How long are dentures supposed to last
Dentures have no fixed lifetime; fit, wear, mouth changes, and daily care determine when they need adjustment, relining, or replacement.
The short answer
Dentures are removable appliances that replace missing teeth and some surrounding gum contours, and their service life depends on fit, wear, and changes in the mouth.
Why can denture fit change after teeth are lost?
Acrylic teeth and denture bases wear during chewing, while the jawbone and gum ridge can slowly remodel after tooth loss. These changes may make a once-fitting denture loose even when the appliance looks intact.
How should you clean and store your dentures daily?
Remove dentures for the cleaning routine advised by your dental team, brush the appliance with a denture brush, clean your gums and tongue, and store the denture as directed. Have the fit checked when it rocks, rubs, cracks, or affects speech or chewing.
When should looseness or soreness be checked by a dentist?
Book an examination for sore spots, repeated ulcers, looseness, a fracture, or difficulty eating. A persistent mouth sore, unexplained lump, or change that does not heal needs prompt assessment.
What should you ask about adjusting or replacing dentures?
Ask whether the denture needs adjustment, a reline, repair, or replacement; whether the bite has changed; and whether implants or another prosthesis are suitable alternatives.
Frequently asked questions
Why does an old denture become loose?
The supporting gum ridge can remodel, and the denture teeth or base can wear, changing contact and stability.
Can a cracked denture be repaired at home?
No. Household adhesives can damage the material or alter the fit; a dental laboratory or dentist should assess the break.
