Seddonendo, Practice Limited to Endodontics


Dr. Bill Seddon

Coronavirus Statement

Following statements from the CDO's of Wales and Scotland, and it can only be a short time until England do the same, that any aerosol generating procedure in general practice is outlawed.  Regional centres will open for treatment of emergency cases and I have offered to help out in those centres, but my private practice will be closed for anything other than advice. 

Here's an interview I did on 29 March re the situation,

Latest from the BDA is pretty clear, and likely to develop further.  We shall offer a telephone advice service and of course will communicate via email. We follow all published guidelines from the Department of Health, as well as adding our own extra precautions.  Our role is that of providing an urgent and essential service. There is now specific guidance from The British Endodontic Society as to what we should be doing, and we will follow this guidance. 

I will keep my Facebook business page updated as well as providing info on here at


Abu Dhabi 3 day course
Knowledge and experience

Welcome to Seddonendo.  We are now fully back into clinical work after the lecture tours to Singapore, Abu Dhabi and Dubai.   Please browse around the site to see how we can help you either as a patient or a referring dentist.  

Dr Seddon is pleased to have worked with in Singapore, Abu Dhabi and Dubai over a couple of weeks in February 2020.  It's been a very busy time getting ready for these trips, but worth it as I met some lovely people, and helped teach hands on courses to over 60 dentists from many different cultures.


Endodontics 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,

What can i say.. If Carlsberg did dental surgeons! When you hear you need root canal work you hear the horror stories you hear the pain and trauma people have gone through all i can say is they didnt go to this man. Professional , calming and informative. You are at ease during the treatment wit reassuring words from him and his nurse.If you like skiing hes good at that too ! thank you so much i cant recommend you enough

Jane Currie

Just a quick update so sorry i dint realise the lovely nurse was your wife ! What an amazing team you are

Jane Currie

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.
