My son is Autistic and he loves it there.
It’s always scary to put your child with disabilities under anesthesia. So it’s a relief to have such compassionate professionals to rely upon They are so sweet and kind to him it’s so nice to have people who genuinely care.

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.

The entire team at The Dental Anesthesia Center is exceptional.

Not only is Dr. Hoffmann a 10/10 dentist, but he is very trustworthy and only recommends procedures when necessary.

The dental hygienists are uniformly wonderful. During cleanings, they are gentle but are still able to carry on a conversation as they work.

If i moved an hour away, I would still drive my family here for any dental needs.
Response from the owner:Thank you for your wonderful review! We’re so grateful for your trust in our team and are glad your experience with our doctors and hygienists has been a positive one. We truly appreciate your support!
I love this dentist office! Everyone is so friendly and accommodating. Dr. Thoms is an excellent dentist that listens to you and makes sure everything is done to your satisfaction. They do TRUE dental sedation. Not just give you a pill like other offices’s that claim they do sedation. Since I am allergic to medicine a dentist normally uses I have to be truly sedated to have work done on my teeth. They do Botox for teeth grinding and TMJ also
Response from the owner:Thank you for the kind 5-star review! We truly appreciate your thoughtful feedback and are glad you had a positive experience with our team and services. Your trust means so much to us.

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
