You’ll return for your next appointment and receive your first set of aligners. Each aligner, or tray, is worn 20-22 hours each day for maximum results. Gradually your teeth will shift according to the treatment plan. You may even start seeing results after a few weeks. Based on decades of expertise in material science and biomechanics, each aligner is made from SmartTrack® material which is engineered for comfort, predictability, and gentle force. By using this smooth, durable plastic instead of metal brackets and wires, many of our patients experience fewer emergency visits and less hassle during their orthodontics treatment. Find out if Invisalign is the orthodontic solution you need for a healthy, beautiful smile.
