What is Laughing Gas?

Laughing gas can be used for a range of dental procedures, from teeth cleanings to fillings. However, some procedures will still require local anesthesia in addition to the gas to appropriately manage pain. If your child has a history of dental anxiety, laughing gas sedation may be used to help your child relax while receiving dental care.

Common reactions to laughing gas include feelings of happiness, mild euphoria, light-headedness, and relaxation. It’s perfectly normal for your child to giggle or act excited, though most just feel more at ease.


Benefits of laughing gas:

  • Wears off quickly
  • Patient is awake and aware
  • No lingering side effects
  • Reduces dental anxiety
  • Helps your child remain still during routine or restorative dental procedures

Wears Off Quickly

We administer laughing gas via a mask we place over your child’s nose. While this form of sedation works quickly to put your child at ease, the calming effects of laughing gas wear off almost immediately after we remove the mask. Unlike other types of sedation dentistry, your child can return to school or other activities after their appointment unless our dentist advises otherwise.


Patient is Awake and Aware

Laughing gas is different from sleep dentistry because your child will be awake and responsive during their procedure. This means that your child will be able to actively cooperate if our dentist needs your child to open their mouth wider or tilt their head to access a tooth.


No Lingering Side Effects

There are no lingering side effects of laughing gas, which makes it perfectly safe for children. In fact, adults who are given laughing gas can drive themselves home or return to work. Other types of sedation dentistry (like pill sedation) require you keep your child home from school and monitor them for the rest of the day for adverse side effects. With laughing gas, you don’t have to worry about side effects.
