I was wondering what's the average cost of a deep cleaning? One dentist told me $300, is this average price or should I look else where? Thanks!

I have to deep cleaning too..I am pretty nervous about it. Anyways my dentist wants to charge me 650 to have my whole mouth done! I am going to shop around because that amount seems like it is way to much. So I would say that 300 is a good price.
