Laughing Gas

Rotate -90 degree (49)

What is Laughing Gas?

Laughing gas, also called nitrous oxide, is a mild sedative inhaled through a small mask placed over your nose. It’s sometimes referred to as happy gas because it helps patients feel relaxed, comfortable, and in control during dental procedures.

Unlike deeper forms of sedation, you remain awake and able to respond to instructions. The administration is non-invasive, allowing you to breathe normally while the dentist controls the amount of gas to keep you comfortable throughout the procedure. It is safe for most patients, including children and adults, and is especially useful for those with dental anxiety, sensitive teeth, or longer treatments.

The Science Behind Laughing Gas

Laughing gas works by interacting with the body’s nervous system in several ways. When inhaled through a mask mixed safely with oxygen, it quickly enters the bloodstream via the lungs and reaches the brain.

Here’s how it helps patients feel calm and comfortable:

  • Reduces pain perception – it helps the brain experience less discomfort.
  • Relieves anxiety – it calms the nervous system and lowers stress levels.
  • Promotes a relaxed feeling – patients feel light, comfortable, and at ease.
Unlike general anesthesia, nitrous oxide does not put you to sleep. You stay awake and responsive. This controllable effect is why nitrous oxide sedation is widely used in dentistry for both children and adults.

Is Laughing Gas Right for Me?

We know that a trip to the dentist isn’t always the easiest thing. For many people, even something simple like a routine dental checkup can bring on feelings of worry, nervousness, or fear of pain.

 

At Dental Designs Clinic, we offer laughing gas (also known as nitrous oxide sedation) to help you feel comfortable throughout your treatment. It can be helpful if you experience:

  • Dental anxiety or nervousness

  • Fear of dental procedures (dental phobia), including children who feel uneasy at the dentist

  • Have very sensitive teeth

  • Have low pain tolerance

  • Difficulty staying still during dental procedures due to a strong gag reflex

  • Nervousness during longer or more complex treatments, such as root canal treatments or tooth extractions

How Dental Designs Clinic Can Help with Dental Anxiety

Pick a Good Time

Try to schedule your dental visit when you feel calm and relaxed. Avoid busy periods and give yourself extra time before and after, so you’re not rushed. Checking with our receptionist about quieter hours can make your experience smoother and more comfortable.

Share Your Fears

It’s completely normal to feel nervous. Let our dentist and team know so we can adjust the treatment to help you feel at ease. Listening to music or imagining a relaxing place can also be soothing, and headphones can distract from clinic sounds like the drill.

Take It Slow

Your first visit is all about getting comfortable with your dentist and the clinic environment. You can agree on a signal if you need a short break. Sharing any specific worries or past experiences helps us provide the support you need throughout your visit.

Bring Support

Bringing a friend or family member along can make your visit more reassuring. They can sit with you during treatment or keep you company in the waiting area. Having someone familiar nearby helps you feel calmer and more confident throughout the appointment.

Is Laughing Gas Safe For Me?

Laughing gas, or nitrous oxide sedation, is a safe and commonly used option to help you feel relaxed during dental treatment. It works quickly, wears off soon after the procedure, and allows you to stay awake and responsive.

Because you stay conscious, you can communicate with your dentist during the procedure, which makes the experience feel secure and personal. Many patients describe it as feeling light, calm, and even a little floaty, but always in control.

Before any sedation, our team will review your medical history to ensure laughing gas is appropriate for you. While very safe, there are certain situations, such as specific medical conditions or pregnancy where we may recommend alternative options.

Can you still feel pain with laughing gas?

Laughing gas helps you feel calm and less sensitive to discomfort, but it doesn’t completely block pain. That’s why for treatments that could cause significant discomfort, such as deep cavity fillings or tooth extractions, dentists still use local anesthetics. Local anesthetics are applied directly to the treatment area to numb the nerves, ensuring that you don’t feel sharp pain while the dentist works.

 

Using laughing gas and local anesthetic together allows for a comfortable dental experience.

Benefits of Laughing Gas in Dentistry

Rotate -90 degree (53)aa

Laughing gas (nitrous oxide) helps you feel calm and relaxed during your dental visit. It eases nervousness and makes procedures more comfortable. Many patients feel relaxed and in control throughout their treatment.

The laughing gas is delivered in a controlled manner, and you stay fully awake and responsive, so you can feel confident and at ease during your appointment.
One of the biggest advantages of laughing gas sedation is how quickly it wears off. Once the mask is removed, the calming effect disappears within minutes, so you can usually go about your day immediately after your appointment. This makes it a convenient option for busy adults and families alike.

Laughing gas works for a wide range of dental treatments, from check-ups and fillings to root canals and more complex procedures.

Children who feel nervous about the dentist can benefit from laughing gas. It gently calms them, making treatment easier and more positive. Parents often notice their children feel more relaxed and less anxious in future visits.

Other Sedation Techniques Available at Dental Designs Clinic

We understand that every patient is different, which is why we offer multiple sedation options to make your dental experience comfortable. Besides laughing gas sedation, we also provide local anesthetic and IV sedation.

Local Anesthetic

Local anesthetic numbs only the area being treated, so you stay fully awake but feel no pain. It’s ideal for most routine procedures like fillings, root canal treatments, or tooth extractions. The anesthetic is injected directly into the treatment site, working quickly to block pain.

IV Sedation

IV sedation helps you feel deeply relaxed. You remain conscious enough to respond if needed, but may have little memory of the procedure. This makes it ideal for complex treatments or for patients with high dental anxiety.

Laughing Gas for Children

Laughing gas is a gentle and safe sedation method that helps make dental appointments calm and comfortable. It creates positive experiences, easing fear of future visits and encouraging a lifetime of healthy smiles.

It also works quickly and wears off fast, so your child can return to their usual activities shortly after their visit.

This dental clinic has very good staff who are well trained and friendly. The dentists are also very good and will explain the treatment in detail before starting treatment. The equipment is very high tech and I believe they are able to do high quality work as I did my crown here and it looks much better than my colleague who also recently did his at another place. The waiting room is also very comfortable. good job!

C. Zheng De

This clinic is one of the best I have ever seen. I saw dr Justin for my implant which I did many years ago, the tooth was loose, and other drs told me to remove it as they could not find out what brand it was but dr Justin was able to take 3d xrays and locate the brand and specially ordered the part in. he saved me from having to do a surgery to remove and put a new implant which would have cost me a bomb. the tooth looks even better than the original thanks to the experieced dental technician Katsuya from Japan. 

Very happy and will keep coming back for my regular dental. 

G. Hock An

my workplace is close by and I had a problem with my tooth for a few days, so I made an appointment to come down. The receptionist who booked my appointment was very helpful and friendly to explain the way to the clinic from my office. I saw Dr Nicholas who was able to do a root canal treatment on the same visit so that I didn't need to come back. I felt safe and comfortable to do my dental treatment here as the dental picks are all wrapped up and sterilized and only opened before each treatment when im inside.
