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.

Sedation Dentistry St. Louis
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.
If we lived in closer proximity, we would see Dr. Thoms for all of our dentistry needs. As it is, we happily made the 2.25 hour trip three times for my daughter's root canal and crown. Dr. Thoms and the entire team were expert, kind, and compassionate.
We could not ask for more!
Response from the owner:Thank you so much for your kind words and for trusting our team. We truly appreciate you sharing your experience and are grateful for the opportunity to provide care. Wishing you and your family all the best!
Wonderful place for my special needs daughter. She is not always cooperative. They are very good and patient with her. Thankful she can receive anesthesia at the office and not have to take her for out patient service at a hospital. Thank you to all the staff 😇
Response from the owner:Thank you so much for your kind words and 5-star review! We truly appreciate you taking the time to share your experience. Our team is grateful for your trust and is always committed to providing patient-centered, compassionate care.
Best experiences ever. My two special needs children need sedation dentistry and see Dr. Thoms. Dr. Thoms is so kind, caring and reassuring. He truly has a special gift in treating people with special needs. So grateful to be his patients.
Response from the owner:Thank you for your kind feedback. We’re grateful for the opportunity to provide care in a supportive and reassuring environment.

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.
