Seddonendo, Practice Limited to Endodontics


Dr. Bill Seddon

Knowledge and Experience

We had a great time in September at the TDO meeting in San Diego,  3 full on days of education with 6:30 am starts. Here's Dr Seddon speaking at the conference,  the first UK Speaker at the conference since 2006.  A very proud moment.  

After another talk last week in Lincoln, we are now fully back into the swing of clinical practice, armed with new knowledge from the superb meetings.  

Plans are afoot for more events next year, both local and International.  It's something I feel is really important to help keep truly at the leading edge of science.  To be able to teach something well, you have to have a deep understanding of it.  

There's a great blog about teaching here by Richard Feynman

Hopefully in the next photos I post there may be a bit less of me, as I start a fitness drive ahead of a family ski trip next year.  



Now in our New Home on Norfolk Row, in the heart of Sheffield

Our Mission is simple: to provide you with the finest endodontic treatment available anywhere.

We offer emergency treatment in Sheffield for toothache, and aim to treat referred cases within one week, and emergency cases on the same day.

We are always told we have the most comfortable chair by our patients. Every week we have patient's drop off to sleep while we work.  

Mr Seddon has recenly become the only UK Dentist to be awarded Fellowship of the International Academy Of Endodontics. He was presented with his certificate at the Annual meeting in Scottsdale in June. He is greatly honoured and thrilled to have received this recognition by his peers and mentors.

Membership in this Academy, exclusive of its founding members, shall be by invitation only and be awarded to individuals who have been vetted and earned peer recognition for their endodontic achievements in clinical practice, research or education. 

Our "make no compromises" philosophy places our practice in the top tier of endodontic practices, nationwide. Our "quality first" emphasis has helped many other endodontic practices reach beyond their potential.




Endodontics in the heart of Sheffield

Utilising the latest technologies to enhance patient care, we provide referral based endodontics for dentists throughout the UK.  We work with many specialists and Implant experts also. 

Our bespoke treatment room is equipped specifically with microscopic based endodontics in mind, we also use it when teaching other dentists. 

5 minutes from the train station with discounted parking adjacent in Q-Park Charles Street, it's simple to access the practice.  Our new location puts us in sight of the iconic Crucible Theatre.  

Practice Profile

Our office is committed to treating you with respect and providing valuable care in a friendly and comfortable environment. We are committed to educating you about endodontics and assisting you in making appropriate treatment decisions. 

We provide high quality endodontic treatment with the aid of the most advanced technology available in the field of endodontics:

  • State-of-the-art Global Surgical Operating Microscope which offers increased magnification and illumination to visualise complex root canal anatomy and allows for conservative treatment (preservation of tooth structure). Live feed to a 50 inch flatscreen monitor for teaching purposes. 
  • We use digital radiography which reduces the amount of radiation exposure to our patients compared to conventional film and increases our diagnostic capabilities.
  • Our practice uses a paperless record keeping system, The Digital Office (TDO). TDO is a secure, GDPR compliant, practice management software that is tailored to the specific needs of specialist endodontists. Online registration is a time-saving advantage for our patients, providing our patients and referring dentists the ability to view and update their information online at their convenience. If you have any questions, feel free to contact our office for more details and instructions about this process.

Patient and Dentist Testimonials,

I am THE most nervous of dental patients having had an unpleasant experience many years ago (not with Mr Seddons may I just add), so was in quite a state when I was told I needed root canal treatment. In fact it took me 2 weeks to pluck up the courage to call in to make the appointment! However, from the moment I first placed that call to the Seddonendo team, my fears were managed with empathy and understanding. My whole expereince from start to finish has been exceptional and I cannot recommend Mr Seddon and his lovely wife Jaana highly enough. I literally did not experience one second of discomfort and the care I have received has been without doubt more than I could ever have imagined or wished for. I am very happy to speak to other nervous patients if this would in any way help with their fears and get them the very best in root canal treatment. Thank you from the bottom of my heart for my overall experience. I would never be fearful of this again.

Today's root canal treatment

As a Dental profesional I had the pleasure of observing Dr Bill Seddon work and I have to admit that it was the best skills that I had ever come across to see combined with most comfortable environment for patient. Thank you so much for letting me see your work, much appreciated.


Bill and Jaana did a great job of my root canal work. it was quick and painless and I haven't had a twinge since. Unlike the first and more local point of referral, they were able to treat me the next day, rather the after 4 weeks offered elswhere.
