When I started transitioning to raw from vegetarian eating, I found myself detoxing a bit. Changes in my skin, hair, and weight. I think it was overkill because of lack of understanding of the raw food lifestyle. I recommend reading as much as you can on the effects of raw food eating or mistakes made, etc. One link I found that helped was http://www.fredericpatenaude.com/rawsecrets.html.
It talks about some of the common errors in eating the wrong combinations of fruit or too much that can have an effect on your dental health. Health is not automatically cured when you start the diet but can be dramatically improved as a result of balanced raw eating.
