Since the change a few years ago regarding less NHS dentist, I registered with Charles Clifford University Dental Hospital in Sheffield. Wow! best thing I ever did, had treatment every month for almost three years that consisted of deep scaling and polishing a couple of fillings, the work was amazing. I have re-registered again since returning to UK and had my assesment a couple of weeks ago, two and a half hours work, Start treatment friday the 9th Nov. Also registered wifey, she has her asessment 27th Nov. I recommend that if you have a University dental hospital near you, get registered. It helps the students and its all FREE!
