One of the things, that I absolutely hate, is when someone has yellow teeth, or they do not take care of their teeth. All I can say is wow! After whitening for a short quick 10 minuets, I looked in the mirror and said "Wow, this stuff really works!" Green-Heart's Professional Whitening Kit is made of 44% Carbamide Peroxide. Normal directions state that you can whiten your teeth in as little as 20 minuets. However, do the sensitivity that I have had in the past, I needed to purchase a remineralization gel to do prior to the whitening. I as well only went half time, and can only imagine how white my teeth would really get if it was on the full 20 minuets. I have used other whiteners directly from the Dentist , strips, other gels, and even charcoal caps (which were completely messy), and by far Dr Song's product has out performed them all!
The kit comes with 2 syringes of the whitening gel, so I have plenty for touch-ups, and a little goes a very long way. I as well love that it includes a wonderful pliable soft tooth/mouth guard, as well as a small spreader to evenly distribute the gel. It as well includes a light which is only used as an accelerator to speed things up.
I can tell you that I highly recommend this product, and that it has
done a great job, and has by far, surpassed any other product that I have used. I feel that for the price, this is an excellent deal, as the package has everything included that you would use. I look forward to seeing how white my teeth really can get by using this product. If you follow the instructions that are provided, you won't be disappointed.
