And alternative to floride toothpaste.
Color: A - Magic Mint (Pack of 1)
I've been using this alternative toothpaste for a couple months now. It's expensive compared to regular toothpaste, but some suggest that it's healthier for your teeth. Nano hydroxyapatite is supposedly the same molecule that our teeth are made of. So perhaps it may be better for hardening teeth than fluoride. Of course, I can tell if it is doing that or not. Do your own research.
It's a bit more fluid than standard paste, so it sits more flat on the toothbrush. I've discovered that if it dribbles from your mouth onto your shirt, it leaves a white stain on the fabric! So don't use it while wearing your good work shirt. The taste is more mild than the usual minty toothpaste. Not bad at all. At my next dental exam we'll see if it's cleaning my teeth effectively.

I love this toothpaste
Color: A - Magic Mint (Pack of 2)
I love this toothpaste, this is my second time buying this and it cleans very well and the whitening does really work I’ve had many complements on how clean my teeth look and how white they are. The packaging is nice, the ingredients are simple and the texture is very smooth and doesn’t foam too much . Definitely recommend getting

A wonderful tradition for our family
Format: Calendar
I'm surely hoping that the scuttlebutt saying that this will be the last years old Farmers almanac isn't true! This is the most delightful calendar, and I get one for myself and my daughter every year. But this year I couldn't find it at my normal bookstore, so I went to trusty Amazon.
It is so full of beautiful illustrations and interesting facts that I almost hate to turn to the next month
