I drink a lot of coffee so my teeth needed something really good but not something to make my teeth sensitive. I heard about HiSmile and beside the fact that I don't have sensitive teeth, I love how my teeth got white again! I highly recommend HiSmile.
Bottom Line: Yes, I would recommend this to a friend
Glad to hear we are able to help out a fellow coffee addict like ourselves!
Keep that smile beaming girl :) Happy HiSmiling.
