If you are putting off a root canal due to fear or anxiety, it may lead to a serious infection.

For most patients, a root canal sounds overwhelming. The good news is that it doesn’t need to be. If you are afraid of the pain associated with a root canal, the good news is there is a way to have the procedure done with virtually no pain. Sedation dentistry turns a root canal procedure into a comparatively trivial matter. If a root canal is necessary and you are putting it off because of pain or anxiety, it may lead to a serious infection or an abscess.

Great place. Dr Thoms was wonderful, and checked in later in the day to see how I was doing—despite being about to catch a flight, he wanted to make sure I was alright. The nurses were lovely and very accommodating. Thanks for making my wisdom teeth removal under anesthesia so “painless”!
My dental appointment was absolutely amazing! Dr. Behl and Laina performed a thorough examination and cleaning! I couldn’t have asked for a better experience!
Response from the owner:Thank you for your kind review! We appreciate your feedback and are glad you had a positive experience.

Dr. Hoffman and his staff are very good at making the experience for my special needs son, as easy and non stressful as possible for him. It's not easy handling him sometimes but Dr. Hoffman has compassion and grace towards my son and takes his time and doesn't rush thru. I appreciate him and his staff as always and highly recommend this office especially when you need that extra care with dental needs.
Response from the owner:Thank you for your kind words and recommendation. We appreciate your trust in our team and are grateful to be part of providing a positive experience for families in our care.
We had a very positive experience with Dental Anesthesia Center. Dr. Thoms and his entire staff were kind, patient, and understanding throughout the entire process. My child has special needs, and as an anxious mom, I truly appreciated how compassionate and reassuring everyone was. We were referred to Dr. Thoms by our child’s dentist, and they took the time to explain everything while genuinely wanting to do what was best for my son. Communication was excellent throughout the procedure, which helped ease a lot of my anxiety. The office staff, including the ladies who handled the payment process, were just as kind and helpful, and I never felt pressured when discussing treatment or costs. The cost was more than we anticipated and definitely an unexpected expense, but my child’s needs always come first. Most importantly, my son seemed very comfortable afterward, did not appear to be in pain, and was eating an hour after the procedure. I don’t give perfect scores lightly, but I would absolutely recommend Dr. Thoms and his team to other families, especially parents of children with special needs.
Response from the owner:Thank you for your thoughtful review and kind words. We’re grateful for the opportunity to provide care and appreciate you trusting our team. Wishing you and your family all the best!

What is a Root Canal?

When you have a root canal, an opening is made in the crown of your tooth. The dentist removes the tooth’s pulp down to the tip of the roots. Once the infected pulp is removed, the dentist uses a filler to fill the tooth, and then an adhesive is used to ensure that the entire canal root of the tooth is sealed. Once the procedure is done, the dentist places a temporary crown on the tooth. You will then return for another appointment for a permanent crown to protect the tooth against further damage.

It can sometimes be a lengthy process, and since the dentist is dealing with the roots of your tooth, it can be highly sensitive and painful, so many patients avoid it. For a root canal, there are several options for dental sedation that will minimize any feeling you have and, in some instances, any memories you have of the procedure.

You can generally use nitrous oxide, oral conscious sedation, or IV sedation if you get a root canal. The sedation method for an individual is determined by the patient’s medical history and current physical and mental health.

Types of Sedation Available

Minimal sedation is the lightest level of sedation. It involves a mild sedative, such as a Valium-like medication or Nitrous Oxide (laughing gas.) Using this kind of sedation requires no additional training for the dentist. You can leave the office without any residual effects when the procedure is over.

Moderate sedation is referred to as “sedation dentistry.” This allows the patient to respond to questions. They are not asleep.

Deep sedation, or General Anesthesia Dentistry, is often called “Sleep Dentistry” (unconscious). This is generally the recommended level of sedation for individuals unable to tolerate dental treatment for mental or physical reasons. Using this method, there is no memory of the procedure. Dentists who provide this method require a two-year Dental Anesthesiology Residency or an Oral Surgery Residency.
