After spending the money for both the hygienist and the whitening... I left with the exact same shade.
After calling to discuss, I was met with a very rude man who told me I “should have paid for the £400 session instead” and that it was my own fault.
Dr Sia was lovely and knowledgeable, but I suggest renaming the procedure to “polishing” as there is in no way any whitening.
Had such a wonderful experience - I felt completely at ease even though going to the dentist’s has always made me nervous. When there was some sensitivity, Dr Asia provided a numbing cream and it went away completely. At all times I felt like I was in control and in safe hands.
