I have used Enlighten as my teeth whitening system for around 10 years. I get decent results and my patients are consistently happy. There are several different strategies for minimising sensitivity within the system which I like as this is the one major aggravation for patients when whitening. It dosnt always eliminate the sensitivity but makes it manageable in the dentitions that are prone to getting lively. The presentation of the product is attractive and it looks like a luxury brand. As a company Enlighten are very helpful and their marketing material is well put together. I would certainly recommend Enlighten.
