Dr. Bill Seddon

At Seddonendo, we help you save your teeth and relieve pain with expert root canal treatment in Sheffield. Using the latest technology, our caring team makes sure you’re comfortable every step of the way. Whether you’re dealing with tooth pain or need urgent care, we’re here to help you smile again. 

We’re back from an amazing meeting in San Diego, and we’ve come home with lots of new ideas to improve the care we provide. Some changes are already in place, and more are coming over the next few months! We even had time to watch a baseball game for the first time, though rugby league is still our favourite!

In March, we also had a fantastic time catching up with old friends and making new ones at the International Academy of Endodontics meeting in Orlando. Now that we’re back in Sheffield full time, we’re thrilled to offer emergency appointments up to 4 days a week to help those in urgent need.

Dr. Seddon recently spoke at a conference in Scotland and is honored to be organizing the International Academy of Endodontics meeting in Manchester in 2025—the first time it’s being held outside the US! He’s also continuing his professional development by attending conferences like the Langham Endodontic Study Group in London.

We’re thrilled to offer advanced diagnostic services with our Carestream 8100 Cone Beam Scanner at our Sheffield practice. Dr. Seddon has been using Cone Beam CT (CBCT) technology for over 12 years to get clear, 3D images of your teeth and jaws. This technology is especially helpful for complex cases, like retreatments or when diagnosing tricky dental issues.

The scanner is fully integrated with our other imaging systems, meaning we can quickly and accurately identify problems and provide you with the best possible treatment. Dr. Seddon is also fully qualified to provide detailed reports on the scans, ensuring you get the most precise diagnosis.

in 2018, Dr. Seddon had the pleasure of teaching hands-on courses to over 250 Dentists in 3 cities in Saudi Arabia. Sharing his knowledge and experience in other places like Singapore, Dubai, and Abu Dhabi has been a rewarding experience, helping dentists refine their skills in endodontics.

In February 2022, Dr. and Mrs. Seddon also attended the Bioclear Summit in Arizona, where they met with leading restorative and cosmetic dentists. The goal? To continue offering our patients the best restorative options after endodontic therapy. We came back with great ideas, and we are now using these routinely to improve our patient communication. Artificial Intelligence is close on our radar, and is being used daily.

At Seddonendo, our mission is simple: To provide the best endodontic treatment available.

We offer emergency care for toothache, aiming to treat referrals within a week and urgent cases on the same day. Many of our patients even find our chairs so comfortable that they fall asleep during treatment!

Dr. Seddon is the only UK dentist to have been awarded a Fellowship from the International Academy of Endodontics, a recognition given to dentists who excel in clinical practice, research, or education. We are proud of this achievement and grateful for the trust our patients place in us.

We believe in a “no compromises” philosophy, focusing on quality first. This approach places us among the top endodontic practices in the country, and it’s our commitment to ensure you receive the best care every time you visit.

At our Sheffield practice, we provide advanced root canal treatments for patients referred by dentists from all over the UK. We also collaborate with many other specialists and implant experts to ensure you receive the best care possible.

Our custom-designed treatment room is equipped with the latest technology, including a microscope specifically for precision root canal treatments. We also use this space to teach other dentists how to perform these advanced procedures.

Conveniently located just 5 minutes from the train station, with discounted parking available at Q-Park Charles Street, it’s easy to visit our practice. You’ll even find us near the famous Crucible Theatre!

At our office, we’re dedicated to treating you with respect and providing excellent care in a warm, comfortable environment. We believe in helping you understand your treatment options so you can make informed decisions about your dental health.

We offer high-quality root canal treatments using the latest technology to ensure the best possible results:

    •    Advanced Microscope: Our state-of-the-art Global Surgical Operating Microscope allows us to see even the tiniest details inside your tooth, helping us preserve as much of your natural tooth as possible. We also use a live feed to a large screen for teaching purposes.

    •    Safe and Accurate Scans: We use digital X-rays and a Cone Beam Scanner, which lowers radiation exposure compared to traditional methods. The CBCT Scanner also gives us 3D images of your teeth, allowing us to better diagnose and treat complex cases.

    •    Paperless System: Our practice uses a secure, GDPR-compliant paperless system called TDO. This software makes it easy for you to register online, update your information, and view your records at any time. It also helps our team stay organized and focused on your care.
