Why is nitrous oxide not routinely used in dental clinics?

I do not use: I am in practice for 37 years and have never used nitrous oxide. That does not mean it is not necessary. It is used mainly to manage anxiety. Good luck

Number of reasons: Many reasons; here are a few. Cost, risk factor, certification needed by practitioners to use it, facility space limitations, potential for misuse, increased difficulty to work when it is being used and is often in the way, extra time required to use and re-oxygenate the patient. Additionally, it has ,sadly, become a crutch for many, although an almost bona fide necessity for some. Good Luck.
