Understanding Sedation Dentistry

Visiting the family dentist can be a nerve-wracking experience for some individuals, especially when it comes to specific dental procedures. Thanks to advancements in sedation dentistry, there are now options available to help ease anxiety and discomfort during these visits. One of the most common and effective forms of sedation is the use of laughing gas. 

In this article, we will explore how laughing gas works, its benefits, and what to expect when using it at your next dental appointment.

What is Laughing Gas

Laughing Gas: A Brief Overview

Laughing gas, scientifically known as nitrous oxide (N2O), is a colorless and odorless gas that has been used in dentistry for over a century. It is administered through a small mask that fits over the nose, allowing patients to breathe it in along with oxygen. The gas works quickly to induce a sense of relaxation and comfort, making it an ideal sedative option for dental procedures.

How Laughing Gas Works

When inhaled, laughing gas works by slowing down the body’s response to pain and anxiety. It does this by targeting the central nervous system, specifically the brain and spinal cord. Nitrous oxide triggers the release of endorphins and dopamine, which are natural “feel-good” chemicals that help to calm nerves and create a sense of euphoria. This results in patients feeling more at ease and less anxious during their dental appointment.

It is important to note that laughing gas does not put patients to sleep or make them unconscious. Instead, it places them in a state of conscious sedation, where they remain awake and aware of their surroundings but feel more relaxed and comfortable throughout the procedure.

Benefits of Laughing Gas in Dentistry

Advantages of Using Laughing Gas

There are several benefits to using laughing gas in dental procedures, making it a popular choice for both patients and dentists alike. Some of these advantages include:

  1. Fast-Acting: Laughing gas takes effect within minutes, making it an efficient option for sedation dentistry. It also wears off quickly, allowing patients to return to their daily activities soon after their appointment.
  2. Adjustable Levels: The concentration of laughing gas can be easily adjusted by the dentist, allowing for personalized levels of sedation based on individual patient needs and preferences.
  3. Minimal Side Effects: Compared to other forms of sedation, laughing gas has very few side effects and is considered safe for most patients. Some patients may experience mild dizziness, nausea, or headaches, but these symptoms typically subside shortly after the gas is stopped.
  4. Non-Invasive: Unlike oral or intravenous sedatives, laughing gas does not require needles or pills, making it a more appealing option for those with a fear of needles or difficulty swallowing medication.
  5. Effective for Various Procedures: Laughing gas can be used for a wide range of dental procedures, from routine cleanings to more invasive treatments, making it a versatile and convenient option for both patients and dentists.

What to Expect When Using Laughing Gas

The Laughing Gas Experience

If you are considering using laughing gas during your next dental appointment, here is what you can expect:

  1. Prior to the procedure, your dentist will place a small mask over your nose, through which the laughing gas will be administered.
  2. You will begin to feel the effects of the gas within minutes. You may experience a sense of warmth, tingling, or mild euphoria.
  3. Throughout the procedure, you will remain awake and able to communicate with your dentist. However, you will likely feel more relaxed and less concerned about any discomfort or anxiety.
  4. Once the dental procedure is complete, your dentist will gradually reduce the concentration of laughing gas and replace it with pure oxygen. This helps to clear the nitrous oxide from your system and prevent any lingering side effects.


Laughing gas is a safe and effective sedative option for those who experience anxiety or discomfort during dental procedures. With its minimal side effects and adjustable levels, laughing gas is a popular choice for patients of all ages and can be used for various dental procedures.
