The white stuff on your retainers is usually mineral buildup (tartar) or plaque, which can develop over time from saliva and lack of regular cleaning. While it’s not dangerous at first, it can affect the fit, clarity, and hygiene of your retainer if not removed. You can try doing a deep cleaning using retainer-safe cleaning tablets or solutions to remove the buildup. However, if the buildup doesn't come off or your retainer is over a year old, it might be time for a replacement.
