flouride substitutes

[midnightrider]

I have had numerous cavities and a chipped tooth over the last few years, so I have a good bit of enamel in my mouth. What I am wondering is: Is it safe to use a toothpaste without fluoride? I'll take it a step further and ask if it is safe to use a fluoride-free and sodium lauryl sulfate-free toothpaste?

I've considered trying childrens toothpaste or an organic toothpaste.

Also, I've tried baking soda, and after some research... I will never use it again as a permanent toothpaste.
