Restarting Retainers You Stopped Wearing Years Ago

If you’ve noticed your teeth starting to drift following orthodontic treatment, it is not too late to get back on track, even with retainers you put away ages ago.

The most important consideration in restarting a retainer you stopped wearing years ago is whether it still fits comfortably. If you try it out and the retainer feels tight, painful, or doesn’t seat fully, there’s a good chance your teeth have shifted. In these cases, it’s important to see a dentist and get a properly fitted appliance rather than forcing the old one back in.

Why Teeth Move After Braces or Aligners

Teeth are held by ligaments and bone that remain flexible throughout life. Without a retainer holding them in place, they tend to drift back toward old positions. This is why retention is a lifelong part of orthodontic care. At Dental Care of Corona, retention after Invisalign® or Six Month Smiles® typically means wearing a retainer while you sleep to keep your teeth aligned.

Should You Put the Old Retainer Back In?

If an old retainer slips on easily and feels snug but not painful, it may still be up to the task of holding your smile where it needs to be. If it feels tight, pinches, or will not fully seat, stop. A retainer that no longer fits is a sign that your teeth have moved. Forcing it in can hurt your teeth or crack the retainer.
