If you have not been maintaining your oral health due to anxiety about the dentist, you're a good fit for nitrous oxide sedation at Ah! Dentistry. Our three facilities in the DFW area provide nitrous oxide sedation for complex dental procedures and to comfort individuals with dental fears and anxieties during normal checkups and exams. Nitrous oxide (N2O) gas is a simple sedation option that may help you relax safely during your visit. Also called laughing gas, nitrous oxide sedation is offered by our experienced dental team to keep you awake while being completely relaxed. Set up a consultation for more information on the use of sedation methods, like N2O, during your dental visits.

Best Candidates

N2O is an incredibly popular sedation technique that can be utilized with little risk on adults and children. Prior to recommending the use of nitrous oxide, we will assess your concerns, current medications, and medical history to be sure that nitrous oxide gas is indeed a fit for you. Nitrous oxide sedation can be utilized for advanced or routine procedures paired with a local anesthesia to help decrease potential pain. Nitrous oxide sedation can also be used to ease fear or anxieties toward dental work that prevents you from keeping your regular dental appointments. Nitrous oxide gas may not be a good choice if you have extreme phobias, trouble breathing through your nose, COPD, or other similar health concerns.

What To Expect

Before the procedure is initiated, the N2O will be administered to you via a mask. As you take in the gas, it will act quickly and begin taking effect. A member of our dental team will observe your response to the gas, as well as your vitals, and adjust the amount as required during the appointment so you stay at ease. You should expect a tingling sensation in your outer extremities, and a feeling of well-being, warmth, and euphoria as the N2O begins to take effect. Nitrous oxide is usually used in conjunction with a local anesthetic, like lidocaine, to deaden sensation. When the procedure is done, the gas is shut off and the effects being to fade immediately.


Recovery from nitrous oxide sedation is typically immediate because the medication is eliminated from the body in just a few minutes. You will be ready to operate a vehicle and return to your daily activities as soon as you leave our facility. Side effects are not common, but you might experience sweating, nausea, vomiting, fatigue, headaches, or chills. Do not hesitate to call our team if you have any side effects that last longer than a few days. To decrease the chance of nausea, it is recommended that you consume a small meal or light snack prior to your appointment and then hold off about three hours after your appointment before eating a heavy meal.

Insurance Coverage

If you carry dental insurance, we will make contact with your carrier to obtain your existing coverage as it pertains to nitrous oxide sedation. This information will help us determine your expected costs prior to your procedure. For those who do not carry dental insurance, Ah! Dentistry takes several types of payment, which includes medical financing to help make your procedure more affordable.
