If you have very dark, yellow teeth then you may need to whiten for an extended period of time - we usually recommend using a normal strength gel however to avoid any unwanted sensitivity or gum irritation.

We particularly recommend: One of our 16% or 22% value kits - containing everything you need and enough gel for up to 30 applications which will be plenty to whiten your teeth and allow gel for top-ups at 6-12 month intervals.
