Hi everyone
I have a teeth bleaching kit in my fridge which does a great job on whitening my teeth - but I'm quite sure that it's a disgusting thing to do to my body because of the harsh chemicals, especially as I always feel really super-sensitive throughout my whole body for 24 hours after using it.

Does anyone have any great tips for getting really white teeth, healthily???
Also, as I'm my hair is going a bit grey in places, I've been having a soft semi-permanent hair colour for some time...but I'm sure that's not good for my body either. Any recommendations gratefuly received!!! Thanks.
