There are apprently some teeth whitening kits that have a bleach in them that long term is damaging to the teeth. Does this kit have anything in that could damage or weaken the teeth?

Hi Beryl,
Thank you for you questions..
Firstly, there is no harmful bleach in our product which makes it totally safe to use. It has been formulated by dentists and dental laboratory technicians.
The treatment is 45 mins x1 daily for 12 days.
