ORAL B FLEXISOFT HEADS REFILLS 4S

Oral b flexisoft heads refill 4s are replaceable electric toothbrush heads replaced after some time. Electric toothbrush bristles vibrate or rotate to help you remove plaque buildup from your teeth and gums. The vibration allows for more micro-movements every time you move your toothbrush across your teeth. The head is replaceable after some time as it tends to wear off due to friction.
