You know what I was thinking? If a dentist said that to me... you can eat a 1000 cans of tuna etc... I think I'd call the local board of health and report the guy.

Chnaces are excellent he's saying that to other people too, and especially if a pregnant woman comes in, or a mother with a young child, he could very well be endangering their health.

The EPA puts out mercury warnings all the time about fish. That type of advice from a doctor or dentist is completely unethical.
