Once damaged, change: Once a clear aligner is damaged it need to be replace. They are not providing the treatment intended anymore.

Replace: Mouth guard type clear retainers have a tendency to wear through over time usually due to night time grinding of the teeth. You should have a new one made but depending on which arch (upper or lower) grinds through other types of retainers with wires along with acrylic can be made.

Talk to Orthodontist: Perhaps a different type of retainer would better suit your stabilization and grinding requirements. Talk to an orthodontic specialist.

Repair or replace: The average lifespan of a plastic retainer is about 3 to 5 years. If damaged, plastic retainers require repair or replace by an orthodontist. See your orthodontist. dentist for treatment options.
