How long does it last? I have got it since June 2016 and it does not seem to fall away. No matter how often I brush my teeth. Unfortunately, I have not visited my dentist or dental hygienist since I got the stone but I believe it will not make any difference.
And how to remove it? I have done it myself but if you are afraid to do it yourself, you can visit your dentist.
What was the price? I paid around 35 USD in Prague including the stone.
Next week I will try the stone on my eyelashes … So, wait for the next blog post ;).
