Dentist Recommendation (Dubai)

I am looking for a recommendation of a great Dentist. I need a couple of crowns, and also like to get tooth whitening done or maybe even some Lumineers?
There are many Dentists here in Dubai, but where to start? I will say that I am not a wealthy Xpat, only been living here 5 months so the cost needs to highly competative!
Thanks for reading.
