If you own any brand or model of electric toothbrush outside of the ones explicitly mentioned above, we highly recommend purchasing the PRIMALS Boar Bristle Electric Toothbrush or PRIMALS Horse Bristle Electric Toothbrush to ensure compatibility, and for the best microplastic-free and low-EMF sonic brushing experience. Each PRIMALS Electric Toothbrush comes with 2 free replacement heads.
PRIMALS is not affiliated with or endorsed by Philips or Philips Sonicare. Compatibility is based on handle design only.
Boar Bristles vs Horse Bristles
The PRIMALS Boar Bristle Replacement Heads are the world's first natural-bristle heads for electric toothbrushes. Two options to choose from:
Boar Bristle Heads - Firm yet gentle natural bristles for a deep, powerful clean. Ideal for anyone who prefers a thorough scrub that digs into plaque and buildup. Naturally antimicrobial so your brush head stays cleaner between uses.
Horse Bristle Heads - The softest natural bristle available. Perfect for sensitive gums, receding gumlines, or anyone who prefers a gentler brushing experience.
Both are 100% natural, plastic-free, glue-free, and antimicrobial. Replace every 1 to 3 months. Available in 4-packs. Subscribe for automatic delivery so you never run out and never go back to plastic.
