Dentures are not tooth replacements that last a lifetime. Instead, they have a “life span” and must be relined or replaced over time to maintain high-quality results. But how can you know if a problem exists that warrants this type of treatment? One way to know if your denture needs to be relined is to keep reading or speak to a member of your dental team to find out the signs to look for and what you can expect should you need your denture relined.
