Instead of specifying a Western Dentist, do a search for a dentist who has received their Dental Degree from a Western University.  There used to be a Jordanian (by birth) dentist at Family Dental Centre near C Ring who studied at Marquette University in the US.  She was very good (she left and I don't know if she has returned or not, but I believe her brother is or was with that practice).

Western dentists don't guarantee good care or honesty.  I've heard of quite a few who not only grossly overcharged some patients but actually hurt them in the process.
