The Best Whitening Electric Toothbrushes

Five brushes with whitening modes compared on stain removal, whitening features, gum gentleness, and cost.

Last updated Jul 3, 2026

We compared five electric toothbrushes with dedicated whitening modes from Oral-B, Philips Sonicare, and AquaSonic. These brushes remove surface stains from coffee, tea, and wine rather than bleaching teeth, so we weight real stain removal above marketing claims.
