Laughing gas, also known as nitrous oxide, is a chemical compound widely used in medicine to numb patients during painful procedures, including dental treatments.
Many of us have undergone medical procedures where this gas was used, but how many of us have asked, “Is laughing gas safe?” This blog provides all the information you need to know about this gas so that you can feel confident about your health.

Is Nitrous Oxide Good or Bad for You?
Laughing gas is not harmful to your health as long as it is administered by a professional and in moderate amounts, ensuring no risk. However, if used negligently and without proper knowledge, the use of this gas can have fatal consequences for your health.
What Does Laughing Gas Do?
Nitrous oxide is a colorless gas widely used for sedation and pain relief. Due to its anesthetic properties, it has been extensively employed in dentistry as an adjunct in sedation and anesthesia maintenance.
Laughing gas, or nitrous oxide, is commonly used in medical and dental procedures to provide mild sedation and pain relief. When inhaled, it induces a sensation of euphoria and relaxation, reduces anxiety, and can help dull pain. It works by slowing the body’s reaction time and altering pain perception in the brain.
How Long Does Laughing Gas Last?
The effects of laughing gas generally begin within a few minutes of inhalation and can last throughout the procedure. Once the gas supply is stopped, its effects quickly dissipate, usually within a few minutes. Patients typically recover fully within 5 to 10 minutes, allowing them to leave the medical facility shortly after the procedure.
Use of Laughing Gas
Laughing gas is administered through a mask placed over the nose. The patient inhales the gas mixed with oxygen, which quickly induces a feeling of relaxation and euphoria. It is primarily used during medical and dental procedures to alleviate pain and anxiety. The amount of gas administered is carefully adjusted by the healthcare professional to ensure adequate sedation without loss of consciousness.
Once the procedure is complete, the gas supply is stopped, and the patient inhales pure oxygen for a few minutes to eliminate any remaining nitrous oxide from the body, facilitating a quick and safe recovery.
Individuals Who Shouldn’t Use Nitrous Oxide Sedation
While laughing gas is generally safe when administered by a healthcare professional, certain groups of people may be more affected by its use. Here are some of them:
- Severe Respiratory Conditions: Individuals with chronic respiratory issues, such as Chronic Obstructive Pulmonary Disease (COPD), may have difficulty inhaling the gas.
- Vitamin B12 Deficiency: Nitrous oxide can interfere with vitamin B12 absorption, so those with a deficiency should avoid its use.
- Severe Psychiatric Disorders: People with certain mental health disorders may experience adverse effects.
- Pregnancy: Especially in the first trimester, its use should be avoided as it could affect fetal development.
- Middle Ear Problems: Nitrous oxide sedation can increase ear pressure, which could be problematic for those with middle ear infections or balance issues.
- History of Substance Abuse: Individuals with a history of substance abuse may be more susceptible to the euphoric effects of the gas, posing a risk.
Risks of Using Laughing Gas
As long as nitrous oxide is administered by a healthcare professional, there are no significant risks, only effects like euphoria, a sense of well-being, and laughter. However, non-medical use can have severe consequences such as asphyxiation, hallucinations, uncontrolled vocalization, altered perception, spatial and temporal disorientation, or reduced pain sensitivity.
Possible Complications of Nitrous Oxide in Dental or Medical Settings
Having a good healthcare professional monitoring you during nitrous oxide administration and assessing any potential risks based on individual health conditions is essential. Since each patient is different with distinct conditions, some complications that may arise include:
- Respiratory Difficulties: Although rare, nitrous oxide can cause respiratory issues, especially in individuals with preexisting respiratory conditions or compromised lung function.
- Nausea and Vomiting: Some patients may experience nausea or vomiting as a side effect, especially if administered in high doses or if the patient has a sensitive stomach.
- Headaches: The use of nitrous oxide can sometimes cause headaches, which may occur during or after the procedure.
- Dizziness and Fainting: Patients may feel dizzy or lightheaded during the procedure, which is generally temporary but can be uncomfortable.
- Euphoria or Disorientation: While often a desired effect, excessive euphoria or disorientation can be problematic, especially if it affects the patient’s ability to follow instructions or cooperate during the procedure.
- Allergic Reactions: Although rare, some people may have allergic reactions to nitrous oxide, such as skin rashes or breathing difficulties.
Understanding these factors can help ensure that the use of nitrous oxide is safe and effective for your medical or dental needs.
