Hello,  I had a Sure Smile teeth whitening treatment performed with UV light with some gel, first for 15 minutes and then 30 minutes afterwards. My teeth were very sensitive and I had a major headache. Also the goggles appear to have burnt the side of my face, is this legal? I said my teeth were lacking enamel. It even hurts to chew. My friend had hers done and she is fine. I wish I hadn’t bothered, has this happened before? Thank you in advance.
