The Oral B Pro 3 3900 Electric Toothbrush removes more plaque than a standard manual toothbrush, making healthier gums and whiter teeth easy to achieve.The integrated timer reminds you to switch areas every 30 seconds.360° gum pressure control ensures your gums stay healthy - when the sensor detects you're brushing too hard, the band around the handle turns red and brush speed slows down automatically.And as the Pro 3 3900 removes surface stains, your smile will get visibly whiter, too, starting right on the first day of brushing.The battery lasts for up to 14 days on a single charge, making electric brushing even more convenient.This twin pack includes 2 handles in pink and black, 2 matching toothbrush heads and a charger.
