“Laughing gas” can be a lifesaver for patients who experience anxiety while in the dentist’s chair.

Sedation dentistry helps many persons receive much needed dental treatment that would be difficult to perform without these relaxing medications. However you may wonder, is laughing gas enough to help you go through the procedure?

I took my son to an appointment today with Dr. Hoffman. We had a great experience from the time we arrived until we departed. The receptionist was very friendly and helpful. The dental assistants were very helpful and polite with my son. The doctor is very kind and patient. They explain everything as we went through the process. We were aware of the cost from the beginning to the end and we're allowed to make decisions about how to handle my child's care and not shocked with additional charges after the fact. My child does not resist going to this office. Great experience.
Always nice and professional doctors and staff! Highly recommend especially if you have dental anxiety!
Response from the owner:Thank you for your kind words! We’re so glad you felt comfortable with our team. We truly appreciate your recommendation!
Dr. Thoms and everyone of his staff members are incredible. I was warmly welcomed and made to feel comfortable and relaxed. Which is saying something as I had not been to the dentist in years due to fear/anxiety.
My procedure was clearly explained. The office staff was beyond helpful with payment and insurance.
The day of my appt was exactly as planned. We started ahead of schedule! The technicians and assistants were clearly skilled and again, helped ease my nervousness. We finished all work as planned. And then Dr. Thoms sat with me and my husband to discuss “everything.” He is very thorough. And finally one of his staff wheeled me down to the elevator, out across the parking lot, and helped me into my van. Now that is service!
Around 8:30 p.m. my cell phone rang and it was Dr. Thoms calling to check up on me. Wow!!!!! This man has all you could want in a dentist—kind, compassionate, thorough, understanding, excellent communicator, and skilled.
I cannot come up with the best words to so highly recommend the Dental Anesthesia Center. It was a remarkable, yet simple, but thorough experience for me.
If you are putting off going to the dentist and have anxiety or fears please call them. They will gently and competently take care of you.
And no, this is not an advertisement/ commercial—I am a real live (satisfied) patient.
Response from the owner:Thank you so much for your kind and thoughtful review! We’re honored to hear that you felt welcomed, comfortable, and well cared for throughout your experience. Our team is dedicated to providing compassionate, thorough care—especially for those who may feel anxious about dental visits—so it means a lot to know that came through. We truly appreciate your recommendation and are grateful you chose us for your care.
The practice is top notch. Could not ask for better care.
Response from the owner:Thank you for your kind words! We’re grateful for your feedback and are proud to provide high-quality care in a supportive environment.
Great practice and nice people. I've been going there for 25+ years!!!
Response from the owner:Thank you for the kind review ! We appreciate that beyond words! It has been our pleasure having you as our patient! We look forward to seeing you at your next dental visit!

What Is “Laughing Gas”?

You probably heard anecdotes about laughing gas at the dentist, and the nickname it has surely sparked an interest. Laughing gas is actually nitrous oxide, an odorless, non-irritant gas that is administered through inhalation before and during certain procedures, alleviating pain and helping the patient relax.

This type of sedation is ideal for people who also experience anxiety about needles and syringes. It is painless and comfortable to administer it, which often makes laughing gas great for children.

Is It Efficient?

Now that we laid the basics of what laughing gas is, you probably wonder if it is the right sedation for you. The answer is, inhalation sedation is generally safe for most patients.

However, is laughing gas enough to keep you sedated if you need to undergo a lengthy procedure or a complex one? Will it keep the pain down during the treatment? Will it last long enough for the dentist to finish the procedure before you get too anxious?

While these are certainly valid concerns a patient may have, rest assured that your St. Louis sedation dentist will consider all the factors before making a decision. He will choose the best sedation method for your medical background and the procedure that you need.

Laughing gas is, in fact, often recommended for short procedures, as its effects wear off fast. It is the only sedation method that may allow you to leave and drive yourself after the treatment. As soon as the doctor takes the mask off, you generally have a few minutes before the effect wears off.

Can You Still Feel Pain with Laughing Gas?

Laughing gas, or nitrous oxide, is highly effective at reducing anxiety and helping patients relax during dental procedures. However, it’s important to understand that laughing gas alone does not completely block pain. Instead, it creates a calm, euphoric state, allowing you to tolerate discomfort more easily.

For procedures that might cause pain, your dentist will typically combine laughing gas with a local anesthetic to numb the area being treated. The laughing gas helps you stay calm and less focused on the sensations, while the anesthetic ensures you don’t feel pain during the procedure.

If you are concerned about pain or discomfort, be sure to discuss this with your dentist. They will tailor your sedation and pain management plan to your specific needs, ensuring that you feel as comfortable as possible throughout your treatment.

How Will Inhalation Sedation Feel?

We have mentioned anecdotes that you may have heard about inhalation sedation. Most of these stories are exaggerated, of course. One common theme is that you will fall asleep during the procedure. While it is possible to feel so relaxed that you will actually fall asleep, it doesn’t happen every time. You will feel a tingling sensation in your limbs, a good warm feeling taking over you, grogginess and relaxation. You will most probably not remember anything from the procedure.

These sensations will help you stay calm and accept the treatment with no problems. Laughing gas is a great way to receive the treatment you need if you experience a lot of fear related to going to the dentist.

Next time you have an appointment with your St. Louis sedation dentist, discuss the possibility of being administered inhalation sedation. Your doctor will explain the risks, benefits and you will decide together if it is the right option for you.
