Found these guys on the NHS Choices website, where they have decent ratings. I had a good experience — your bang average dentist. I was there at 11am on a Tues and was the only one there. Staff included a female receptionist and a female doctor(though she mightve been just a cleaner/hygenist, she didnt specify). Just had the regular cleaning, for £18. They take credit card. She didn’t try to upsell me into anything that I didn’t need or anything. Even told me that I dont need to come back until 1 year, because my teeth were quite clean.
