Question and answer

How long do false teeth last

The service life of dentures depends on material, fit, wear, cleaning, jaw changes, and whether they are full or partial.

The short answer

Dentures do not have one fixed lifespan; fit and function can change as acrylic teeth wear, the base ages, and the jaw and gums change shape. A dentist decides between adjustment, relining, repair, or replacement after checking the appliance and tissues.

What is the difference between complete and partial dentures?

A complete denture replaces all teeth in one arch, while a partial denture replaces some teeth and uses the remaining teeth for support. The base may be acrylic or metal, and each material has different repair and fit considerations.

How should you care for false teeth and your mouth?

Remove and clean the denture as instructed, brush the appliance with a denture brush, and clean the gums, tongue, and remaining teeth. Store it in water or the recommended solution when out of the mouth, and never adjust it with tools.

When should changes in denture fit be assessed?

Book a review for looseness, rocking, sore spots, cracks, clicking, chewing difficulty, or a change in speech. Prompt care is needed for persistent ulcers, bleeding, swelling, or a broken appliance that could be swallowed.

What could be causing your false teeth to become unstable?

Ask whether the problem is wear, loss of fit, a damaged base, or a change in the supporting ridge. Ask whether adjustment, a reline, repair, a new denture, or an implant-supported option is suitable.

Frequently asked questions

Can a loose denture be relined?

A reline can adapt the fitting surface when the base is suitable, but a damaged or severely worn appliance may need replacement.

Should I sleep in my dentures?

Ask your dentist about your specific appliance and tissues; many patients remove dentures for cleaning and to allow the supporting mucosa to rest.
