Review (5/5): best whitening toothpaste I've used
I've been using the optic white toothpaste and whitening pen for just about three weeks now and I have noticed a big difference in whiteness. I even had a couple of family members remark about how much brighter my smile looks now. I cannot use whitening strips because they cause immediate tooth pain when I put them on but this toothpaste and whitening pen combo works very well for me! I will say the pen leaves a little bit of a film but it goes away pretty quickly. I'd say this is the best whitening toothpaste I have ever used.
