There are a lot of reasons why nitrous oxide, or “laughing gas,” is a popular option in sedation dentistry. One reason it is preferred over other options is that, while it is effective for relieving anxiety and reducing the perception of pain, its effects are known to clear quickly when compared with other medications.

Even so, you may be concerned about getting home after your dental procedure. Is it safe for you to get behind the wheel, or should you arrange for other transportation?

What is Laughing Gas, and How Does it Work?

Nitrous oxide is a safe and commonly used form of sedation in dental care. It is typically recommended for patients who experience dental anxiety or discomfort during procedures. Administered through a small mask placed over the nose, nitrous oxide is mixed with oxygen and breathed in.

The gas begins to take effect almost immediately, helping you feel calm, comfortable, and sometimes even a little euphoric.

Nitrous oxide works by affecting the central nervous system. It slows reaction times and dulls sensory perception, reducing pain and anxiety. However, unlike deeper forms of sedation, it keeps you awake and responsive, making it a great option for minimally invasive dental treatments.

The effects of laughing gas typically wear off quickly after the flow of the gas is stopped, making it a safe and convenient choice for most patients.

The Immediate Effects of Laughing Gas

Laughing gas is known for its mild and temporary effects. Here’s how you can expect to feel:

• Calm and Relaxed: Nitrous oxide alleviates feelings of fear or nervousness, which is particularly helpful for patients with dental anxiety.
• Tingling or Floating Sensations: Many patients describe a light, floaty feeling or a tingling sensation, especially in their hands and feet.
• Mild Euphoria or Laughter: While not everyone feels giddy or laugh-out-loud funny, laughing gas often promotes a general sense of happiness and well-being.
• Reduced Perception of Pain: Laughing gas dulls pain sensitivity, making procedures more comfortable without the need for deep sedation.
• Mild Drowsiness: You remain awake and alert but might feel slightly groggy, making it easier to relax in the dental chair.

While these effects are mild and temporary, they still have implications for activities such as driving, which require you to be alert and coordinated.

Is it Safe to Drive After Laughing Gas?

The short answer is yes, for most people, it is safe to drive after receiving laughing gas. Just like how they come on, the effects of nitrous oxide wear off quickly, typically within 5 to 10 minutes after the mask is removed.

Most patients recover fully within this time frame and feel capable of resuming normal activities. However, since the effects can vary slightly from person to person, so if you still feel them after 10 minutes, let your dentist know and wait until you feel that they are completely worn off before attempting to drive.

Tips for a Safe and Stress-Free Experience

If you’re planning for a procedure that involves laughing gas, here are some tips to ensure both your safety and peace of mind.

Arrange Transportation Just in Case

Even though most patients can drive themselves home after receiving laughing gas, it’s better to err on the side of caution, especially if it’s your first time. Have a friend or family member drive you if you are concerned.
