We compared two at-home LED teeth whitening kits: the Pdoo Teeth Whitening Kit with LED Light and the Mr.Whitener LED Teeth Whitening Kit.
What we looked at
Gel supply, sensitivity formula, and price.
The verdict
If you want 5 syringes of premium whitening gel with a wireless, water-resistant LED unit, the Pdoo is the pick at £31.98, though it costs £13.03 more. If you would rather pay less for 8 pre-measured, peroxide-free PAP+ gel pods designed for daily sensitive-tooth use, the Mr.Whitener is the value option, at £18.95.
