Many people struggle with teeth stained by coffee, tea or aging enamel. Temporary whitening kits deliver uneven results and fail to remove deep pigments.

That slow progress and mixed outcomes frustrate anyone aiming for a quick boost. This results in repeated spending on kits that fail and wasted time.
