every 3 months you are suppose to re whiten but thats about average for whitening systems

These are those teeth plates? I've been using Crest 3D whitening toothpaste. That's working well, but I find that certain patches are whiter than others, which is a little weird; does that happen with those?

no these are little amulets with whitening liquid that is made for people with sensitivity to normal whiting strips and you brush it on. ive never ad that happen in any whitening system. so i don't know.

That's nice. I'd much rather brush it on than wear those strips.
