Takes practice, but makes a difference
7 May 2019
I found the tray moulding a little challenging but it did work after two tries. The main issue is how hot the water needs to be - if not hot enough it doesnt mould properly and if too hot it skews the shape of the mould. After 3 applications I noticed a difference and after 5 there was a really noticeable improvement. There was some tooth sensitivity but it disappeared after a few hours and lessened each time I applied the gel even though I kept the mould in for 45 mins. I think the blue light does escalate the whitening process, after using other gels that didnt come with the light. Overall, it is an effective [roduct for a very reasonable price.
