What does a physical exam cost?

My Husband just went to a very good Dentist for a NEW PATIENT exam, and spent about $350. This included a full comprehensive exam: Cleaning, gum pocket probing, full set of X-rays, hygeine instruction, Prophylaxis, consultation, diagnosis, etc. My exam as an existing patient cost around $220. It really depends on the quality of dentist you are going to. My Aunt used to work as a hygenist, and told me that the dentists who advertise big specials for $100 new patient exams are usually not the best dentists out there. I figure spending more now with a dentist I trust is better than fixing expensive mistakes that a bad dentist made years before.
