🦷 Opalescence Home Teeth Whitening Gel - 4 Pack of 20% Syringes - Mint Review

I have been purchasing this product for many years since 2009 in preparation for our daughters wedding. I've tried different strengths and settled on this 20% that works best for me.

An old or defective product that does not work. Not like buying from the manufacturer. I bought directly from the manufacturer and received the product from my dentist. Nothing like that.

I recommend buying directly from the manufacturer. There are also no returns, so be careful with the buyer.

I didn't feel any discomfort or sensitivity, but the mint flavor was barely noticeable and my teeth didn't appear to have changed white at all. Again, I only used 20% once in four hours, giving him more time to…

What I love about it is that my brother (my dentist) recommended Opalescence to me after he made me my first set of trays. Now that his practice is out of state, I no longer have the old connection. On a whim I searched to see if I could find it somewhere else and low and lo and behold, Revain has it! What I'm going to say is that you need to make sure you're getting the right concentration and only use it for the recommended amount of time. This product may cause some tooth sensitivity, but…
