I basically paid $1500 for a mouth piece I used for a week and about an hour and a half of his expert opinion. He wanted another $8300 for a tooth extraction, one implant, and two crowns. That's almost $10,000 for the math challenged. ;-) I think he's probably very good at making quality crowns (based on the splint he made me), but I never used him for extraction/implant surgery because he was twice as expensive as the other oral surgeons I was considering and he said if there were any complications with the extraction/implant surgeries, he'd refer me to an oral surgeon... so I just decided to use an oral surgeon from the get go.
