At first I thought 'eh, it's a little steep but I could still see it depending on part of the country'. Then I realized you were talking about a child and not dh as I originally thought it said. That seems awfully steep. How old is he? I would definitely get a 2nd opinion, especially where children's teeth are concerned as there may be less expensive alternatives that are just as viable. That's just my 2cents (and I worked in a dental office for 10 years).
