The next phase is called retention, and it is a critical follow-through stage that holds your teeth in their new placements — and even continues to provide minor corrections in some cases.
If you follow your orthodontist’s instructions after he removes your braces, your new and improved smile will last a lifetime.
Your orthodontist will fit you for a retainer, which is an appliance you wear over your teeth to keep them perfectly in place.
Without a retainer, all the improvement you see from your past couple years in braces will undo itself relatively quickly.
The orthodontist will probably ask you to wear your retainer every day and night for several months, subsequently during sleep and eventually a few nights per week.
