How Does Nitrous Oxide Work?

Nitrous oxide is used as a sedative in various healthcare capacities as it helps keep patients relaxed and calm. The patient is informed of the procedure and can choose the procedure after understanding how it works.

Nitrous oxide is a mild sedative that helps manage anxiety and pain during dental treatments. The gas is odorless, colorless, and inhaled through a mask placed on the patient’s nose. The patient is directed to breathe normally, and they start to feel its effect dawning on them within a few minutes.

What Does Nitrous Oxide Do?

Nitrous oxide is often a laughing gas, but it does not necessarily make you laugh. Instead, it works to slow down the nervous system, which makes you feel a bit disconnected.

You may feel slightly lightheaded or experience a tingly sensation or heaviness in your legs and arms. Nitrous oxide allows you to sit calmly throughout the medical procedure; you may even giggle once or twice.

How Does Nitrous Oxide Gas Work?

  • Nitrous oxide works to block the neurotransmitters in the body, which ceases anxiety from gripping you.
  • Nitrous oxide releases norepinephrine which ceases pain signals in the body.
  • Nitrous Oxide increases the stimulation of the pathway responsible for the release of dopamine, which enhances the feeling of euphoria.

Final Thoughts

Nitrous oxide has become important for many healthcare procedures and is considered a safe sedentary method. If you’re looking for a qualified kids’ dentist, contact Piedmont Pediatric Dentistry today to schedule an appointment.
