HX 70011 single replacement head for the Philips Sonicare Elite
In six months, your Sonicare brush head delivers over 22 million brush strokes. So even though it may not look worn, it probably is. And a worn-out brush can reduce the effectiveness of your Sonicare toothbrush. Thats why we recommend replacing your brush head every six months. Patients with orthodontics should replace brush heads every four months.
