I had yellow teeth ever since I was a kid. I tried many home remedies for teeth whitening and it failed. One of my friends suggested me to visit Dentzz. I met with Dr. Shuchita, he informed me that I was suffering from fluorosis coz of excess fluorine content in the water. I took an instant teeth whitening treatment, and the results are good. My teeth look so much whiter and brighter, and I love smiling now! Thank you dentzz!
