Bests & Worsts Reviews from Amazon

~ ~ UPDATED AFTER 4 DAYS OF USE: I have used this 3D White toothpaste for 4 days in a row and also did some research. PLEASE USE THIS PASTE WITH CAUTION. I have found the Journal of Clinical Dentistry and L.A. Times have done a clinical study (in 2011) on the abrasiveness of this 3D White toothpaste along with 25 other name brand whitening toothpaste (google 'The Healthy Skeptic Whitening toothpastes a bright idea?' for the article) The study have found that this 3D White toothpaste has a RDA (Relative Dentin Abrasion) of above 200 which is considered to be 'potentially damaging to dentin' (dentin is the layer beneath your enamel). Normal regular toothpaste has RDA of well below 100. My advice is to use this toothpaste for about a few days (like I have) and then only use it every 2 days interval or perhaps only use 3D White on special occasions. All other times, use a regular toothpaste with ADA (American Dental Association) seal. I would also like to note that this 3D White toothpaste does NOT have any bleaching effects like the white strips do since the toothpaste only use the 'abrasives' to 'polish' out the stains. Again, please use it with caution and avoid using it 24/7. I wanted to share this review since I think many like me is worry about this kind of stuff. Once you have damage to your enamel or dentin, you will never get them back! thank you for reading. if you felt this review is helpful, it would be nice have comments below. :) --------------------------------------------------------- I have yellow tinted teeth and am neither a smoker or coffee drinker. I had gotten some minor stains from the Crest Alcohol-free mouthwash but that's a different story. So I got this 3D White toothpaste. This toothpaste really works in whitening! Well so far, I have just finished 1 brushing, and my teeth got noticeably whiter and a little bit shinier (may due to the polishing ingredient- see label on the box). I have read some reviews saying that this may cause gum sensitivities and it indeed did to me but in a very very minor extent. Before using this toothpaste, I used the Crest Hydrogen Peroxide and Baking Soda toothpaste which has the 'burn feeling' a lot more than this 3D White toothpaste. The cap is very flimsy as mentioned in other reviews. I will update this when I use this more.
