Good product

If you have sensitive teeth, THIS is the product for you. I have the most sensi teeth on the planet, and experienced NO pain or discomfort whatsoever. I'm giving 4 stars since I've not yet seen a dramatic improvement, but I'm going to stick with it, as the process is effortless and pain-free!

I’ve tried many times to whiten my yellow teeth. I have had to stop because the sensitivity is horrible. Just opening your mouth was painful but now…. Wow! No sensitivity at last with teeth whitening. I realize it may take several weeks for my teeth to be really white but am willing to continue with the program because it’s painfree. Yes, my progress is slow but I’ve been a coffee and tea drinker for years so am willing to keep going with the hopes of much whiter teeth.

The Glo Science whitening refill biles product is fairly effective, but I think the cost is a tad high in cost. I look for special promotions before I buy. Other then that, I do like it.

Love the results!!
