Great for Sensitive Teeth
It is a gradual whiten like all whiteners, so you will obviously need to wait a bit to see results but from trying it out I can tell it is made for sensitive teeth like mine and the gum oil I think does help soften the harshness even more. This product was also sold at a reasonable price even during Christmas.
Anyway, I was honestly just too lazy to put my review here but it is an honest review that I felt like I can spare a few mins to write. I mean I HAVE to review since they're not only great for sensitive teeth but the fact that they sent me a full sized tube of toothpaste months later. It kind of feels like they're thinking of me in a way. This is a whole other world of best customer care I've received. Honestly did not know about it as the email was in spam. I'm probably going to come back when I feel like another dental purchase!
