This dental practice is excellent with my daughter (25 y/o with autism). The entire team is kind, patient, and understanding. They take time to explain what will be happening and only recommend procedures that are truly necessary.

The staff never rushes and makes patients feel comfortable and supported. They are very in tune with sensory challenges. It’s clear they care deeply about creating a positive experience and treating everyone with dignity.

We heartily recommend Dr. Hoffmann and his team.

Best decision I ever made was coming here. Highly recommend. The front office is great, Lena is awesome and docs are so good. Plus you get sweet glasses while they work 😎
Dr. Thom and the entire staff at the Dental Anesthesia Center were warm, friendly and welcoming to me and my husband. My husband has dementia and needed extensive dental work. Dr. Thom took the time to explain to me what needed to be done before the procedure began. My husband is now fully recovered and doing just fine. I'm so grateful that we were referred to the Dental Anesthesia Center. Thank you!!

The Dental Anesthesia Center (DAC) is awesome. When I started there 19 years ago my dental health had deteriorated and my fears were intense. Their expertise and compassion got me back on the right dental track. I still get nervous - but things are so much better now in terms of my dental and gum health.. Don't lose hope - try the DAC!

My appointment today was for a cleaning - and a standard check of gum health etc. Carrie - as always - did EXCELLENT work. She is very kind and thorough and knowledgeable .. and patiently answers all my questions. Carrie is positive and supportive with us patients ... and provides guidance on better at-home care for our teeth and gums.

My thanks also to the office staff who are very helpful with questions or concerns.
Response from the owner:Thank you for your continued trust and kind words! We're honored to have be part of your journey. It means so much to know we've made a lasting impact—your story is truly inspiring!

What Is Sedation Dentistry?

Sedation dentistry uses medication to help patients relax or sleep during dental procedures. This approach is particularly useful for patients who experience:

  • Dental anxiety or fear
  • A strong gag reflex
  • Difficulty sitting still for long periods
  • Low pain tolerance
  • Sensitivity to dental instruments and procedures
  • Special needs or medical conditions requiring extra care

Whether you need a routine cleaning, fillings, extractions, or complex dental work, sedation dentistry ensures a calm and pain-free experience.

Types of Sedation Dentistry Available in St. Louis

  • Nitrous Oxide (Laughing Gas)
    • A mild sedative inhaled through a mask.
    • Helps patients feel relaxed but fully conscious.
    • Wears off quickly, allowing you to drive yourself home.
    • Ideal for mild anxiety and short procedures.
  • Oral Sedation
    • A prescribed pill taken before the procedure.
    • Induces deeper relaxation, but you remain awake.
    • Often used for patients with moderate anxiety.
    • Requires a companion to drive you home.
  • IV Sedation
    • Administered through an IV for a deeper state of relaxation.
    • Most patients have little to no memory of the procedure.
    • Ideal for longer treatments and severe dental anxiety.
    • Requires a ride home and some recovery time.
  • General Anesthesia (Sleep Dentistry)
    • The patient is completely unconscious throughout the procedure.
    • Best for extreme dental fear, special needs patients, or complex surgeries.
    • Administered by a certified dental anesthesiologist.
    • Requires careful monitoring and post-procedure recovery.

Who Can Benefit from Sedation Dentistry?

Sedation dentistry is an excellent choice for:

  • Patients with dental phobia who have avoided treatment for years.
  • Children and adults with special needs who need extra support.
  • People with severe gag reflexes that make dental work difficult.
  • Those undergoing multiple procedures in a single visit.
  • Patients who experience discomfort or pain easily.

If any of these situations sound familiar, sedation dentistry in St. Louis may be the perfect solution.

How to Prepare for Your Sedation Dentistry Appointment

Before Your Visit:

  • Discuss any medical conditions or medications with your dentist.

  • Arrange for someone to drive you home after the procedure.
  • Wear comfortable clothing to help you relax.
  • Avoid alcohol and caffeine the day before your appointment.

During the Procedure:

  • Your dentist will administer the chosen sedation method.
  • You will feel deeply relaxed or even unaware of the procedure.
  • Your vital signs will be monitored for safety throughout treatment.

After Your Visit:

  • If using nitrous oxide, you can resume normal activities.
