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 patients 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.

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:

Patient and Dentist Testimonials,

Dear Jaana and Bill,

Thank you so much for everything. My whole experience with you both was honestly amazing, starting with Jaana’s initial phone call which made me feel completely confident in going ahead with my treatment right the way through to the treatment itself, she was so caring and lovely. I had no real idea about the treatment itself, only horror stories from years before so I decided the head in sand approach was best. I was a little concerned about pain but that was mostly because I had a long drive afterwards, but you were both right, there was a absolutely no pain! It was even tempting to fall asleep during the procedure as it’s rare for me to spend an hour or so with nothing to do! I was worried about what it would be like once the anesthetic wore off but there was nothing, no pain at all and it’s the same this morning.
Today I am all smiley with my newly levelled tooth and am so glad that it’s all fixed and behind me, my next move is for nice unstained teeth to undo years of peaty Scottish water and I promise to never neglect my teeth again!
Thank you both hugely,
Whole experience honestly amazing

Dear Bill 


Thank you very much indeed to you and your excellent dental nurse/wife for my recent root canal filling. It was pain free by the end of the next day and looks an expert, neat job. The process was unbelievably comfortable and reassuring. It was good to have the short updates of how the procedure was going and what you were doing.

Unbelievably comfortable and reassuring


I Just wanted to say a big thank you to everyone for making me feel safe on my visit, and an extra big thankyou to Bill for the excellent job he has done on my tooth. Although i was prepared with boxes of paracetemols and ibuprofen, I had absolutely no pain after the procedure, 


Excellent job, absolutely no pain

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
