Nothing last forever and same goes for dentures. Frequently dentures may require repairs or additions. If the dentures or partials have been designed with proper planning, most likely they can be repaired successfully. Teeth and clasps can be added to fill empty voids in you dentures which will make them fit better and you will be able to enjoy your food once again. Sometimes laser welding or frame / clasp extension casting may be required, this will take much longer than your ordinary simple repair which can be usually done within an hour.
