If you or a loved one feels anxious about visiting the dentist — or requires extensive dental work — you may wonder: Is IV sedation or general anesthesia the better option? At The Dental Anesthesia Center in St. Louis, we offer both, and each plays a unique role in helping patients receive safe, stress-free care.
This article breaks down the key differences between IV sedation and general anesthesia, including their benefits, safety, and which may be right for you or your child.
What Is IV Sedation?
IV sedation involves delivering medication through a vein to help patients feel deeply relaxed. You remain conscious but typically have little to no memory of the procedure. It’s often called “twilight sedation.”
Key benefits of IV sedation include:
Fast-acting relaxation
Minimal awareness of the procedure
Short recovery time
Ideal for moderate anxiety or lengthy dental work
What Is General Anesthesia?
General anesthesia puts the patient completely to sleep. This method is used when the patient must be unresponsive during treatment — such as for complex procedures, special needs patients, or severe dental phobia.
Benefits of general anesthesia:
Complete unconsciousness (no awareness or memory)
Controlled by a trained dental anesthesiologist
Best for patients who cannot tolerate dental care while awake
Often used for special needs dentistry or pediatric cases

Which Option Is Right for You?
Choosing between IV sedation and general anesthesia depends on several factors:
The patient’s level of anxiety or dental phobia
Medical history or special needs diagnosis
The length and complexity of the procedure
Age and ability to cooperate during treatment
At The Dental Anesthesia Center, our team includes board-certified dental anesthesiologists who evaluate each patient and recommend the safest, most effective sedation option.
Is It Safe?
Yes — when administered by licensed professionals in a properly equipped setting. Our St. Louis office is one of the only dental practices in Missouri licensed to offer in-office general anesthesia. Safety is our top priority, and we follow strict patient monitoring, screening, and recovery guidelines.
Outstanding customer car for our 15 yrs old Autistic Granddaughter. Rebekah really helped put our minds and ease and helped us plan the next visit when it came to reservations we had on the cost of this treatment, and future ones. This is expensive, but worth it knowing they help special needs kids, teens and adults. Sedation dentistry team handle everything great! Thank you Dr. Thoms and the team!!

Dr Thoms specializes in dental anesthesia for patients with Special Needs. My daughter has been a patient of his for many years. His experience, depth of knowledge and understanding the needs of Special Needs patients is excellent. He presents clear and detailed information for his procedures and treatment options along with expectations during aftercare. Follow up instructions include a personal phone call from him as well as additional calls from his office staff. I highly recommend Dr Thoms and definitely give him 5 stars.

My hygienist, DeLaina Joost, takes excellent care of my teeth with her advanced skills, gentle touch and great “chair side” manner. She is a consummate professional, and such a compassionate person. I look forward to my visits at DAC!

I want to thank everyone at the Dental Anesthesia Center for taking care of me yesterday—Meaghan helped me get the forms filled out correctly and in on time, Daisy for guiding me in and getting me out safely, Dr. Hoffman for taking care of my teeth and dealing with my really terrible gag reflex, and EVERYONE who helps make this happen. I don't know all of your names, but I do know that it takes all of you working together to make my dental care possible and have good results.
I'm always nervous when I first arrive, even though every procedure has had a good outcome. I've never had any pain or excessive bleeding as a result. The one thing I realized yesterday is that all of you are warm, friendly, positive, you have what is called a good vibe, which helps me a great deal.
Response from the owner:Thank you for your kind words and for taking the time to share your experience. We’re so glad our team could help you feel comfortable and supported throughout your visit. Providing a safe, positive environment is very important to us, and your feedback means a great deal. We truly appreciate your trust in our care!
Dr. Thoms and his entire staff at The Dental Anesthesia Center have been absolutely wonderful!! They're all so kind and knowledgeable. I would give them 10 stars if I could!!!
