I bought this toothpaste for the whitening claims. It does whiten really well, but what I didn't expect was that it would improve the health of my gums! My gums used to bleed when I would floss before I started using this toothpaste. Now they don't! I wouldn't buy any other toothpaste now. It's not cheap, but it's worth it. Some reviewers said they experienced irritation while using it. They might have been using too much. I only use a pea-sized squirt and haven't had any problems.I used to use Crest 3D White and that kept my teeth pretty white. Then, all of a sudden it just stopped working. My teeth looked badly stained no matter what I did. I got the Crest 3D Whitestrips and they made almost no dent. I seriously started to wonder if there was something wrong with me and my teeth. I went to the dentist and asked about their professional whitening services. The hygienist told me to try this toothpaste first (the professional whitening they do in office is like a thousand dollars). It seriously works. After about 1-2 weeks, the deep stains were almost entirely gone. By now, my teeth are pearly white again.I personally like Colgate products. This one actually does what it says. Whitens initially and maintains with use. It works.I like that this toothpaste helps whiten my teeth without making them sensitive like the other toothpastes.It’s exactly as described and not a fake itemBruhh, i bought 1 pack of 2. They sent me 2 bundles. ?Thank you BruhI have only used this a few days and I swear my teeth look whiter. Maybe a little too soon to tell. But what I really love is that after brushing it left my mouth feeling so clean and refreshed. I am so glad I tried this. Highly recommend.I love this tooth pasteWith no tamperseal on both tubes, official red box looked very old and wrinkled like it was soaked in waterAfter using it 3times, I think it caused the long white line across my gums, that, or the vussen by osstem did, this product is not safe and should be removed from sale is my pointLooks like counterfeit product. Do not order! Expiration date is in about two month and the back of the tube looks resealed.
