Philips Sonicare G3

Philips Sonicare G3 scores 40/100 on Scout's independent analysis of ingredients, additives, and lab results — a below-average score in Scout's analysis. The G3 is a replaceable electric brush head made of plastic (counted as 70% bio-based on a mass-balance basis, an accounting method rather than guaranteed content), rubber and nylon bristles with a fading blue dye, plus an RFID chip — so every head swapped out every three months is mixed plastic and electronics that only TerraCycle takes back.

Philips Sonicare G3 ranks #8 of 10 toothbrushes in Scout's independent rankings. The current top score in the category is Toxin Dodger Horse Hair & Bamboo Toothbrush at 90/100.

In Scout's ingredient-by-ingredient analysis, Paper-based recyclable packaging counts in its favor; Nylon bristles, RFID microchip are flagged as ingredients of concern. The full breakdown, with why each one matters, is in the Key ingredients section on this page.
