Laughing Gas In Dentistry: What Is It? – Your Dentist Near Me In Lincoln, NE Explains

Nitrous oxide is a gas that is not only colorless but also odorless. As you might know, Nitrous Oxide is also commonly referred to as “laughing gas”. When nitrous gas is inhaled, it slows down reaction time. Thus, the feeling of nitrous gas results in a euphoric, calm feeling.
Nitrous oxide can be used to treat discomfort and pain. In addition, nitrous gas can also function as a mild sedative. Because of this property, nitrous gas can sometimes be used for dental procedures to help reduce anxiety and promote relaxation.
Nitrous oxide, or laughing gas, is also very effective as a sedative. However, the good news is that it doesn’t take long for the effects of nitrous gas to wear off, thus making it very safe. However, keep in mind that there are possible side effects, just like any other drug type.
Here we’ll answer the following commonly asked questions about nitrous oxide in dentistry:
Why do some dentists not use laughing gas?
Do I need laughing gas for a root canal?
Can I ask for laughing gas at the dentist?
Does laughing gas work?
First Thing To Know…
Potential Short-Term Side Effects Associated with The Use Of Laughing Gas In Dentistry
What Are They?

Although there are possible side effects from nitrous oxide inhalation, those who receive laughing gas often don’t have any complications or adverse reactions whatsoever.
When side effects do occur, they often result from inhaling the gas too quickly or result from the inhalation of too much gas.
What are some common short-term side effects? Common short-term effects include:
- dizziness
- excessive sweating
- fatigue
- nausea
- vomiting
- Shivering
On occasion, some people will also experience sound distortion or hallucinations after inhaling nitrous oxide or laughing gas. When receiving laughing gas, oxygen is frequently administered. Suppose your provider chooses not to administer oxygen along with the nitrous gas. In that case, you will likely receive oxygen for about three to five minutes after your dentist in Lincoln, NE, turns off the laughing gas.
Why do you need oxygen? Oxygen will aid in clearing any remaining nitrous gas from within your body. The use of oxygen will also help you regain alertness after completing your procedure. Getting sufficient oxygen can also help prevent headaches, another possible side effect associated with the use of laughing gas in dentistry.
After receiving laughing gas at your dental appointment, it is likely that you will be able to drive yourself home safely – but you must wait until you’re fully awake and alert. This, on average, takes approximately 15 minutes.
To prepare your body for laughing gas, eat a light meal before your procedure. This can prevent any nausea and vomiting resulting from receiving nitrous oxide. Once your dental procedure is complete, avoid any heavy meals for at least three hours after receiving laughing gas.
Be mindful of any signs and symptoms of an allergic reaction after nitrous gas use – symptoms or signs of an allergic reaction might include:
- chills
- hives
- difficulty breathing
- fever
- Wheezing
If you have any of the signs or symptoms listed above, seek immediate medical attention.
Second Thing To Know…
Potential Long-Term Side Effects Associated with The Use Of Laughing Gas In Dentistry
Are There Any?

Any side effects from the use of nitrous oxide in dentistry typically will reverse themselves rather quickly. Laughing gas is not known to cause any long-term side effects.
If you develop unusual symptoms after receiving laughing gas or if a side effect continues for a prolonged period after your procedure, talk with your Lincoln, NE dentist.
Keep in mind that although nitrous oxide is exceptionally safe, it’s not recommended for use by everyone. Your Lincoln, NE dentist or doctor will determine whether nitrous gas is appropriate for you based on your medical history.
Although there have not been any known long-term side effects, the long-term exposure or misuse of nitrous oxide in a working environment could cause long-term complications. There are, however, some contraindications or reasons you should not receive laughing gas. They include:
- Being in the first trimester of pregnancy
- A history of COPD (chronic obstructive pulmonary disease) or other respiratory illness
- Methylenetetrahydrofolate reductase (MTHFR) deficiency
- You have a Vitamin B-12, cobalamin deficiency
- History of any mental health conditions
- History of substance use disorders
Toxic exposure could lead to anemia or a vitamin B-12 deficiency. A vitamin B-12 deficiency that is severe enough can cause damage to nerves resulting in numbness or tingling in your limbs, including fingers and toes.
Third Thing To Know…
Side Effects Associated with The Use Of Nitrous Gas In Dentistry with Children, Including Toddlers –
Is It Safe?

Laughing gas is considered safe for children, including toddlers. Like adults, children (including toddlers) who receive nitrous gas could experience short-term side effects, which include:
- nausea
- fatigue
- shivering
- headache
- Vomiting
Your child may also appear irritable or slightly disoriented after receiving nitrous oxide. Again, just as in adults, these effects will wear off quickly and won’t cause any long-term problems.
Fourth Thing To Know…
Symptoms of A Nitrous Oxide Overdose
How Will You Know?
Although laughing gas is safe when administered adequately within the medical field, there is still a potential risk of overdose. An overdose of laughing gas can occur from receiving too much of the gas or long-term exposure.
Signs of a possible overdose might include:
- Irritation of the throat, eyes, and nose
- Coughing, wheezing, or difficulty breathing
- Chest tightness or choking
- Seizures
- Bluish toes, fingers, and lips
- Increased, rapid heart rate (tachycardia)

It is important to note that any overdose effects require an amount that is several times greater than what someone would receive at their Lincoln, NE dental clinic.

Why do some dentists choose not to use laughing gas?

How much does nitrous oxide cost?
Usually, the gas is sufficient for those who experience mild to moderate anxiety. Depending on your dentist, nitrous oxide costs often $100 or less.
