The consultation fees and charges varies from region to region and from doctor to doctor. As such there are no special rules. It's strictly up to the dentist that s/he is charging for what but yes, the patient should be told everything regarding the treatment and for what s/he is being charged for.
Regarding stiches, it is not compulsory to give stiches after tooth extraction. Sutures are generally given when there is laceration but if in case the extraction is simple without much trauma then no sutures are needed. So, dont worry the healing will be fine (prior you take special care of post extraction instructions).
