How Long Will the Effects of Novocaine Last?

Published:
Updated:

Novocaine is a local anesthetic that is generally used in dental treatments or small surgeries.

It is ideal for this type of procedure because it has a short-lived effect and can be concentrated in small areas. Depending on how the practitioner uses it, its effect will typically last between 30 and 90 minutes.

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.
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.

Searching for a new dental clinic is challenging for someone who has dental anxiety, fear, and traumatic experiences in a dental chair. The staff and doctors at the Dental Anesthesia Center were immediately very welcoming. Dr. Thoms put together a very detailed plan to repair and replace the previous work that I had in the past that was now causing problems. Putting my faith in him was the best thing that I could have done for my situation. I am more than completely satisfied with all of the extensive dental work that I’ve had with Dr.Thoms. I had my fourth sleep dentistry experience yesterday and I’m very happy with my results. I highly recommend this practice and truly want to give them more than five stars! Thank you for giving me back my health and confidence. I adding to this post because of my visit today with the best dental hygienist Delaina and my exam with Dr. Biehl. I have truly never been to such a caring and supportive dental group. Everyone is always conscientious of my needs and knows that I have issues with anxiety. I am always calm when I am sitting in the chair because of their kindness. I am so pleased with the Dental anesthesia center. There needs to be more than five stars. Thank you, everyone.
Response from the owner:We know it isn’t always easy to find a dental office where you feel at ease, so your words mean the world to us. We’re so glad you feel comfortable with our team and truly appreciate your trust and recommendation!

If you are about to have a procedure with Novocaine, here is what to expect.

What is Novocaine?

Novocaine is a brand of the local anesthetic procaine, usually used for uncomplicated procedures. It numbs a small localized area, allowing the doctor to perform surgery.

The types of procedures that require the use of Novocaine vary from dental care to small surgery, such as dermatology, ophthalmology, etc. Your doctor will most probably administer this anesthetic when treating a cavity, removing a wart, or collecting tissue for biopsy.

A Short History of Novocaine

Novocaine revolutionized the medical world at the beginning of the 20th century, becoming the first synthetic local anesthetic to be used in the United States. It has allowed doctors to perfect their procedures and increase the quality of treatment received by the patients.

Novocaine replaced cocaine as the local anesthetic, and it had fewer side effects than the drug. In the last decade, with new synthetic anesthesia being introduced, Novocaine lost its popularity, but plenty of dentists and doctors continue to use it.

How Long Do the Effects of Novocaine Last?

If you are worried that Novocaine will not numb you throughout your procedure, it is important to note that while it might be the shortest-acting local anesthetic nowadays, your dentist can make it last longer by administering it together with epinephrine (adrenaline).

The dentist will increase the dosage if needed or switch to a different drug in case Novocaine is no longer helping.

Novocaine by itself will typically last about 30 minutes, while paired with epinephrine, it can last up to 90 minutes. Its effects begin 9-10 minutes after being administered through an injection in the tissue.

What Factors Could Influence How Long Novocaine Lasts?

The main factor that dictates how long the drug’s effect will last is the dosage. Your sedation dentist will calculate the dosage based on the size of the area that needs to be numbed, the number of nerves present in that area, and whether epinephrine will be used.

If the Novocaine injection doesn’t seem to work, the dosage will be increased, or the injection will be made in a different area. The doctor might also choose to use something else.

The bottom line is this: Novocaine is a widely used local anesthetic because it is generally stable and safe for patients. Its prolonged effects, when paired with epinephrine, allow it to be used for a broad range of treatments while having minimal side effects.
