How to Know When It’s Time to Replace Your Dentures
Dentures play an important role in helping you speak clearly, eat comfortably, and feel confident when you smile. But over time, changes in your mouth or natural wear and tear mean your dentures may not fit like they used to.
At Clinical Smiles in Sandringham, we help patients across Auckland recognise when it’s time to refresh their smile and upgrade to better-fitting dentures. Here are the most common signs to look out for:
1. Your dentures are loose or unstable
Gums and jawbone naturally shrink over time. If your dentures begin to slip when talking or eating, or if you find you need more adhesive than before, this is a sign they no longer support your mouth properly. Ignoring loose dentures can lead to sore spots and faster bone loss.
We may recommend a reline or, if the change is significant, new dentures made to your current anatomy.
2. You have discomfort or irritation
Dentures should not cause pain. If you’re experiencing mouth ulcers, gum irritation, or pressure points, your dentures no longer fit properly. Early attention prevents further complications.
3. Visible wear or damage
If denture teeth are worn down, chipped, or cracked, this affects:
your bite
speech clarity
smile aesthetics
long-term hygiene
A worn denture no longer provides proper function or confidence — replacement brings back a healthy, natural look.
4. Difficulty eating or speaking
If chewing feels harder than it used to, or if speech changes (like whistling or lisping) occur, your denture may no longer provide correct bite support.
Dentures should make life easier — not harder.
5. Changes in facial appearance
As bone reshapes and soft tissues relax over time, you may notice:
deeper wrinkles around your mouth
a sunken look in the cheeks
thinner lips
jaw or facial muscle fatigue
Fresh, well-fitting dentures restore facial support and youthful fullness.
How long should dentures last?
Most dentures last 5–7 years depending on:
Fit quality
Daily wear and denture care
Changes in oral tissues
Medical or lifestyle changes (e.g., weight loss)
We recommend an annual check-up so we can ensure they still support your oral health and confidence.
