Clear aligners are most efficient when they are seated correctly onto your teeth and are grabbing onto the attachments. Propel VPro+ vibrates the teeth gently into the position dictated by the aligners and makes sure they are in the ideal positions.
Simply bite down gently on the mouthpiece while wearing your aligners. There is no need to bite down harder than as needed to support the device. The Propel VPro+ will gradually ramp up to full vibration and automatically shut off after 5 minutes.
