The Oral-B Professional Care Oxyjet Refills are a replacement irrigator head for the Oral-B OxyJet. Oxyjet technology infuses water with micro bubbles and streams them to attack plaque bacteria below the gumline.
Dental professionals recommend replacing your toothbrush every 3-4 months, or earlier if the bristles become spread out or frayed. The Oral-B Professional Care Oxyjet Refills feature indicator bristles that fade halfway to help remind you when to replace your toothbrush head so you maintain a superior clean vs. a regular manual toothbrush. When bristles are worn out, cleaning effectiveness decreases.
