Special Needs Dentistry: Can You Be Allergic to Novocaine?

Published:
Updated:

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.

Thanks Laina for making my visit great. You are the best.

Dr. Behl! I cannot recommend Dr. Maris Behl enough. If you have dental anxiety, she is truly the kind of dentist you hope to find. If teeth could be wrapped in pillows and protected by flying unicorns, Dr. Behl would somehow make it happen. I have significant anxiety around dental procedures and have needed deeper sedation for dental work in the past. From the beginning, Dr. Behl took the time to listen to my concerns and made me feel genuinely heard rather than dismissed or rushed. She created such a sense of trust and safety that I was eventually able to have my dental work done with only nitrous instead of full sedation, which is something I honestly didn’t think I would be comfortable doing. During my crown placement, she explained what she was doing throughout the procedure, which made an enormous difference in keeping me calm. She also took the time to address a filling that had been bothering me for what felt like forever — and she actually fixed the problem. What stands out most about Dr. Behl is how safe I feel in her care. She is compassionate, patient, communicative, and incredibly attentive to how her patients are feeling. For someone with dental anxiety, that combination is invaluable. Finding a dentist I trust this much has completely changed my experience with dental care. I am incredibly grateful to Dr. Behl and would recommend her without hesitation, especially to anyone who has dental anxiety or has struggled to feel comfortable receiving dental treatment.
Response from the owner:Thank you for such incredibly kind words! We’ll be sure to pass this along to Dr. Behl. We’re pretty sure the flying unicorns are going to be the part she remembers most! 🦄💙 We’re so glad our team could help make your experience a more comfortable one.
Dr Thoms and his team are phenomenal. No question, the absolute best possible option for my child when he needed work done while sleeping (age based). While this option is not inexpensive, this set up of have anesthesiology in-house allowed us to get his mouth healthy when a traditional pediatric dentist could/would not. I am a parent that asks a lot of questions on behalf of my toddler’s care and at no point did I feel judged for this, nor was I rushed during my evaluation process during the consultation. Although the procedure is not one I would like to repeat for my child, my husband and I were both so pleased with how well Dr. Thoms communicated and how he clearly cared for our son’s wellbeing (both physical and emotional during a less than comfortable visit). Cannot recommend the back of house team more highly. My one detraction is the FOH staff (not everyone) were not nearly as pleasant. I would like to communicate that while their day-to-day is very routine for them, being in that office as a parent is very scary for some people in their office and a little bit of kindness goes along way. I do recall, having a very pleasant conversation with Rebecca, but otherwise everyone else was on the apathetic side, in my personal opinion. That said you’ll notice that I still am leaving a five star review because the dental staff really just knocked out of the park, but as a parent I want to encourage you to look past any rudeness you may experience over email or on the phone because Dr. Thom’s is really that excellent.
Response from the owner:Thank you for taking the time to share such thoughtful feedback. We’re grateful to hear that our team provided compassionate, attentive care and took the time to answer your questions throughout the process. We also appreciate your comments regarding your experience with our front office team and will certainly share your feedback. Your kind words mean so much to us!
Very nice very convenient for me great people working

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.
