Dentures are designed to restore your smile, improve chewing, and support clear speech. But like natural teeth, they also require regular care and professional monitoring. Many patients ask us: How often should I get my dentures checked? or How often should dentures be replaced?
If you wear full or partial dentures, understanding denture maintenance and care is essential for long-term comfort and oral health. Here’s what you need to know about when you should have your dentures checked, relined or replaced.
Why Regular Denture Check-Ups Matter
Even if your dentures feel comfortable, your mouth continues to change over time. After tooth loss, the jawbone naturally shrinks. According to research, bone resorption (bone shrinkage) occurs progressively after teeth are removed, which can affect how dentures fit and function.
When dentures no longer fit properly, you may experience:
- Loose dentures and gum changes
- Sore spots or ulcers
- Difficulty chewing
- Changes in speech
- Food getting trapped underneath
Regular professional denture check-ups help detect these issues early and prevent complications.
How Often Should Dentures Be Checked?
In general, dentures should be checked at least once a year to ensure they still fit snugly on you.
At Dentist Near Me Merrylands, we recommend annual reviews even if you have no discomfort. During a denture check-up, we assess:
- Fit and stability
- Gum health
- Signs of wear or damage
- Bite alignment
- Oral tissues for irritation or infection
For new denture wearers, more frequent visits may be needed in the first year as your gums and bone settle.
If you notice signs that your dentures no longer fit properly, such as movement while speaking or eating, it’s best to book an appointment sooner rather than waiting for your annual review.
How Often Do Dentures Need Relining?
Now that you understand the general timeline on when dentures should be checked, let’s look at when and how often you should reline them. Relining involves reshaping the underside of your denture, so it better fits your gums after natural changes in your mouth.
Denture Relining Frequency
Most patients require a denture relining every 1 to 2 years, depending on various factors, including:
- Rate of bone shrinkage
- Changes in weight or health
- Comfort and stability
- Whether you wear full or partial dentures
In the same research, it was shown that ongoing bone resorption significantly affects denture stability, which often necessitates relining to maintain the teeth’s function.
Relining may help in:
- Improving comfort
- Reducing movement
- Preventing sore spots
- Extending denture lifespan
Adjusting and relining dentures is a common and straightforward procedure that can make a noticeable difference in how your dentures feel.
How Often Should Dentures Be Replaced?
Relining can improve how your denture fits. However, it’s also important to remember that dentures do not last forever.
Denture Lifespan in Australia
On average, dentures should be replaced every 5 to 8 years, depending on how well you care for them. Our mouths are always exposed to different elements, especially when we eat.
Over time, dentures:
- Wear down from chewing
- Lose their natural shape
- Stain or discolour
- No longer match your facial structure
In this research, it was found that prolonged use of ill-fitting dentures may increase the risk of oral lesions and discomfort. The research showed that 50% of people wearing full dentures had some type of oral lesion because of ill-fitting dentures.
Replacing dentures at the appropriate time helps maintain:
- Proper bite alignment
- Jaw support
- Facial appearance
- Healthy oral tissues
Your dentist will assess when to replace dentures based on your individual condition.
Signs It May Be Time to Reline or Replace Dentures
If you’re unsure whether you need adjusting, relining, or a full replacement, look out for these signs:
- Dentures feel loose or unstable
- Clicking sounds when speaking
- Frequent sore spots
- Difficulty chewing foods you once managed easily
- Cracks or visible damage
- Changes in facial appearance (sunken cheeks)
- Persistent bad breath despite cleaning
These may indicate changes in your gums, jawbone, or denture structure. If you feel any of these signs with your dentures, it’s best to visit your dentist as soon as possible to help you get a more comfortable denture experience.
Denture Maintenance and Care
Good denture care helps with comfort, hygiene, and lifespan. When there is a lack of denture hygiene, it will likely increase the risk of denture-related inflammation or denture stomatitis.
To take care of your dentures, make sure you keep it simple, like when you’re taking care of your teeth and gums:
- Clean daily: Brush dentures with a soft brush and non-abrasive cleanser, and rinse after meals.
- Clean your mouth too: Gently brush your gums and tongue (and natural teeth if you have partials).
- Remove at night: Let your gums rest, unless your dentist advises otherwise.
- Store safely: Keep dentures moist in water/soaking solution and avoid hot water.
- No DIY fixes: If they feel loose, rub, or click, book a check-up for an adjustment or reline.
Supporting Comfortable, Long-Term Denture Use
Looking after your dentures is an important part of protecting your comfort, confidence, and overall oral health. With regular check-ups, timely relining, and replacement when needed, dentures can continue to function well and support your smile for many years. Small adjustments made at the right time can prevent bigger issues later.
If you’ve noticed looseness, discomfort, or changes in how your dentures fit, it may be time for a professional review. Talk to our dentists at Dentist Near Me Merrylands to get your dentures and oral health checked.

Frequently Asked Questions
How often should I get my dentures checked?
As a general guide, dentures should be checked at least once a year. A professional review helps confirm the fit is still stable and comfortable, and allows your dentist to check your gums and oral tissues for irritation.
How often do dentures need relining?
Many people need a reline every one to two years, as the gums and jaw can change shape over time. If your dentures are starting to feel loose, rub, or trap food underneath, a reline may help improve comfort and stability.
How often should dentures be replaced in Australia?
Dentures commonly need replacement around every five to eight years, depending on wear and how well they still fit. Over time, they may lose their shape, stain, or no longer support your bite as well as they used to.
What are the signs my dentures no longer fit properly?
Common signs include looseness, clicking when speaking, sore spots, difficulty chewing, or changes in how your face is supported (such as a more “sunken” look). If you notice any of these changes, it’s worth booking a check-up sooner.
Can I adjust or repair my dentures at home?
It’s best not to. DIY adjustments can damage the denture or irritate your gums and may make the fit worse. If something feels off, your dentist can assess whether a simple adjustment, reline, or replacement is the safest option.
Should I sleep with my dentures in?
Many people are advised to remove dentures at night to allow the gums to rest, but this can vary depending on your situation. Your dentist can give guidance based on your oral health and the type of denture you wear.
How do I care for my dentures day to day?
Daily cleaning and safe storage are key. Brushing dentures with a soft brush and a non-abrasive cleanser, rinsing after meals, and keeping them moist when they’re out of your mouth can help maintain comfort and hygiene.
