Retainers may be removable or fixed. They hold your teeth in their new, correct positions after your teeth have been straightened. We recommend wearing your retainer every night for as long as you would like your teeth straight. Make sure to care for your retainer well by brushing your retainer every morning with cool water and toothpaste, and putting the retainer directly into it’s case and away somewhere safe like a drawer or cabinet. Please let us know as soon as possible if your retainer is ever lost, broken, or does not fit.
