Once you finish treatment, your teeth will be perfectly aligned and your smile will look amazing! Now it’s time to protect your investment – with a retainer. Retainers are clear plastic trays that are custom made to fit your new smile perfectly. They are worn full time for a few months until your teeth have stabilized and gotten used to their new position. After that, they can be worn at night time only. Studies have shown that teeth will always have a tendency to want to get crowded, so we recommend wearing your retainers every night for as long as you want to keep them straight. For most people – that’s for life! The great thing about clear plastic retainers is that they also protect your teeth from night time grinding, so it’s a win-win. Retainers are night-time for life-time!
