Dentures can restore your smile, help you eat comfortably and support clear speech. But they are not designed to last forever. Over time, your mouth changes and dentures wear, which can affect how well they fit and function.
Many denture wearers put up with discomfort for longer than they need to, simply because the changes happen gradually. Knowing the signs that your dentures need attention can help you stay comfortable and protect your oral health.
Why dentures change over time
When natural teeth are lost, the jawbone that once supported them slowly shrinks. This process, known as bone resorption, continues over the years. As the shape of your gums and jaw changes, dentures that once fitted perfectly can become loose.
At the same time, dentures themselves wear down. The acrylic base can wear and become stained, and artificial teeth can chip, crack or flatten from years of chewing.
Because these changes are gradual, you may not notice them at first. But eventually they can affect comfort, appearance and how well you can eat.
What is a denture reline?
A reline involves reshaping the fitting surface of the denture, the part that sits against your gums, so it matches the current shape of your mouth. New material is added to the base to fill gaps and restore a snug fit.
Relines can be done in different ways:
- Hard relines use a durable acrylic material and are a common long-term solution.
- Soft relines use a more flexible material, which can be helpful for people with sensitive or tender gums.
A reline can often refresh the fit of a denture that is otherwise in good condition.
Signs your dentures may need a reline
Loose or slipping dentures
If your dentures move when you talk, eat or smile, the fit has likely changed. Many people notice they are relying more on denture adhesive than they used to.
Sore spots or irritation
Poorly fitting dentures can rub against the gums, creating sore spots, ulcers or redness. If you find your gums are often tender, a reline may help.
Food getting trapped
Gaps between the denture and your gums can allow food particles to collect underneath, which can be uncomfortable and make it harder to keep your mouth clean.
Difficulty chewing
If chewing feels less effective or you avoid certain foods, the fit or bite of your dentures may have changed.
Clicking or changes in speech
Loose dentures can click when you talk or make it harder to pronounce certain words clearly.
Signs it may be time to replace your dentures
Sometimes a reline is not enough. You may need new dentures if you notice:
- Worn or flattened teeth. Over time, artificial teeth can wear down, affecting your bite and the shape of your face.
- Cracks or chips. Damage to the denture base or teeth can be repaired in some cases, but repeated damage may signal it is time for a new set.
- Changes in facial appearance. Worn dentures can cause the lower face to look shorter or more sunken, as they no longer support the lips and cheeks properly.
- Persistent discomfort. If problems continue even after relines and adjustments, new dentures may be the best solution.
- Staining and odour. Older dentures can become stained or develop odours that are difficult to remove.
- Age of the dentures. Many dentures need replacing after several years of use, depending on how they have been cared for and how much your mouth has changed.
Why it matters
Ignoring poorly fitting dentures can lead to more than just discomfort. Over time, it may contribute to:
- Ongoing gum irritation and sores
- Difficulty eating a balanced diet
- Fungal infections in the mouth
- Speech difficulties
- Reduced confidence when socialising
Regular check-ups give a professional the chance to spot these issues early. It is also worth having any sore spot that does not heal within a couple of weeks looked at, so the cause can be found and treated.
How to look after your dentures
Good care helps your dentures last longer and keeps your mouth healthy:
- Remove and rinse dentures after eating
- Clean them daily with a soft brush and a cleaner designed for dentures
- Handle them carefully over a folded towel or a sink of water in case you drop them
- Soak them overnight, if recommended for your type of denture
- Clean your gums, tongue and any remaining natural teeth
- Avoid hot water, which can warp some denture materials
- Do not try to adjust or repair dentures yourself
How often should dentures be checked?
Even if your dentures feel fine, regular check-ups are recommended so a professional can assess the fit, check your gums and look for signs of wear. Your clinician will advise how often you should be seen based on your individual needs.
Getting help
If any of these signs sound familiar, book an appointment with a dental prosthetist or dentist. They can assess your dentures and recommend whether a reline, repair or replacement is the right option for you.

Comfort is worth it
Your dentures should help you eat, speak and smile with confidence. If they no longer feel right, there is no need to put up with it. Recognising the signs early and seeking professional advice can help you stay comfortable and keep enjoying the foods and activities you love.
