While nitrous oxide (also known as laughing gas) is generally safe, there are certain patients it is not recommended for.
Commonly known as laughing gas, nitrous oxide is a type of inhalation sedation that has been widely used in sedation dentistry since the 19th century when it was introduced to medicine. It is generally one of the safest substances that is used in sedation dentistry, as it’s effect doesn’t last long.
Great experience every time! The staff is welcoming, gentle, and truly cares about their patients.

The Dental Anesthesia Center and Dr. Thoms have been a life saver for our daughter. She has always struggled with the dentist due to her rare neurological condition, we initially contacted them for her wisdom teeth removal and now see them for her ongoing dental care. Their advanced care and support make it possible for her to receive the best treatment and keep her teeth healthy.
Response from the owner:Thank you for your kind words and trust in our team. We're honored to be part of your daughter's care and are committed to providing compassionate, high-quality treatment for every patient.
I recently began attending as a patient and it has been nothing but a positive experience. I had my wisdom teeth removed and I went in fell asleep and when I woke up I was done and ready to go. The staff are friendly, understanding, and professional. I would absolutely recommend anyone to go here for any dental needs.
Response from the owner:Thank you for sharing your experience! We’re so glad to hear your visit went smoothly and that you felt comfortable and cared for by our team. We truly appreciate your recommendation!
Dr. Sean Thoms is kind, compassionate and knowledgeable! He explained every detail of my daughter’s complicated dental procedure in an easily understood manner. He even called later to ensure that my daughter was recovering well! All of the staff were extremely nice and professional. For these reasons, and more I would highly recommend Dr. Sean Thoms at The Dental Anesthesia Center!
Response from the owner:Thank you for your kind words about Dr. Thoms and our team! We’re grateful for your trust and so glad to hear your experience was a positive one. We truly appreciate your recommendation!
My mother recently received care from Dr. Hoffman. She was so thrilled with her experience with the treatment she received from Dr. Hoffman and Robin I felt compelled to write a review myself! She was extremely nervous and they made the procedure quick and painless!! Thank you Dr. Hoffman and your entire team!! I will absolutely recommend this office for anyone in need of dental work in St. Louis!
Response from the owner:Thank you for taking the time to share such kind feedback! We're so glad your mother had a positive experience with Dr. Hoffmann and our team. We truly appreciate your recommendation!
This is my second time seeing Dr. Hoffman.
He is so proficient and makes the entire experience extremely comfortable! He removed my wisdom teeth, no pain, and had them out within seconds. I highly recommend him and his office staff to anyone in the St. Louis area!!!

I was referred to The Dental Anesthesia Center by a dentist who thought I was "afraid of dentistry" because I couldn't stand to be touched in a certain area of my mouth. Thankfully I met Dr. Sean Thoms, who discovered the source of the pain was a severed nerve along my gumline caused by a previous oral surgeon.
DR. THOMS, HIS NURSES AND THE STAFF ARE THE BEST OF THE BEST!! Trust me, I have had extremely complicated dental issues since 2007 bouncing from dentist to dentist. None of which were able to help me.
Dr. Thoms went over and above the call of duty - researching and conferring with other professionals in his field before coming up with a plan of action. He didn't give up on me!
THIS DR. AND HIS TEAM CARES ABOUT YOU! It is the best decision I could have made and now my smile starts from the inside out!!

Dr. Thom, Rebekah, and the rest of the staff were absolutely amazing with my 9 year old special needs son! We just moved back to MO after living in SC for years and hadn't been able to establish care with anyone yet when we had an accident where my son broke his front tooth and it needed to be removed. Under sedation, Dr. Thom was able to perform a complete set of x-rays that we weren't able to obtain in SC and he was able to show us where a couple of his adult teeth that haven't erupted yet were blocking each other and that the pre-molar would have to be removed eventually anyway in order to give his K9 tooth the best chance to come in normally. He took the time to explain everything and show us directly in our son's mouth as well as on the x-rays what was needing to be done for the best possible outcome. The ladies were so awesome and patient with him as he was coming out of anesthesia and cranky. Dr. Thom called to check on him that evening and it was reassuring that we could contact him at anytime with questions or concerns! This morning our son actually smiled and showed off his jack-o-lantern smile that he will have for the next few years until he is old enough to get something more permanent done. We have definitely found our dentist for the entire family!!
Response from the owner:Thank you for your kind words! We’re so glad our team was able to provide the care and support your family needed during a stressful time. We truly appreciate your trust in us and look forward to continuing to care for your family!
Omg!! This place is Amazing! The people who work here are so very nice and understanding. I love this team

I will always sing the praises of this office. Their care and compassion are beyond amazing!
Response from the owner:Thank you so much for your kind words, they mean the world to us.
I went to DAC because I have a hearing impairment which makes the sounds of dental work incredibly painful. (Bone conduction)
Because of this, I had not been to the dentist in years.
Being able to go to sleep and have all my dental work done while I was out was incredible! I had a tooth extracted, a root canal, 4 fillings and a cleaning all at the same visit!
The staff was so caring and understanding, it made me feel really good.
I will only go here for my dental work from now on.

Response from the owner:Thank you for your thoughtful review! We’re so glad to hear you’ve had positive experiences with our team. Your referrals mean a lot to us!
Had an apt for a new dentist (insurance would not cover our old one anymore). It was supposed to be just an evaluation/ cleaning. But I developed severe dental pain Wed and yesterday was really bad. The new office does an incredible job! Not only did The Dental Anesthesia Center - SLEEP DENTISTRY ST. LOUIS change my visit, they found the source of the pain (cracked tooth with previous filling that needed a root canal) bit they FIXED IT and I was relaxed (thanks to the nitrous gas) and had no pain thanks to Dr B & her amazing assistants. I had a good dentist before, but this was the best dental experience I've ever had.
Thank you!
Thank you!

I became a patient of Dr. Hoffman when he was the only dentist and the office was much smaller. I needed a dentist who could safely sedate me when I had dental work done. I've seen the practice grow into the The Dental Anesthesia Center. Dr. Hoffmann, Dr. Thoms, and Dr. Behl can fix any problem with your teeth without being you being anxious. The Dental Hygienists have a special skill of making sure you are calm while sitting in their chair. The office staff do a fabulous job of running the office smoothly. Continuing education is very important in the practice. I like how much everyone on the staff work together to make sure you visit is the best part of your day. The staff participates in several find raising events for local charities. There isn't a better Dentist in St. Louis.
Response from the owner:Thank you for your thoughtful and generous review. We appreciate you taking the time to share your experience with our practice over the years. We are so glad to hear that our efforts in providing compassionate, high-quality care in a calm and supportive environment have made a difference for you. We also truly value giving back to the community and appreciate you noticing. Your support means the world to us!
Dr. Thoms and his staff are wonderful with our special needs daughter. They are kind and patient with her, and always keep us informed during her procedures. We wouldn’t take her anywhere else!
Response from the owner:Thank you so much for your kind words and trust in our team. It means a great deal to know that you feel supported and informed during your visits. We truly appreciate your confidence in us!
Thanks to all the great staff and Dr. Hoffman for all wonderful help you gave to our son.
Thank you

Seeing Dr Hoffman at the Dental Anesthesia Center has been one of the best decisions I have made in my life. Dr Hoffman and all of his staff, the other dentists, the dental assistants and the front desk personnel are the absolute best. Everyone I’ve encountered in the office have been so kind, patient, professional and compassionate. I will always have a degree of dental anxiety, but everyone shows such compassion and understanding, that it really helps make you feel less anxious.
Response from the owner:Thank you so much for your heartfelt review. We're truly honored to be part of your care and grateful for your kind words about our team. Helping patients feel safe, supported, and comfortable is at the core of everything we do. Your trust means the world to us!
Our son, Jimmy Henderson , has been having all of his dental care done by Dr. Michael Hoffmann and his team at the Dental Anesthesia Center for the past 10 years. He goes there once a year and they put him to sleep, clean his teeth, take x-rays and fix anything that needs to be repaired. They are such a blessing for us and our son. He couldn’t tolerate a regular dentist. We heartily recommend them for your dental care. Terry & Debbie Henderson

Dr. Hoffmann and his awesome staff are always on time and do a great job. A very professional group of people providing excellent dental care.
Response from the owner:Thank you for your kind feedback! We’re grateful for your support and proud to provide timely, professional care to our patients.
I am happy to see dentists finding ways to make things easier for those who don't like to go to the dentist. I have even seen some dental offices that have been tricked out to make the little patients to think that he or she is in a much different place than the dentist office. Historically the building was built in the 1950s and the office used to belong to an opthamologist.
Response from the owner:Thank you for your thoughtful review! We're dedicated to creating a comfortable space for all our patients—especially the little ones.
Dr. Hoffman is very skilled. Additionally everyone one on his team and in his office are great. Very compassionate and patient.
Response from the owner:Thank you so much for the 5-star review—we truly appreciate your support!
Absolutely highest quality service and staff! My son was treated so well and it made a scary appointment easier for him to handle. If I could, I’d give 10 ⭐️!
Response from the owner:Thank you so much for your kind words! We're thrilled to hear that your son had a positive experience and that we could make his appointment easier.
Christy and Dr. Behl spent a lot of time with me making sure I was comfortable and my anxiety was not ramping up. They both explained exactly what they were doing before they did it and gave me frequent breaks to catch my breath.
Response from the owner:Thank you so much for your kind words! We're glad you felt comfortable and cared for throughout your visit. Your trust means a lot to us!
Great staff, and great experience!

Love these folks. They go above and beyond. So much so I am a regular dental patient! So gentle and caring, I could not say enough.
Response from the owner:Thank you for the kind words!
I've been with this group for about a decade & can't say enough good things about them. From the dentists to the hygienists to the desk staff, they are fabulous. I have incredibly high anxiety when it comes to dental work & they go out of their way to make me feel as comfortable as possible. I've never had a bad experience & if it wasn't for them I'd still be getting dental cleanings under real anesthesia due to the fear. They turned that around for me & while I still feel anxiety, I'm able to get cleanings without any anesthesia, pills, gas, etc. I've had both large scale & routine work done there & highly recommend them. Extremely helpful, professional & pleasant staff all around. Wonderful people.
Response from the owner:Thank you so much for your trust and kind words! We're honored to have helped you overcome your dental anxiety and appreciate your recommendation.
A 10/10 Experience!
I cannot express how grateful we are for Dr. Thoms and his team! Their sensitivity, expertise, and dedication made a potentially challenging dental experience for our daughter as comfortable and stress-free as possible (for her AND us!).
We were very impressed by Dr. Thoms' thoroughness in explaining the procedure and his willingness to answer all of our questions, alleviating any anxieties we had. The ability to be present by our daughter's side as she was falling asleep was a huge comfort factor.
We felt a sense of genuine care and compassion towards our daughter and felt that they treated her as if she was one of their own. Dr. Thoms and his team clearly go above and beyond to provide exceptional patient care and makes a complex dental procedure feel safe, comfortable, and even reassuring. A huge THANK YOU to Dr. Thoms and his team!

The Dental Anesthesia Center (DAC) is truly unique. They provide all forms of anesthesia - and a wide range of dental treatments. I have been a patient there for 17 years - and I continue to be impressed with the legacy of expertise and kindness built by Dr. Hoffmann and his team.
If your dental phobia and dental issues have made you feel hopeless ... I encourage you to contact the DAC for a consultation. That's what I did 17 years ago - and it proved to be a very good decision and a true blessing.

As a 73 year old man, I have been to several dentist’s and none compare to Dr. Thoms and Dr. Behl. The entire staff is very knowledgeable and accommodating. I have had some major work done and I/V sedation is definitely the way to go. Five stars to the entire team at DAC. I highly recommend their services.

I love my friends at the Dental Anesthesia Center! This place has the nicest clinical staff and they do such a wonderful job for any issue that arises. They are prompt and thorough. I love all the hygienists, but especially my personal hygienist, Carrie. My dentist, Dr. Biehl is knowledgeable, friendly, highly skilled and fun.
I started taking my kids here when they needed procedures under anesthesia. Once my former dentist retired (and I realized the DAC also does family dentistry), I switched the entire family to this office. Best decision I ever made.
I’m also so impressed with the experience this team has treating individuals with special needs.

I went for a consultation at the center. I was terrified. I saw Dr.Sean Thoms he was so professional and caring. I have had five different consultations at other dentist offices trying to make a final decision on who I feel more comfortable with and no other doctor was as caring or attentive as Dr. Thoms. He called me a couple of days later with SEVERAL different ways he could give the results I wanted. I’m truly blessed to have found Dr Thoms. The entire staff was so professional and attentive. I have made the final decision to put my care in the hands of Dr Sean Thoms

Maris E. Behl DDS Is a wonderful dentist. She did extensive work including several dental crowns and fillings. There was little to no pain during all of her procedure’s. I am 86 years old and have been to more dentists than I can count. Dr Behl is by far the best of all. If you want a friendly disciplined and accomplished dentist, you will be glad you used her work.
Response from the owner:Thank you so much for your kind words, James. We really appreciate you taking the time out to share your experience with us.

While it may seem perfectly harmless, laughing gas is still a sedative and should be taken only with a recommendation from your St. Louis sedation dentist, as it can have side effects when interacting with other medications or when administered to a person with an incompatible condition. That is why doctors choose the sedation option that is best for the patient instead of adapting the patient to the medication.
When Is Nitrous Oxide Recommended?
Laughing gas is often recommended when a patient has dentist anxiety or when he has to go through a long and tiring procedure. Sedation is an option also when the gag reflex is stronger than average or when the patient simply wants to make the treatment a bit easier to go through.
When it comes to patients that should not be put under stress, like patients with cardiac bypass or suffering from strong anxiety, administering nitrous oxide will generally make the dental procedure safer, as it takes away the associated stress.
Usually, young children that have to go through a dental procedure have trouble being still and patient for so long. Laughing gas can make the procedure possible.
Why It May Not Be Recommended
Although generally safe, there are times it should not be used. That’s why your St. Louis sedation dentist will check your medical history first before determining the best course of action.
Patients who have limited lung capacity or obstructive pulmonary disease should not be administered laughing gas. The safety of nitrous oxide is given by the fact that it acts quickly and wears out quickly as well. With these patients, however, the gas takes longer to act, as it is absorbed slower, and it leaves the body slowly as well. This greatly reduces the advantage of laughing gas has over other forms of sedation.
Patients who have a stuffy nose and are forced to breathe through their mouths may not be good candidates for nitrous oxide either. Laughing gas is administered through nasal airways and it won’t be as effective if the patient cannot breathe well through their nose.
Patients who cough are also to be administered other kinds of sedatives.
Pregnant women should not be administered nitrous oxide unless it is an emergency and the
Patients with intracranial disorders shouldn’t be administered laughing gas, as it can increase the pressure levels in the skull.
