Colgate Optic White Pro Series Whitening Toothpaste with 5% Hydrogen Peroxide, Enamel Strength, 3 oz Tube

Works well

Costco has it at a better price at 4.01oz with a 4 pack instead of 3.

After a few weeks of using this, I definitely noticed whiter teeth, and this toothpaste has such a strong taste, it will leave you feeling refreshed until the next meal. However, this particular flavor I got is really bad. It's very strong and will leave you refreshed, but when brushing, it tastes just awful. It's not even a mint flavor, but rather a strong chemical flavor. This might be a deterrent to good brushing habits for some, but if you're keen on this toothpaste I'd highly recommend going with the other flavor if you can find it.

I'm a senior and I love coffee. For a long while I noticed my lower teeth in photos looking dim dingy and yes...yellow. I have tried some methods in whitening but nothing seemed to help much. I took the leap and bought this first at the drug store. I noticed a difference almost right away. I've bought it ever since through Amazon (because it is a similar cost as in the store and I don't have to go get someone to unlock the case, a huge time consuming hassle). It actually does make your teeth look much younger. Highly recommend.

Best toothpaste on the market. Too bad Colgate pulled the Enamel Repair formula off the shelves. This toothpaste is so good they knew it was a threat to the dentist industry. So they no longer carry it in stores since the "industry" would lose money if people had a product that actually prevented cavities. They do still carry the whitening and fresh breath versions but not the enamel strength one which contains the highest amount of hydrogen peroxide. Sad

This toothpaste gave me chemical burns on my gums and inside my lip. I suspect it’s the high concentration of hydrogen peroxide as the regular Colgate Optic white gives me no issues. Wouldn’t recommend for sensitive mouths, but works just fine for my husband so buyer beware.

My teeth are noticeably whiter two weeks in - I'm so happy! Taste isn't amazing but you just need a small drop and it's worth it in my opinion. This works even better than their other whitening products.

I've been using this product for about two months now. I was skeptical about its ability to whiten my teeth but it worked, and the whitening was better than I expected. For me there was little change even after one month -- you do have to persist. I plan on continuing to use this product.

Estou usando a quase um mês e dá pra notar um clareamento discreto. Esperava um creme dental mais agressivo, mesmo assim gostei do produto.

بالنسبه لغيره هذا الافضل وله نتائج واضحه لكن ليست سحريه يحتاج لانتظام في الاستخدام حتى تظهر النتائج

Muy lamentable como preparan el producto, como si no les importara: el producto solo tenía un plástico burbuja amarrado con listón, caja muy maltratada, parcialmente abierta, muy fácilmente falsificable, la fecha de expiración con etiqueta sobrepuesta. COSTÓ 20 DOLARES!! el vendedor debería saber que un producto de ese precio, requiere un trato al mismo nivel . El sabor diferente al de una versión comprada en tienda formal. Saquen sus conclusiones. Si no es falso, más a mi favor, que lamentable que por el mal manejo del producto, tiren su reputación completa. Ojalá #amazon pueda supervisar a sus vendedores.

Good to use
