You may not be able to use Novocaine, or you may need an adjustment in dosage or monitoring during your dental treatment.

Sedation Dentist in St. Louis

When it comes to sedation dentistry, the most common form that all dentists use is local anesthesia. Novocaine has been in use for a number of decades and, most of the time, doesn’t cause any problems. However, as with any type of medication, there is always the potential for side effects.

We brought our 1.5 and 3.5 year old daughters here for cleaning / check ups. Our dental hygienist Laina was amazing...made them feel so comfortable. They had a great time and keep asking when they can go to the dentist again. Dr. Hoffman was great too and made everything super quick and not stressful. Great place for kids in addition to adults!
Every person in the office is so personable. That first off makes you comfortable. But then the methods used to clean my teeth, particularly. I don't feel a thing, and it's the first time in my life that I haven't. And I have a lot of anxiety about dental work, and I really do not feel a thing when my teeth are being cleaned
I came here with my 18 year old daughter who has an immense fear of Doctors and Dentist , The kindness and understanding without any judgement we received from Dr.Thom was just unbelievable. The work he did on my daughter was life changing for her . I would recommend him to anyone . Just amazing, kind talented Doctor.
Response from the owner:Thank you so much for your heartfelt words! It means a great deal to our team to know that you felt welcomed, understood, and cared for. We’re especially grateful you shared how meaningful your experience was.
We met Dr. Shawn in Sept 2023 and in December, he removed our adult nonverbal son's wisdom teeth. Not gonna hold you, general anesthesia is billed incrementally (by the minute/quarter-hour) and is a heavy financial investment. I love this clinic because it really is a safe space for special needs families. There's a huge calm that accompanies knowing your dependent person is getting healthy. Dr. Shawn is exceptional. We drove 6 hours to get here so we'll choose a local practice for routine sedation cleanings down the road. I hope to see more neurodivergent acceptance built locally in our state's dentistry like this team has here. Meanwhile we are so grateful for this practice and grateful our son was in Dr. Shawn's care.
Response from the owner:Thank you so much for sharing your heartfelt words. We’re honored to be a place where families feel safe, supported, and understood. Your trust in Dr. Thoms and our team truly means so much to us.
Dr. Thoms and Robin are excellent in their care, concern, and support. Dr. Thoms explains everything and takes his time. If I have questions or concerns, he is easy to talk to and listens well.Robin is right there by my side throughout procedures. Her technical skills and professionalism are impressive. She is terrific!
Response from the owner:Thank you for your kind words! We’re so glad Dr. Thoms and Robin made you feel heard, supported, and cared for. We’ll be sure to share your wonderful compliments with them—they’ll mean so much!

People who are sensitive to Novocaine may experience an allergic reaction. If you’ve used it before and it hasn’t caused any issues, then you will likely not suffer an allergic reaction. However, if it is your first time, let your dentist know so that he or she can monitor you for any symptoms.

A Decrease in Novocaine Use

Anesthesia was first used in the 1800s, and the practice has continued to progress substantially over the past two hundred years. When Novocaine was first introduced, dentists used it to inject into the sensitive parts of the mouth so that patients wouldn’t feel any pain. Over time, the number of people having an adverse reaction began to grow, which has led many in the dentistry field to try to find an alternative.

Articaine

Although not used frequently, studies show that Articaine is not only a viable solution for those with Novocaine sensitivity or allergies, but it might be a better product overall. Articaine is a medicine that can be an excellent alternative to injectable Novocaine. It is the most widely used local anesthetic in many European countries.

Lidocaine

Lidocaine is a medication that has been used in both the medical and dental industries for a long time. Like Novocaine, it is an injectable substance that is meant to numb the nerves and gum tissue in the mouth to make dental procedures far less painful.

Lidocaine remains the standard of care when dentists are looking for local anesthesia options. The advantages of using Lidocaine versus Novocaine are that there are fewer side effects and that Lidocaine has had a proven track record for the last 50 years.

Allergic Reactions to Novocaine

Allergic reactions to Novocaine can range in severity. The signs and symptoms of an allergic reaction are typically limited to the area of the mouth where it is applied and may consist of swelling. In rare but severe cases, a person may experience a drop in blood pressure or difficulty breathing.
