Happy Gas


The use of Happy Gas or nitrous oxide (N2O) is an effective local sedation method. It’s a preferred method because the effects manifest fast and they’re reversible. Possible side effects might only be related to improper administration.


It’s very helpful especially during discomforting dental procedures. Many patients become anxious about the possible pain that the procedure will bring. Good news is the nitrous oxide can help patients feel more comfortable.

The Maintenance Visit

It’s a mild sedation method which is why you can still hear your dentist and respond accordingly. After the procedure and some rest, the effects will wear off and you’ll be ready to go home on your own.


In fact, the use of Happy Gas is preferred especially when a child is on the dental chair. The nervousness and anxiety will dissipate during a potentially discomforting dental procedure. To successfully accomplish this, the dentist will meticulously control the administration of nitrous oxide.

Possible side effects to watch out for

Although most side effects are just a result of improper administration, it’s still worthwhile to pay attention to them.


  • Headaches
  • Excessive sweating
  • Nausea, vomiting and shivering
  • Fatigue


It’s important to tell your dentist if you’re experiencing any of these after the procedure. It might not be safe to drive home or do other things after the treatment.


In most cases still, proper administration of nitrous oxide can lead to the successful completion of a dental procedure. Patients will be less anxious and the overall process will become smoother.

When not to use nitrous oxide

Happy Gas may not still be appropriate for everyone. For instance, this sedation method may not be appropriate for women in their first trimester of pregnancy. It’s the same case when the person has a chronic obstructive pulmonary disease or a cobalamin deficiency.


There are other deciding factors. It’s important to talk with your dentist first so you can certainly know if the use of nitrous oxide is appropriate or will be effective for you.
