The bristles change color from green to yellow, signifying optimal cleaning performance and signaling when a fresh head is needed for the best results. Experience a thorough clean that reaches deep between teeth and along the gumline, effectively removing plaque and promoting healthier gums. Compatible with most Oral-B electric toothbrushes.
