Almost 12 percent of Australian adults wear dentures, and the figure rises sharply after age 65. A well made denture can last five to eight years, but the gums and bone underneath keep changing shape, which is why a reline is usually needed every one to two years. Good daily care and regular checks are what keep a denture comfortable, secure and easy to live with.
Key takeaways
- Clean dentures twice a day and never with regular toothpaste, which is too abrasive.
- Take dentures out overnight to rest the gums and reduce infection risk.
- A reline reshapes the fitting surface to match gums that have changed, usually every one to two years.
- A loose, rubbing or clicking denture is a sign a reline or review is due.
- Dentures generally need replacing every five to eight years even with good care.
How to clean dentures the right way
Dentures collect plaque and stain just like natural teeth, but the material scratches easily. Use a soft denture brush or a soft toothbrush with mild soap or a denture cleaner, not standard toothpaste. Brush all surfaces over a folded towel or a basin of water so a dropped denture does not crack. Soak them daily in a denture cleaning solution to lift staining and bacteria, then rinse well before putting them back in.
Cleaning the mouth matters too. Brush your gums, tongue and any remaining teeth morning and night. If you have some natural teeth alongside a partial denture, keeping those teeth healthy is essential, since decay and gum disease around them can lead to the partial no longer fitting.
Why you should take them out at night
Wearing dentures around the clock keeps the gums under constant pressure and creates a warm, moist space where a fungal infection called denture stomatitis can develop. Leaving dentures out overnight lets the tissues recover and lowers that risk. Store them in water or a cleaning solution so the material does not dry out and warp.
What a reline is and when you need one
After teeth are removed the jawbone slowly shrinks, especially in the first year. The denture stays the same shape while the gums beneath it change, so over time the fit loosens. A reline adds new material to the fitting surface so the denture matches the current shape of your gums again. It does not change the teeth or the look, only the part that sits against the gum.
Signs a reline is due include a denture that slips when you talk or eat, food getting trapped underneath, sore spots or rubbing, a clicking sound, or needing more adhesive than before. Most denture wearers benefit from a reline every one to two years, and a yearly check lets your dentist or prosthetist catch a poor fit early.
Reline versus new denture: general cost guide
The ranges below reflect the general Australian market and are not a quote. The right choice depends on the age and condition of your denture.
| Service | Typical market range (AUD) | When it suits |
|---|---|---|
| Soft reline | $300 to $600 | Tender gums, temporary comfort |
| Hard reline | $300 to $700 | Routine fit correction |
| Full denture remake | $1,800 to $4,500 | Worn teeth, repeated poor fit, age over 5 to 8 years |

When a denture stops fitting altogether
If relines no longer hold, or the denture rocks no matter what, the underlying bone may have changed too much for a conventional denture to stay secure. Implant retained dentures, which clip onto a small number of implants, are one way to add stability. Our guide to dental implant costs explains how that works.
Frequently asked questions
Can I sleep in my dentures?
It is better not to. Leaving them out overnight rests the gums and lowers the risk of fungal infection. Soak them while you sleep.
Why has my denture suddenly become loose?
A sudden change can follow gum shrinkage, weight loss or a cracked denture. Have it reviewed rather than relying on more adhesive.
How long should a reline last?
A hard reline typically holds for one to two years before the gums change enough to need another. Soft relines may need redoing sooner.
Is denture adhesive bad for my gums?
Used in small amounts it is fine, but needing more and more is a sign the fit has changed and a reline is due.
How often should I see the dentist if I wear dentures?
At least once a year, even with no natural teeth, so the fit, the gums and the soft tissues can be checked.
The takeaway
Dentures last longer and feel better with daily cleaning, a nightly rest and a reline every one to two years as your gums change. If yours slips, rubs or clicks, it is time for a review rather than more adhesive. To have your dentures checked or relined, contact the team at Lumi Dental or see our pricing page.
