Root Canals (Endodontics)

Dentist in Creve Coeur, MO

If you have an infected tooth or a nerve in your tooth is in pain, then you may need a root canal. Root canals are an important procedure to save badly damaged or infected teeth. Thankfully due to modern advancements, root canal treatments are relatively simple and painless procedures.  

A root canal is a procedure where the canals within the teeth are disinfected and sealed off so that bacteria cannot continue to thrive. When a tooth becomes infected the only way to get rid of the infection is to do a root canal or remove the tooth all together. If you have an infected tooth or a nerve in your tooth is in pain, then you may need a root canal.

How Root Canals Work

Each tooth has one or multiple canals that run from the tip of each root to a cave like structure (called the pulp chamber) in the center of the tooth. Because these canals are so thin a very limited amount of infection fighting blood cells can reach this area. When a tooth becomes infected, it is this limited blood supply that prevents our bodies from being able to fight off the infection completely. Even modern antibiotics will not completely remove a dental infection.

Root Canals (Endodontics)

Persistent tooth pain, sensitivity to hot or cold, or swelling around a tooth can make everyday activities uncomfortable. When these symptoms occur, an examination can help determine whether root canal treatment may be needed to preserve the natural tooth. At Creve Coeur Family & Sedation Dentistry in Creve Coeur, MO, our team evaluates these concerns and discusses appropriate treatment options. If you’re experiencing symptoms of a possible dental infection, contact our office to arrange an evaluation.

Once the center of the tooth and root canals are disinfected from top to bottom, these areas are then filled and sealed so that no bacteria can fester. Now that the tooth is properly sealed the body can fight off the remaining infection outside of the tooth’s root.

The only alternative to treat a dental infection is to remove the tooth altogether. While this may be necessary if the tooth is severely compromised, no restoration is as good as a natural tooth.

Symptoms of dental infections can be very similar to those of other dental problems. Luckily, our team of experts can help distinguish these symptoms and properly determine if a root canal is truly needed. Please contact us about whether or not you should get a root canal treatment.

We use very modern techniques that ensure a faster and better quality root canal treatment.  Also, just like all procedures we provide, we will make sure you have a good experience!

FAQs

1. What is a root canal?
A root canal is a procedure that removes infection from inside a tooth. We clean and seal the canals to stop bacteria from spreading. This treatment saves your natural tooth, relieves pain, and helps avoid the need for extraction.

2. Do root canals hurt?
Modern root canals are virtually painless. With today’s anesthetics and techniques, most patients feel little to no discomfort during treatment. Many even compare it to getting a filling. Our team ensures your comfort every step of the way.

3. How do I know if I need a root canal?
Signs include severe tooth pain, sensitivity to hot or cold, swelling, or a darkened tooth. Sometimes there are no obvious symptoms. A dental exam and X-ray are the best ways to determine if a root canal is needed.

4. How long does a root canal take?
Most root canals can be completed in one visit lasting one to two hours, depending on the tooth and extent of infection. In some cases, a second appointment may be needed to complete treatment and place a crown for protection.

5. What happens after a root canal?
After treatment, your tooth may feel slightly sensitive for a few days, but this quickly improves. A crown is often recommended to restore strength and prevent further damage. With proper care, a root canal-treated tooth can last a lifetime.

We feel like family here. Shanna and Dana are so helpful getting us in with our busy schedules and helpful with our insurance. My oldest had a bad experience with a pediatric dentist when he was younger and he's so comfortable with Sabrina. My younger son has some sensory preferences and Mary is so good with him. Even Sarah, the practice manager came to check in with us. Dr. Kratz is so thorough and works well with our orthodontist. I highly recommend this practice.

I was a bit apprehensive since it had been an extremely long time since I visited a dentist. They put me totally at ease. They didn't chastise me, though I surely had a lot of tartar on my teeth. However, I didn't have any cavities. They didn't try to get me to do any additional work. They did tell me about a bite guard, but they didn't pressure me to get one at all. They didn't make me regret going to the dentist. They made me glad I did.

I had a referral from a friend who loves this dental practice. This was my first visit and it was great. Setting up all my information on the website before I even got there was a breeze, and saved a lot of time when I arrived. I was greeted by Shanna who was extremely friendly and helpful as she was on the phone trying to find me a good appointment time. Everything ran right on time so there was no waiting. My hygienist Sabrina was also very friendly and thorough, and careful not to hurt me. She also explained exactly what she was doing at each step. When Dr Kratz came in, he too was very personable, checked everything very carefully and explained everything to me. My entire experience was great and worthy of more than 5 stars if I could give them. My thanks to Dr Kratz and the entire staff.

Brandon and his team (Mary dental hygienist) are totally awesome. They are so through and explain every process of what they are doing before they start putting things in your mouth and working. I have clean teeth and feel well educated about problem areas in my mouth. Super professional. Everyone I met was friendly and seemed to put people and patients first. Can’t say enough good things. This has contrasted every single other unpleasant dentist experience I’ve had as an adult.

I can’t say enough great things about Creve Coeur Family & Sedation Dentistry. From the moment we walked in, Sarah at the front desk was incredibly friendly and a clear communicator—she made sure everything was seamless and that every step was understood. She also took extra care to ensure my elderly mother was comfortable, could hear the information clearly, and fully understood what was happening. Dr. Kratz was excellent as well. He explained the work that needed to be done with clear pros and cons, so we felt informed and confident in the plan. He was also able to fit my mother for a partial the same day, and the follow-up process is already underway to make sure it’s a perfect fit. On top of that, he’s genuinely funny—which helped put my mom at ease during what was an emergency appointment. Sabrina, the hygienist, did a wonderful job measuring my mom’s gums and cleaning her teeth. She spoke loudly and clearly so my mother could hear and follow everything, and my mom did not experience any pain. Kinanie helped with the partial mold and was incredibly friendly and skilled. We truly felt like everyone cared—not just about getting the job done, but about making my mother feel safe and comfortable. This appointment meant even more because my mother had been mistreated by other dentists who didn’t understand how chemo was affecting the bone of her jaw. At Creve Coeur Family & Sedation Dentistry, we finally felt respected, understood, and in the hands of a team that knew how to care for her properly. Highly recommend—this is the kind of care everyone deserves.

I would like to take this opportunity to compliment Creve Coeur Family and Sedation Dentistry Dr. Kratz and Staff. Dr Kratz has built an amazing staff that exhibit professionalism and personal care and empathy for their clients. I would especially like to mention three staff members :Sarah, Shanna and Kinanie and of course Dr Kratz.. they have walked me through a dental procedure with excellent before and after care which made this experience easy-whether it be expert immediate appointments (Sarah), expert aftercare (Kinani) or Financial Knowledge and scheduling (Shanna) all my needs have been met as if I was a Family member!! Well done Dr Kratz in building such a Team!!

The whole office has a good vibe! The manager, Sarah is friendly, inviting and knowledgeable. I felt really comfortable with Rachel, the dental assistant, in the sane way. I already had xrays from a previous dental office but Rachel took actual pictures of my teeth in addition. No office has ever done that for me. I feel like this office is more thorough and takes the extra step and effort. Dr. Kratz, the dentist, was just as wonderful, too. I felt at ease with him and he made me feel we were on the same level. He was honest and friendly and really took the time to examine and talk about my teeth. I am switching to this dental office starting today. The atmosphere at this office is warm and comforting. Thank you for a great experience! I look forward to my next appointment with them.

Had to get a crown at 8am this morning. I can say, without a doubt, that every single 5 star review is well deserved. Dr. Kratz is seriously just that good. His assistants (especially Kinanie who was with me this morning), are just that good. They know exactly what they’re doing. I truly appreciated how they walked me through the entire process. I even got to see my crown being created - how cool is that?! The vibes are comfortable and relaxed. The office is filled with laughter. Not something you’d expect at the dentist, but that’s how it is here. If you like efficiency and dentists who actually know what they’re doing, this is the place to go. No doubt.

I’ll start by saying I do NOT like going to the dentist. I barely slept the night before my first appointment because I was literally so nervous. Turns out, I should’ve slept like a baby. From the moment I scheduled my appointment, every single staff member was incredibly kind. They truly went out of their way to make the whole experience feel relaxed instead of stressful. Rachel was especially wonderful - friendly, reassuring, and never once made me feel embarrassed/judged about my teeth. Dr. Kratz also takes the time to explain everything thoroughly, so I always knew exactly what was going on and what the plan was. Nothing ever felt rushed or confusing. Genuinely cannot recommend them enough. Absolutely worth the drive no matter where you live.
