort and calmness during the procedure. Nitrous oxide is considered a very safe and effective sedative and may be an option you wish to discuss with the dentist to ease your or your child’s dental experience.
Note that nitrous oxide sedation is not exclusively used for children. Adults who may be experiencing dental anxiety may benefit from utilizing nitrous oxide sedation for lengthy procedures.


Commonly Asked Questions about Sedation Dentistry and Laughing Gas for Kids
Is Nitrous Oxide Safe for Children?
Yes, it is! In fact, our dentists typically prefer to administer nitrous oxide to children compared to other deeper levels of sedation. This is because it has an excellent safety profile.
Why Are Patients Given Oxygen After Nitrous Oxide?
It is common to administer 100% oxygen to patients once they are no longer breathing in nitrous oxide. The oxygen therapy eliminates any lingering nitrous oxide in the lungs, while helping patients become more alert. The oxygen therapy also prevents headaches, which can sometimes be caused by nitrous oxide.
Who Shouldn’t Receive Nitrous Oxide?
Although nitrous oxide is safe for most people, we are always sure to review your health history before proceeding with treatment under nitrous oxide. Typically, nitrous oxide is not recommended for women in their first trimester of pregnancy. Also, the use of nitrous oxide is generally contraindicated for patients who may have: COPD, methylenetetrahydrofolate reductase deficiency, cobalamin deficiency, or a history of substance abuse.
Should I Eat Before Receiving Nitrous Oxide?
If you know that you are going to be receiving nitrous oxide, you can feel free to have a light meal a few hours before treatment. However, some patients find they will become nauseous as a result of the nitrous oxide. In these cases, we advise to avoid eating too much food before treatment, so you don’t become sick. If you or your child has never had nitrous oxide before, refrain from eating prior to treatment until you know if it will make you feel nauseous.

⭐⭐⭐⭐⭐ “I had a difficult time getting my kids to a dentist. I tried many different dentists from Haverhill, Methuen, Lawrence, and Andover. My kids like their dentist now and make an effort in dental care. Great team, friendly, and understanding. It’s truly a relief to have found a great dentist.” – Karla B.
⭐⭐⭐⭐⭐ “I took my 4 year old daughter and two year old son to this clinic. My daughter had a very bad experience before, so she could not stop crying at the minute she was in the clinic. But the dentist was really great with my kids! Took it slow and made it fun for my kids! Dr. Bui was so patient, warm, and professional!” -Lily B.
