Loose dentures are usually caused by jawbone loss beneath the denture, which changes its fit over time, but the problem is common and treatable. This guide explains the warning signs, causes, short-term fixes and modern implant-supported alternatives available in Perth.
Key Takeaways
- Jawbone loss is the most common reason dentures become loose.
- Adhesive provides temporary grip but does not correct an outdated fit.
- A reline can improve contact between the denture and gums.
- A new denture fits the current jaw shape but cannot prevent future resorption.
- Snap-on overdentures and All-on-4 use implants for greater stability.
- Medicare does not cover dental implants.
What are the signs that my dentures are loose?
Dentures should remain secure during normal speaking, smiling, and eating. Regular slipping or rocking usually means the fit needs attention.
Common signs include:
- Dentures slipping when you eat, speak or laugh
- Clicking or clacking as the denture moves
- Sore spots or ulcers caused by friction
- Difficulty chewing or avoiding certain foods
- Denture adhesive no longer holding the denture in place
Food may collect beneath the denture, or your bite may feel different. Previously secure dentures usually become ill-fitting because the supporting jawbone and tissues have changed shape.
Why do dentures become loose?
The main cause is bone resorption. After teeth are removed, the jawbone no longer receives normal stimulation from tooth roots. It gradually reduces in height and width, changing the surface that supports the denture.
This can begin during the first year after tooth loss. Lower dentures are often affected more because they have less supporting area and must function around the tongue.
| Cause | Typical timescale | Common response |
|---|---|---|
| Bone resorption | Ongoing from year 1 | Reline or implant-retained option |
| Worn liner | Often 2 to 3 years | Denture reline |
| Outdated fit | Varies | Reline or new denture |
| Weight change | Varies | Adjustment or reline |
Bone resorption
Bone resorption creates gaps between the denture and gums, reducing suction and stability. A conventional denture can be refitted, but it cannot replace natural root stimulation.
A worn denture liner
The tissue-facing surface can wear, compress, or harden. A professional reline adds new material, so the denture matches the current shape of your mouth more closely.
An outdated original fit
Healing, ageing and tissue changes can make the original fit inaccurate. Worn artificial teeth can also alter the bite and cause rocking.
Weight changes
Significant weight loss or gain may alter soft tissue around the jaw and cheeks. A dentist can assess whether an adjustment, reline, or replacement is suitable.
What are the short-term fixes for loose dentures?
The right loose denture fix depends on its age, condition, and fit. These options improve comfort without necessarily addressing bone loss.
Denture reline
A reline adds new material to the inside of the denture so it follows the changed gum and jaw shape. A soft reline is often temporary, while a laboratory-made hard reline is more durable. Relining commonly costs about $300 to $600 per arch.

Denture adhesive
Denture adhesive can temporarily fill small gaps and increase grip. It may also reduce food collecting beneath the denture.
Adhesives do not stop bone loss or correct a worn bite. If it oozes around the edges or needs repeated application, the fit should be assessed.
A new denture
A new denture may suit a cracked, badly worn, or repeatedly repaired appliance. It matches your current mouth, but future bone loss can loosen it.
Some damaged dentures may be suitable for professional denture repair when the remaining structure and fit are serviceable.
What are the modern alternatives to loose dentures?
Relines and new dentures update the fit but do not stop jaw changes. Implant-supported options use implants as anchors and stimulate surrounding bone.
Implant-retained overdentures
A snap-on overdenture usually attaches to 2 or 4 implants using ball or bar attachments. It clips into place but remains removable for daily cleaning.
This can reduce lifting and rocking, especially in the lower jaw. Learn more about implant-retained dentures in Perth or explore the wider range of dental implant options available at Radiant Smiles.
All-on-4
All-on-4 uses 4 implants in a jaw to support a fixed full-arch bridge. It is a common choice for denture wearers who want a fixed solution because the bridge is not removed every day and does not rely on suction or denture adhesive.
Suitability depends on your bone, gums, health, bite, and cleaning ability. Read more about All-on-4 treatment in Perth.
| Feature | Standard denture | Snap-on overdenture | All-on-4 |
|---|---|---|---|
| Secured with implants | No | Yes | Yes |
| Slips or falls out | Can occur | Rarely | No, fixed in place |
| Promotes jaw bone health | No | Partly | Partly |
| Daily removal required | Yes | Yes | No |
| Gagging or speech issues | More common | Less common | No |
How much does each treatment option cost?
Costs vary with implant numbers, bone condition, materials, and additional treatment. The table below compares typical Perth prices for each option.
| Option | Approximate Perth cost | Notes |
|---|---|---|
| Denture reline | $300 to $600 per arch | Temporary fit update; bone loss continues |
| New denture | $1,500 to $3,000 per arch | Fits the current ridge; bone loss continues |
| 2-implant snap-on overdenture | $5,000 to $9,000 per arch | Stable and removable; implants slow bone loss |
| All-on-4 | From $25,000 per arch | Fixed full-arch bridge; most stable long-term option |

Private health insurance with major dental cover may contribute, depending on your policy. Medicare does not cover dental implants.
SuperCare is an option some eligible patients use to apply for early release of superannuation for dental treatment. It may involve an administration fee of about $800, so it should be compared with other funding choices. Read more about using SuperCare for dental implants.
Loose dentures are common, and the right fix depends on whether the cause is a worn liner, an outdated fit, or ongoing jawbone loss. If you are dealing with loose dentures in Perth, we can assess why your dentures are moving and explain the costs, timeframes, and care involved with each option. Book a consultation at Radiant Smiles to discuss conventional, removable implant-retained, and fixed full-arch options.
Any surgical or invasive procedure carries risks. Before proceeding, you should seek an opinion from an appropriately qualified health practitioner.
FAQs on Loose Dentures
How do you fix loose dentures at home?
You cannot permanently correct a poor denture fit at home. Adhesive may provide temporary grip, while softer foods can reduce discomfort. Avoid DIY reline kits or bending clasps because these can damage the denture or alter your bite. Professional assessment is needed.
Why do dentures become loose over time?
Dentures loosen because the jawbone and gums change after tooth loss. The denture retains its original shape while the supporting ridge shrinks. Wear to the liner, teeth, or clasps can add to the problem. A reline, adjustment, or replacement may restore a closer fit.
Can dentures be permanently fixed in place?
Yes, dentures can be permanently fixed in place using implant-supported full-arch bridges such as All-on-4. Snap-on overdentures are more stable than standard dentures but remain removable. Fixed treatment requires surgery and is not suitable for everyone, so your bone health, bite, and cleaning ability must be assessed.
What holds dentures in place?
Upper dentures rely on close contact, saliva, suction, and muscle control. Lower dentures depend more on accurate fit, tongue position, and balanced biting forces. Partial dentures may use clasps. Implant-retained dentures use attachments connected to implants for greater stability.
Are implant dentures better than regular dentures?
Implant-retained dentures usually provide greater stability and reduce slipping. However, they involve surgery, higher costs, and ongoing maintenance. The more suitable option depends on your anatomy, health, preferences, cleaning ability and budget.
How often should dentures be relined?
There is no fixed schedule for every wearer. A reline may be needed when a denture begins moving, trapping food, or causing sore spots. Many liners require attention after several years, but jaw changes vary. A dental assessment can determine when adjustment, relining, or replacement is appropriate.
