Debbie H.

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 15 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

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.

Response from the owner:Thank you for your kind words and for taking the time to share your experience. We’re grateful for the trust families place in our team and are committed to providing thoughtful, individualized care with clear communication every step of the way. Your recommendation means a great deal to us!

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!

Response from the owner:Thank you for your kind words! We’re so glad to hear you had a positive experience with our team and appreciate you taking the time to share your feedback.

Ken C.

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!

What Is Sedation Dentistry?

Sedation dentistry involves using medications to help patients relax during dental procedures. The level of sedation depends on the type used and the patient’s needs. There are four main types:

• Nitrous Oxide (Laughing Gas) – A mild sedative inhaled through a mask that helps patients feel relaxed but awake.
• Oral Sedation – A pill taken before the procedure, typically a benzodiazepine like Valium or Halcion, that induces a drowsy, relaxed state.
• IV Sedation – Medication administered through an intravenous line, offering deeper sedation with adjustable levels.
• General Anesthesia – The deepest level of sedation, rendering the patient completely unconscious; used for major surgeries or severe dental phobia.

Common Side Effects of Sedation Dentistry

While sedation dentistry is considered safe and effective, some patients may experience temporary side effects. The severity of side effects depends on the type of sedation used, the patient’s medical history, and individual sensitivity to the medications.

Drowsiness and Grogginess

Drowsiness is the most common after-effect of sedation, particularly with oral sedation, IV sedation, and general anesthesia. Depending on the sedative, this effect can last a few hours to a full day. (American Society of Anesthesiologists (ASA), 2023)

• Why It Happens: Sedatives depress the central nervous system, slowing brain activity.
• How to Manage: Rest for the remainder of the day and avoid operating heavy machinery or driving.

Nausea and Vomiting

Some patients experience mild nausea after sedation, particularly with general anesthesia or IV sedation. This is more common in patients prone to motion sickness or with an empty stomach before the procedure. (National Institute of Health (NIH), 2023)

• Why It Happens: Some sedative medications can affect the stomach and inner ear balance.
• How to Manage: Drink small sips of water and eat light, bland foods after your procedure.

Dry Mouth

Sedation medications, particularly oral benzodiazepines, and IV sedatives can cause dry mouth by reducing saliva production. (American Dental Association (ADA), 2023)

• Why It Happens: Sedatives affect the salivary glands and nervous system.
• How to Manage: Drink plenty of water, chew sugar-free gum, and use a saliva substitute if needed.

Headache

Headaches can occur, especially after nitrous oxide sedation, when oxygen levels fluctuate. (Mayo Clinic, 2023)

• Why It Happens: If nitrous oxide is not flushed out properly with oxygen, it can cause mild headaches.
• How to Manage: Ensure your dentist administers oxygen for a few minutes post-procedure and stays hydrated.

Temporary Amnesia (Memory Loss)

Patients receiving oral sedation, IV sedation, or general anesthesia may have little to no memory of the procedure. (National Library of Medicine, 2023)

• Why It Happens: Sedatives like benzodiazepines can cause short-term memory loss as they inhibit brain activity.
• How to Manage: Memory function typically returns to normal within a few hours.

Low Blood Pressure and Dizziness

Some sedation methods, particularly IV sedation and general anesthesia, can temporarily lower blood pressure, causing dizziness or lightheadedness. (American Heart Association (AHA), 2023)

• Why It Happens: Sedation slows the heart rate and relaxes blood vessels.
• How to Manage: Get up slowly from a lying position and drink fluids.

How Long Do Sedation Side Effects Last?

• Nitrous Oxide: Wears off within 5–10 minutes after stopping the gas.
• Oral Sedation: Effects can last 4–6 hours, with some residual drowsiness for up to 24 hours.
• IV Sedation: Effects wear off in 6–12 hours, but full recovery can take 24 hours.
• General Anesthesia: It can take 24–48 hours for full recovery.

When to Call Your Dentist

While most sedation side effects are mild and temporary, contact your dentist if you experience:

• Severe nausea or vomiting lasting more than 24 hours.
• Excessive bleeding, swelling, or pain.
• Confusion or difficulty breathing.

Sedation Dentistry is Safe and Effective

Sedation dentistry is an excellent option for patients with anxiety, phobias, or medical conditions that make traditional dental care challenging. While side effects like drowsiness, dry mouth, or dizziness can occur, they are temporary and manageable. Understanding what to expect can help you prepare for a smooth, stress-free dental experience.
