Will my old retainers fit my new crown?

Hi,

Welcome to icliniq.com.

Retainers are an essential part of orthodontic treatment as they keep all the corrections achieved during the orthodontic treatment intact till bones and surrounding tissues mature. In general, it takes approximately one year for this process to complete since the end of the treatment. Beyond this time, as the tissues mature, the tendency for teeth to move or shift gradually keeps decreasing. Hence, full-time retainer wear is reduced to nighttime, followed by alternate daywear to a time where retainers will not be required. I would recommend you visit the orthodontist and get the new measurements and the crown, get a new set of retainers and wear them for at least six months. If you have already spent more than one year since the completion of the orthodontic treatment, most of your teeth and surrounding tissues would have settled and matured. Hence, six months should be sufficient. Else wear the retainers for one year total. All the corrections achieved by the orthodontist might be lost if you do not comply with the retainers protocol, and your time, energy, money, pain, etc., would be a waste. And to regain all the corrections, you would have to undergo the whole process again. So get the measurements and a new set of retainers and comply with the protocol. That will be the only advice. Do reach out for further information or clarifications. Regards.
