I've been a patient for over ten years. The main reason I like Confidental is they will always see me ASAP if I have bad toothache.
They are very professional and make sure they reserve sufficient time for treatment. i.e. no rushing to get the job done. A consequence of that is they are not the very cheapest but they are not extortionate either. I would say they charge just the right amount to ensure they can provide a service of the highest standard.
They are all very good dentists there trained at King's College London. I would say S is slightly more personable and D very professional and competent. V is in between. They also have a female dentist B who IMO is excellent at putting patients at their ease. Frankly though, they are all very good, well trained and know what they are doing.
Oh and lets not forget the receptionists. Since quite a few people including myself, are quite scared of dentists, its the receptionists who you have first contact with and they are very important at putting you at ease. If you have a really bad toothache, they understand and will do everything they can to get you seen ASAP. A real credit to the practice.
All in all highly recommended.
