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.

Friendly staff, treat you like family! Been going for 30 years. Love this office.
I have some of the worst anxiety when it comes to anything dental/dentist and after meeting Dr.Thoms and his awesome crew they assured me all would be easy and smooth. You will have to get thru your own fears leading up to the appointment but once you do and you’re in their care before you know it, it’s time to leave. I hope Thoms had another 20-25 years in him because that’s my go to guy from here on out!
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.
I highly recommend the Dental Anesthesia Center. The best dental care, knowledgeable, efficient, state of the art facilities, friendly, painless, AWESOME! Laina is my hygienist and she is very thorough!! Dr Hoffmann has always done my dental work and he is truly amazing, I never feel a thing!
Response from the owner:Ann, Thank you so much for your kind review! I'm glad to hear that you have had such a pleasant experience! The Dental Anesthesia Center

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.
