Though dentures will last for many years, some damage is inevitable and occurs gradually with regular wear. The mouth and jaw change over time which can cause dentures to fit poorly. It is possible for improper fit to damage dentures, as misalignment may cause undue stress to the devices when the patient bites down. Furthermore, metal clasps, more common in dental bridges, can come loose or break off. Some dentures get damaged suddenly from an impact. The American Dental Association recommends dentures be evaluated by a professional when the prosthetic teeth are ill-fitting or damaged. We encourage patients to do the same if they misplace their dentures. Patients may find it beneficial to use denture adhesive to help get used to dentures. Dentures should be checked for fit when they become loose and need more adhesive to stabilize. If dentures fall out, the impact could damage and crack them.
