How long can dentures last
Dentures can last for years, but fit, bite, material wear, and daily care determine when adjustment, relining, or replacement is needed.
The short answer
Complete dentures replace the visible teeth and some gum contour with acrylic resin, while removable partial dentures also use a metal or acrylic framework and replacement teeth. The mouth changes after tooth loss, and the denture materials wear, so a once-comfortable appliance can gradually lose its fit.
How should you clean and store dentures when not worn?
Remove the denture at night unless your dental team gives different instructions, clean it with a denture brush and appropriate cleanser, and store it in water when the material requires moisture. Arrange examinations so the dentist can check the mucosa, bite, retention, cracks, worn teeth, and whether a reline or new denture is the better treatment.
When should slipping or a sharp denture edge be checked?
Seek care when the denture causes a sore area, slips during speech or chewing, cracks, develops a sharp edge, or no longer lets you chew comfortably. Prompt assessment is important for persistent mouth ulcers, bleeding tissue, facial swelling, or difficulty swallowing.
What could explain a denture losing support or comfort?
Ask whether the problem is loss of tissue support, worn denture teeth, a damaged base, or an unhealthy mucosa. Ask whether adjustment, relining, repair, or replacement will restore function, and how often the denture and oral tissues should be checked.
