I'd say all the places I mentioned provide very high quality service but if it were me I think I'd choose the BIDC as it's a large clinic specialized only in dental work.

I usually go to Smile Clinic near the British Embassy for routine stuff like fillings and cleaning but I did have a molar root canal and crown done at the BIDC a couple of months ago. It has state of the art equipment and very highly trained dental surgeons who are specialists in particular areas of dentistry (like implants) ...I certainly have no complaints about the quality of the work they did for me. Remarkably painless, fast and efficient and the crown fits perfectly.
