Any good natural whitening toothpastes?

[JPB]

Been try to move towards more natural products lately. One swap-out I've done is my old Crest toothpaste for some Tom's stuff. I like it but my teeth don't seem as white after brushing. I'd like to avoid any non-healthy choices but was wondering if any the more natural toothpastes offer whitening qualities?

Not that I've found, unfortunately.

I've used this one for years, its the best that i've tried so far. I think they've changed the ingredients, but its stillg great. Tom's of maine is horrible and it has some weird aftertaste to it.

I dunno how well the "whitening" works, but I've started using Jason products--including toothpaste.
