Dentures don’t last forever. Over time, your gums and jawbone change shape — and so do the dentures themselves. Knowing when to replace them can save you years of discomfort. Here are the five most common signs to watch for.
1. They Don’t Fit Like They Used To
If your dentures feel loose, rock when you speak or chew, or you find yourself using more denture adhesive just to keep them in place, the fit has changed. This happens naturally as your jawbone resorbs (shrinks) over time in the absence of tooth roots. A poorly fitting denture isn’t just uncomfortable — it can cause sore spots and affect your nutrition if eating becomes difficult.
2. They Look Worn or Discoloured
Denture teeth wear down over years of use, just like natural teeth. If your bite feels different, your teeth look noticeably shorter, or the colour has changed despite regular cleaning, the dentures may be past their best. Worn teeth can also affect your bite and put strain on your jaw joints.
3. You Have Persistent Sore Spots
The occasional sore area after a new denture or adjustment is normal. But if you’re regularly getting sore spots, ulcers or irritation under your dentures, something isn’t right. This could indicate the denture base no longer matches your gum shape — a reline or new denture may be needed.
4. They’re Cracked or Repaired Multiple Times
A single repair is fine. But repeatedly repairing the same denture, or noticing multiple cracks, is a sign that the material has reached the end of its useful life. Dentures that have been repaired several times can also harbour more bacteria in the cracks.
5. It’s Been More Than 7–10 Years
Even if your dentures still seem okay, the general guideline is to consider replacement after 7–10 years. Materials degrade, your mouth changes, and modern dentures are significantly better than those made a decade ago in terms of aesthetics and comfort.
If any of these sound familiar, book a free consultation at Cotswold Denture Clinic in Poulton, near Cirencester. Simon Miles will assess your existing dentures and give you an honest opinion on whether a reline, repair or full replacement is the right next step.
Well-made private dentures typically last 7–10 years with good care, though your mouth will change over that time and adjustments may be needed sooner. NHS dentures may need replacing more frequently.
Yes — minor cracks or a single broken tooth can often be repaired. Our denture repairs service at Cotswold Denture Clinic can often be completed same-day. However, extensively repaired or very old dentures are usually better replaced.
A reline adds new material to the fitting surface of your existing denture to improve the fit without making a completely new one. It’s less expensive than replacement and suitable if the teeth themselves are still in good condition.
