Well its not that cut and dry as ppl make it seem. I talked to an OMFS and they said that making more means that the tax bracket is raised and the proportion u pay is much more then a GP (in general). Another thing is that the income of GPs is pretty variable. Dentistry isnt just a health care profession, its a business where making specific decisions save tons of money. In the city of duluth, there is a GP whose gross annual income ~750,000 because he own his practice and has a few dentists work there with him and knows a thing or 2 about business
