Review: Good product! - I used the first 4 syringes and they worked fine... The results weren't so radical as what I wanted for my wedding so I went on and used the second set. With the second set I didn't feel the side effects (yes, it is true, it makes your teeth sensitive and it is kind of painful, but nothing excessive, it is tolerable) and I didn't seem to work as the previous one... So I contacted desertcart customers support and they were amazing!!! They gave me a refund and since I live in Venezuela and told them I would not be able to use the refund with my credit card because of the very strict currency exchange control policy the government has here, they gave me like q bonus to be collected any time with any product purchased from desertcart! These people are great! They really know how to keep customers happy! I love them, and especially all those who took care of my case!! I couldn't be more satisfied. The product works, I don't know what happened with the last syringes I got, but anyways my dentist said that results with the first 4 syringes was fine, and that I had used it long enough. The secret to it not making your teeth so sensitive is not using too much product at a time, and also, trimming the trays (I used the moldable ones sold on desertcart as well) so that they do not cover your gums (my dentist told me so and it was a real relief afterwards) because if they are covered by the tray, the product irritates them.
Review: Works great - I used this for one hour and noticed my teeth were visibly whiter. Unlike Zoom, this product did not irritate my teeth. Do not use this for 8-10 hours (like the directions say) as this will most likely cause sensitivity. My Dentist recommends this product and said to wear it for 1 hour (not 8) at a time. The expiration date is on the instructions, and it comes sealed with the tube. The expiration date was over 2 yrs out on the one I received. There is no flavor to this...it is not mint. It says mint, but it is completely tasteless. It is also very (very) sticky, so kind of different than the other whiteners, but I really like this one. I was in so much pain after using the Zoom whitening (16%) that Advil didn't even help. I would recommend this product because it has been working great for me.
