OpalescenceGel Syringes Teeth Whitening - Refill Kit - -D- 5771-1

My dentist recommended Opalescence. It must be used with custom made trays, however. I recall that was $200 to get those made. He also recommended I start with 10% to test my sensitivity. I had no reaction to 10% but 15% just starts to leave me a little sore after a nights use - of course, it's 50% stronger! I've stayed at 15% and deal with the small amount of soreness, which usually disappears after a day.Still, the results have been remarkable, especially considering I drink coffee and smoke. This product, used regularly over night, has made my teeth whiter than they've been since I was a child. People actually asked me if I'd had dental work done because my smile looked so good.Highly recommended. Start with 10% if you haven't used this before. I think my dentist was right to suggest that.

Used this product after my dentist treated me with it. It worked quite well. Bought it on Amazon considerably cheaper. I use the treatment twice a year and my teeth are always quite white. Do not use too much of it, it will make your gums very sensitive. If you stop using it for a couple of days, it will go away. Great product!

Lo recomiendo, 4 días y ya se ve los resultados.

I usually buy this product at the dentist, and the price at this site was a fraction of what I usually pay. The shipping was a complete rip-off, though, as I paid about $15 when it cost them $2 to ship it to me. This cut in to some of my savings, but overall, I did still save money. I certainly would never buy a product at its regular price from this company.

This was not the same thing the I got from my dentist. It’s matches everything including brand but was awful.

My only complaint is how long shipping took. The product came as described and was packaged well.

it worked great even for my bonded teeth not absolutely white but a good imrovement

This is the same product I have gotten from my dentist for years. This is much cheaper and identical.It is perfectly fresh. I use it for touch ups since my teeth have already been professionally whitened.Keep the unused syringes in fridge. The 15% is perfect for me, without burning my gums. I use it overnight.Be careful, don't overfill trays,a stronger version is not necessarily better or faster and can burn.
