But my teeth were stained by hard water, can the natural teeth whitening remedies work for me?

As far as I'm aware, natural teeth whitening remedies can work on any type of stains but a lot depends on how badly they're stained. If it's a real problem for you, bleaching might be the best option but I'd advise you to see a dentist rather than trying it yourself as you can do more harm than good with the DIY kits.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
