Nitrous Oxide

Nitrous oxide, also known as laughing gas, is the most commonly used form of sedation in dentistry. It is a colorless, slightly sweet gas that is used during dental treatment for relaxation and anxiety relief. When inhaled, it can induce feelings of euphoria and sedation as well as drowsiness, warmth and tingling in the hands, feet and/or mouth. In the dental setting, it will not induce unconsciousness. You will be able to talk and swallow as needed. The levels of gas can be adjusted until you feel comfortable and relaxed.

Nitrous oxide sedation is very safe and effective and can be used on children and adults alike. Once the procedure is over, you will be given 100% oxygen for 5-10 minutes in order to flush the nitrous out. The effects wear off fairly quickly and you will be able to drive yourself home and return to your daily activities.

Preoperative guidelines: Nitrous oxide is administered through a nasal mask. You must be able to breathe through your nose. Let us know if you have blocked nasal passages or a cold. On the day of your appointment, do not take any antidepressants/sedatives unless your dentist is aware of them.

Postoperative guidelines : Recovery from nitrous oxide sedation is rapid. The gas will be flushed from your system with 100% oxygen for 5 to 10 minutes. If you feel dizzy after the sedation, remain seated and the sensation should pass in a few minutes. Do not leave the office until your head feels clear and you are able to function (i.e. walk and drive) safely.

Review Us

We love to hear what our patients think!

Dr. Cheng and her staff are fabulous! I have seen her several times for multiple fillings and a partial crown, and each time they have gone out of their way to ensure my comfort and to make me feel calm and relaxed. They are friendly, yet always professional- I feel confident trusting my chompers to them. El Campo is lucky to have a dentist like Dr. Cheng!

Dr Cheng is always friendly and thorough when it comes to your dental care. In the years that my family have been a patients at this office we have always been treated respectfully and in a timely manner. The staff is always friendly and there to help when needed. TF

I am usually scared to go to the dentist. Dr Chang was sooo very kind and gentle.

This group of ladies are always so kind! Janet and Angie at the front desk are the first women you see, and they are always so pleasant! Sarah is my hygienist and she’s so sweet and great at what she does! Love Dr. Cheng! She is so soft spoken and amazing at what she does. I didn’t go to the dentist for 8+ years and my mouth was full of cavities before I saw Dr. Cheng, and she fixed me right up and never made me feel judged. She also removed my wisdom teeth and I recovered within a couple days! I highly recommend these ladies!! ❤️❤️❤️

I had a tooth cleaning done today & have been very pleased with my dental hygienist. I have been going to El Campo Dental Clinic since 1979. The employees there are of the highest rated. Thanks to Dr John, Dr Cheng and their staff.
