Nitrous Oxide

Nitrous oxide (or laughing gas) can help reduce pain and anxiety during dental treatment. 

How Does Nitrous Oxide Work?

Nitrous oxide (also known as laughing gas) is colourless and virtually odourless, and is administered to your child through a nasal hood along with oxygen. The drug acts on the central nervous system causing euphoria with little effect on your child’s breathing. Laughing gas is a mild sedative, which means your child will be awake and will still need to cooperate for the dental treatment. 
Laughing gas is absorbed quickly in the lungs, allowing for rapid onset and recovery (typically within two to three minutes). This also means that your child will not leave the office feeling “drugged”. It does not significantly impair reflexes, and most importantly, protects your child’s cough reflex. Generally, laughing gas is quite safe when administered by a qualified pediatric dentist.

Important Considerations

Keep in mind, laughing gas does not replace the need for local anesthesia or dental freezing. It is imperative that your child avoid eating (particularly heavy foods such as dairy, grease or eggs) two to three hours prior to administering the laughing gas. In rare instances, it can incite stomach upset.
Dr. Perusini and the staff at Avenue Pediatric Dentistry look forward to answering your questions regarding sedation. As always, your child’s safety is our priority, and we look forward to working together to achieve the best outcome for your child.
