can a dental health website make money?

[Awesme Forsome]

My friend who is a dentist wants to make a dental health website,which will be composed of articles about dental health awareness, example "how to maintain oral hygiene" or "bleeding gums management".These articles will be written in simple non technical language,which is intended for general public.Can he make money from this kind of website?if yes, please mention how...i mean through adsense, or affiliate marketing or CPA networks? In future he will progress towards adding more features and widgets to the website.Kindly answer.Thanks.
