Was hoping for a bit more drastic whitening on first use but it does whiten at least 2 shades and I will continue to use for the full month but after a week it doesn't seem to be whitening very much beyond this point.

This teeth whitening system is extremely effective. Its like getting them whitened at the dentist. I would highly recommend giving this prodcut a try.

Like the product. Did notice difference but forgot to use on dry toothbrush half the time. Hard habit to break.

Inconvenient to do the tube different tubes separately and also not being able to brush your tongue. I thought it tasted fine.

Great product. Easy to use and the results show! I have been using for three weeks now and my teeth are significantly brighter.

This product will not make a dingy smile dazzling. It is purely for maintaining already white teeth. I have inner enamel issues from fevers as a child... yes, it IS a lovely issue, and I'm always on the prowl for a REAL at home whitening product. This one was OK, but would never do the heavy lifting of whitening.
The taste and texture were just fine though, and it really is very easy to use.

an interesting choice for birchbox, wouldn't have thought it'd be something you'd profile. But nevertheless, i gave it a shot as i do everything i receive from you. i liked this! it actually tasted great, unlike a lot of the over-the-counter whitening toothpastes that are advertised these days. I did actually notice a slight difference after a few days; i'm sure i'll be buying some more soon.

I use this on average of once a week. After about 2 months I did notice my teeth were whiter. If only I can remember to reach for this tooth paste in my hazy mornings my teeth would have been whiter sooner.

I used this product for a full month, day and night, and barely saw a difference. After the month was over, I stated using a whitening mouthwash that made a drastic difference. It's good if you're just looking for a minty toothpaste but not if you are actually wanting to whiten.

I got this product a couple weeks ago and it has been working out great for me since. I have seen a dramatic whitening on my teeth.
