Byte at-home impressions will be shipped to you with instructions. They help you remotely track your progress throughout the process. You can get up to $ 100 off for all the friends you refer. They only use doctor-prescribed treatments to ensure you get the best results. The aligners are made with BPA-free plastic. All-day aligners work very fast; you can be done within 3-4 months. But that only happens when you wear the braces more than 22 hours every day.
