Dentures play a vital role in restoring your smile and helping you eat, speak, and feel confident. But like all dental appliances, they are not designed to last forever. The average denture lifespan is typically 5 to 10 years, depending on the type of denture, the quality of materials, and how well they are cared for. Over time, natural changes in your mouth and wear to the dentures themselves mean replacement will eventually be necessary.
In this article, we’ll cover how long dentures last, the signs you may need new ones, and tips to extend their lifespan.
How Long Do Dentures Last?
On average, most full and partial dentures last between 5 and 10 years. Some may last longer with excellent care, while others need to be replaced sooner due to changes in gum and bone structure.
The lifespan depends on:
- Material used – Acrylic dentures typically last 5–8 years, while higher-quality materials may last longer.
- Fit and comfort – Dentures that no longer fit well are more prone to cracks or discomfort.
- Oral changes – Jawbone shrinkage and gum changes can make dentures loose over time.
- Maintenance – Daily cleaning, proper storage, and avoiding damage all affect longevity.
Signs You Need New Dentures
Even if your dentures are still intact, there are signs that indicate it may be time for a replacement:
- Difficulty chewing or speaking
- Frequent sore spots or gum irritation
- Loose or slipping dentures
- Visible cracks, chips, or worn-down teeth
- Changes in your facial appearance, such as sagging around the mouth
- Persistent bad odour or staining despite cleaning
If you notice these issues, it’s best to visit our dental clinic for an assessment.
How Often Should Dentures Be Replaced?
Dentists generally recommend replacing dentures every 5 to 7 years. While this is an average, some patients may need new dentures sooner, especially if they experience significant bone or gum changes.
Regular dental check-ups are crucial, even if you no longer have natural teeth. Your dentist can monitor your oral health, adjust your dentures if needed, and advise you when replacement is the best option.
Factors That Affect Denture Lifespan
Several factors influence how long dentures last:
- Type of denture – Full dentures often last longer than partial dentures, which may experience more stress.
- Patient habits – Grinding teeth, smoking, or chewing hard foods can shorten their lifespan.
- Cleaning routine – Gentle, consistent cleaning keeps dentures in better condition.
- Material quality – Premium dentures may last longer but still require eventual replacement.
Tips to Extend the Life of Your Dentures
While no denture lasts forever, proper care can maximise their lifespan:
- Clean daily using a soft brush and non-abrasive denture cleaner.
- Soak overnight in water or a denture solution to prevent drying.
- Avoid dropping dentures, as they can crack easily.
- Never use hot water, which can warp their shape.
- Schedule regular dental visits for adjustments and professional advice.
By following these habits, you can keep your dentures functional and comfortable for longer.
