PF 20% Melon, 8 Syringe Refill

Whitens really well - much better than strips. You do need to get trays; I had some custom made at the dentist and use the product about once every three weeks to maintain my desired level of whiteness.

Love this product! Recommended by my dentist. I leave them in all night a few times a month and never feel sensitivity pain like I do with other whiteners.

I ordered an 8pk of Opalescence from seller; product arrived timely and I am happy with product. For those using 15%- you may want to try the 20%- works just about the same- the 5% didn't seem to make much of a difference; however, I would like to comment on teeth sensitivity. If you have sensitive teeth, you may want to continue using what your dentist recommends.

I tried the white strips and while they were good, they were not great. I decided to fork over the money and get the custom whitening trays from my dentist. The kit came with the Opalescence 20% Melon. My dentist said to purchase from her would be costly, but I should try Amazon. I am in the process of getting some old crowns replaced and wanted to whiten my teeth prior to getting the crowns so that the color would match as closely as possible. I am only in the second week, but my smile seems brighter. The price was definitely a plus!

Works good as instructed and was happy with the results. The 20% did not bother my gums and the melon flavor was okay too. Make sure you know the expiration date and keep unused amounts refrigerated.
