Nitrous Gas Dentistry

Nitrous Gas Dentistry in Round Rock, TX!

Nitrous Oxide, also known as “laughing gas,” administered during a dental procedure helps relax patients who have a severe fear of needles and dentists, or have previously had traumatic experiences with a dentist. Nitrous is very useful for those who have difficulty getting numb, or those who cannot handle the sensory input like smells and noises present in a dentist’s office.

The dentist will administer the sedative gas through a mask that fits over your nose. As the patient breathes normally, the nitrous oxide, mixed with oxygen, helps you relax. Studies show that using nitrous oxide as a light sedative during dental procedures makes patients perceive less pain.

It is not intended to put you to sleep. Patients remain conscious throughout the procedure and retain the ability to respond to questions and directions from the dentist.

Safety & Effectiveness Of Nitrous Oxide

Studies have shown that Nitrous Oxide is safe and only has a temporary sedative effect on both children and adults. Dentists have been using nitrous oxide since 1844. It is the most tested and probably safest sedative in dentistry.

Most patients tolerate it well, and it is non-allergenic. The dentist can adjust the concentration for individual requirements. Patients remain conscious and maintain all natural reflexes when breathing the mixture of nitrous oxide and oxygen. The effects of the gas wear off within minutes of discontinuing the flow through the mask.

Experience Of Nitrous Oxide

Your dentist places a small nose mask on you and instructs you to breathe normally. You’ll feel the effect immediately upon inhaling, and your dentist will adjust the oxygen/nitrous mix until you are comfortable. Most people experience a sense of relaxation and a feeling that time has altered.

The effects of Nitrous Oxide wear off very quickly. Within minutes after the gas flow has stopped, people report feeling back to normal. Adult patients who have been administered nitrous oxide are capable of driving and returning to work after a brief observation period. Children can return to full activities after a brief observation as well.

Complicating Factors

Sinus congestion can limit the effectiveness of nitrous oxide because your ability to breathe through your nose is impaired. As always, tell your dentist about all medical conditions and medications you are taking.

Ask Your Dentist

Ask your dentist about using nitrous oxide during your procedure if you are tense, have dental phobias, have an easily triggered gag reflex, or are difficult to numb. The American Dental Association affirms that it is a safe and effective means of managing pain and anxiety in dentistry when used appropriately.

Stephanie Lara

Highly recommend this office in Round Rock. First and foremost, the facility is modern and extremely clean. The entire staff is friendly from the front desk to everyone in the back (including the manager). The woman who prepped me asked what music I preferred and quickly prepared me and put me at ease. She didn’t necessarily rush but she performed the X-rays gently and talked me through it all. I don’t have anxiety about the dentist but I always find it difficult to relax - that was not the case here. I was VERY pleased with Dr. H Nguyen. She is the first female dentist that I’ve encountered and it honestly made a difference. Dr. Nguyen was careful and thorough in her exam and patiently explained what she had found. The cleaning was so easy compared to other places. I definitely plan to continue coming here.


Awesome experience at Clearview Dental today! The front desk staff was friendly and accommodating. For my teeth cleaning, I got to work with Stephanie, she is very sweet and personable, and did a fantastic job. Afterward, I had the pleasure of speaking with Dr. Yoon which was great, he kindly took the time to address all my concerns and explained everything very well. Best dental experience I've had by far and looking forward to the next one. Easy 5/5

I had an amazing experience at Clearview Dental! The office is very clean and well-decorated. I was welcomed and assisted all way through my procedure by friendly staffs. Dr. Nguyen did my exam and cleaning, she explained thoroughly what treatments I need and gave candid advices regarding when each should be done. Plus, Dr. Nguyen and her assistant worked very gently on my teeth. Dr. Yoon is also friendly and personable. I’d definitely come back here in the future!
