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.

My sweet daughter has Autism, and was unable to work with a typical dentist. She must be sedated for dental cleanings, which can be scary for both of us. The team here is always very warm and understanding. They’re patient and willing to help us when she is struggling. Dr. Thoms is so helpful and kind. We’ve seen him for several years now, and I trust him and his team completely. Thank you!
Response from the owner:Thank you for your kind words and trust in our team over the years. We’re so grateful to be part of your family’s care and truly appreciate you taking the time to share your experience. We’ll be sure to pass along your kind words to our team!
I am so impressed with this Place. The staff is super friendly and explains everything in great detail and really takes their time with their patients. I came here after 15+ years of not having Dental insurance or the means to see a Dentist. Needless to say, my teeth were in pretty bad shape, and I needed a deep periodontal cleaning. When I went in for consultation back in February I was totally nervous, anxious had no clue what to expect. I just knew that I needed to a tooth that was falling out pulled and needed to do something about my teeth. After talking with a staff member and Dr. Hoffmann I felt totally at ease. Both my procedures in Feb and May went incredibly well and I woke up from both with an incredible smile. I came back today for follow up and cleaning my Hygienist was awesome I still had some sensitivity around my front teeth and when she noticed I flinched she stopped and said do you need break, or do you want me to put some numbing jell on your front teeth. After we got done, I had a lot of questions about the proper way to floss, what type of tooth paste I should use for sensitive teeth etc and she really took the time to answer all my questions. If you have been putting off dental work because of anxiety, I encourage you to check this place out. The staff truly cares about their clients.
Response from the owner:Thank you for your thoughtful review and kind words. We’re so glad you felt informed, supported, and cared for throughout your visits. Helping patients feel comfortable and confident in their dental care means so much to our team. We truly appreciate your trust!
I went to nervous and 3 to 4 hours later, I essentially woke up in the car on my way home without realizing anything had happened. If you have trauma with previous dental issues, this is the place.
Response from the owner:Thank you for your kind words and for sharing your experience. We’re grateful our team could help provide a comfortable experience and appreciate your trust in us.

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.
