Our adult daughter has cerebral palsy and requires being fully sedated when having anything done. The DAC was such a positive experience. Dr Hoffmann and his staff were kind and did great explaining things. As a mom, I had a lot of questions about how certain things would be done as usually she’s in her chair when getting examined at her local dentist and they had everything under control including transferring from her chair to the dentist chair and keeping her secured in the dentist chair as well as keeping her neck and legs comfortable. Many thanks to them!

Response from the owner:Thank you so much for your kind words. We’re grateful for your trust and happy to hear that you had such a positive experience with our team. Our goal is always to provide compassionate, attentive care in a safe and comfortable environment. We truly appreciate you taking the time to share your experience.

TWENTY YEARS! That is how long our special needs son has been seeing Dr Hoffman and his dedicated team! Our son suffers from an intellectual disability, is non-verbal, and is unable to cooperate for dental cleaning, x-rays, or other routine dental work. He requires general anesthesia. It is such a blessing to avoid a hospital setting just for dental work.

The team is always well staffed, friendly, personable and very professional. Every single year we have been supported by a deeply caring team who are dedicated to patients with a very wide range of disabilities and needs. They have shared useful dental advice and tools (3 sided toothbrushes, blocks to hold open their mouth for daily at-home care, etc.) which improved our son’s daily dental care. We always receive a call back the day after to check his recovery-even on weekends!

Highly recommended and so appreciative to have this team supporting our ever long road of raising a special needs son.

Response from the owner:Wow — thank you for sharing such a heartfelt review! We are so grateful for your trust and for allowing our team to be part of your family’s journey over the years. It means so much to us to know that our care and support have made a difference. We truly appreciate your kind words and recommendation!

We've been coming to Dr.Hoffman for twenty years. There's a reason we keep coming back! He's great. His staff is great. He's double boarded as an MD (Anesthesia) and DDS!!! Our son with special needs needs sedation for even a cleaning. You get what you pay for. He's expensive and... we know he's getting the best care!

Response from the owner:Thank you for trusting our team over the years and for your kind words about Dr. Hoffmann and our staff. We truly value your confidence in the care we provide!

Searching for a new dental clinic is challenging for someone who has
dental anxiety, fear, and traumatic experiences in a dental chair. The staff and doctors at the Dental Anesthesia Center were immediately very welcoming. Dr. Thoms put together a very detailed plan to repair and replace the previous work that I had in the past that was now causing problems. Putting my faith in him was the best thing that I could have done for my situation. I am more than completely satisfied with all of the extensive dental work that I’ve had with Dr.Thoms. I had my fourth sleep dentistry experience yesterday and I’m very happy with my results. I highly recommend this practice and truly want to give them more than five stars! Thank you for giving me back my health and confidence.

Response from the owner:We know it isn’t always easy to find a dental office where you feel at ease, so your words mean the world to us. We’re so glad you feel comfortable with our team and truly appreciate your trust and recommendation!

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.
