General Dentist Near Me
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!
Omg!! This place is Amazing! The people who work here are so very nice and understanding. I love this team
Response from the owner:Thank you so much for your kind words! We truly appreciate your support and are grateful to have such wonderful patients.
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!

Types of Dental Anesthesia and Their Duration

Different dental procedures require different types of anesthesia, each with a timeline for wearing off. Let’s explore how long you can expect to experience numbness based on the type of anesthetic used.

Local Anesthesia

Local anesthesia, the most common type used in dental procedures, typically lasts between 2 and 4 hours. However, various factors can influence this duration. The specific medication used plays a significant role:

  • Lidocaine, the most commonly used local anesthetic, usually provides numbness for 1-2 hours. This short-acting anesthetic is perfect for brief procedures like simple fillings or quick repairs.
  • Articaine offers slightly longer numbness, typically lasting 2-3 hours. Dentists often choose this option for procedures requiring more time, such as root canals or crown preparations.
  • Bupivacaine, a long-acting anesthetic, can provide numbness for up to 8 hours. This option might be selected for extensive procedures or when extended pain control is beneficial.

Factors Affecting Anesthesia Duration

Several factors can influence how long dental anesthesia lasts in your system:

  • Body Mass and Metabolism: Your body weight and metabolic rate can affect how quickly you process the anesthetic. Generally, people with faster metabolisms may find the numbness wearing off sooner.
  • Injection Location: The location of the injection in your mouth matters. Anesthesia in the lower jaw typically lasts longer than in the upper jaw due to bone and tissue structure density.
  • Individual Sensitivity: Some people naturally process anesthetics more quickly or slowly than others. Your personal history with anesthesia can help predict how you might react.

Managing the Recovery Period

While the anesthesia is wearing off, it’s important to take certain precautions:

  • Avoid eating until you regain feeling to prevent accidentally biting your cheek, tongue, or lips. When you do eat, start with soft foods at room temperature.
  • Be careful with hot beverages, as you might not be able to feel if they’re too hot, potentially leading to burns.
  • Consider scheduling important meetings or presentations for another day, as speaking might be difficult while you’re numb.

Special Considerations

Children and Anesthesia

Children might need extra attention while the anesthesia wears off. They may be more likely to bite their lips or cheeks accidentally. Close supervision during this period is essential.

Elderly Patients

Older adults might metabolize anesthesia differently, sometimes experiencing longer periods of numbness. They should be particularly careful about eating and drinking while numb.

How to Prevent Tooth Sensitivity

When to Contact Your Dentist

While extended numbness is usually not a cause for concern, certain situations warrant contacting your dental office:

  • Numbness lasting significantly longer than expected (more than 5-6 hours for standard procedures)
  • Development of unexpected symptoms like severe pain or swelling
  • Complete lack of feeling after the expected wearing-off period
  • Persistent altered sensation in the treated area

Tips for Speeding Up Recovery

While you can’t drastically accelerate the wearing-off process, certain activities might help:

  • Gentle facial massage (once approved by your dentist)
  • Light physical activity to increase circulation
  • Staying hydrated
  • Maintaining normal body temperature

Planning Around Your Procedure

When scheduling your dental procedure, consider the anesthesia duration in your planning:

  • Allow enough time for the numbness to wear off before important events
  • Arrange transportation if necessary
  • Plan meals accordingly
  • Schedule important meetings or presentations for another day
