Laughing Gas

Nitrous oxide (laughing gas) is a safe, effective sedation option used to calm a child’s fear of a dental visit and enhance effective communication during a dental procedure. It also works well for children whose gag reflex interferes with dental treatment, cleanings or x-rays.

Your child remains fully awake and all natural reflexes remain in tact. They remain capable of responding to a question or request. 

The use of nitrous oxide during a dental appointment, can help your child get the dental care they need to protect their oral health.

Benefits of Nitrous Oxide for Kids

  • Has a rapid onset and is reversible
  • Can be adjusted to various concentrations
  • Provides some pain relief
  • Makes the time appear to pass more quickly
  • Eases anxiety associated with dental treatment
  • Helps to create a more positive dental experience

How Nitrous Oxide Works

Nitrous oxide is a blend of two gases: oxygen and nitrous oxide.

A small mask is placed over your child’s nose and, as they breathe normally, uptake occurs through the lungs.

Your child will smell a faint, sweet aroma and experience a sense of well-being and relaxation. Since it may produce a feeling of giddiness or euphoria, it is often called “laughing gas.”
