i smoke and drink a lot of coffee so my teeth were pretty stained so i used a magic eraser. i just tear off a corner and use that works great everytime. i do this often, about once a month, and when i went to the dentist i asked her if she thought my teeth looked dammaged and she said they looked great so i dont think it will hurt to keep using it. give it a try.
I Have used it and works great!
