Loose dentures: why they slip and what you can do
Dentures that move when you eat, talk or laugh are one of the most common complaints we hear. The good news: there's usually something that can be done.
Medically reviewed by Dt. Hüseyin Yavuz Özbek, implant surgeon · Updated October 2026Dentures usually become loose because your gums and jawbone slowly shrink and change shape after teeth are lost. The NHS advises seeing a dentist if your dentures click, slip or no longer fit. Depending on the cause, the fix may be an adjustment, a reline, a new denture, or a denture that clips onto two to four implants.
Why dentures become loose
When teeth are lost, the bone that held them slowly shrinks, and the gums change shape with it. A denture made to fit your mouth a few years ago may not fit it today. The NHS explains that dentures may become loose as your gums and jawbone shrink or change shape as you get older, and they can also become worn or damaged over time.
Other things that can make dentures feel loose:
- weight loss or illness
- a dry mouth, which reduces suction
- worn teeth on the denture, which change your bite
- a crack or repair that has altered the fit
When to see a dentist
The NHS says to see a dentist if:
- your dentures click when you're talking
- your dentures slip, or no longer fit properly
- your dentures are causing pain
- your dentures are worn or damaged
- you have very red or bleeding gums, or bad breath
Loose dentures aren't just annoying. If they rub, they can cause sore spots and infections, and make eating and speaking harder.
Your options, from simplest to most involved
| Option | What it involves | Good for |
|---|---|---|
| Adjustment | Your dentist smooths or tightens parts of the denture. | Small rubbing spots, loose clasps on a partial denture |
| Reline | A new layer is added to the fitting surface to match your gums now. | A denture that's in good condition but no longer fits |
| New denture | A new denture made to your mouth's current shape. | Old or worn dentures, often after five to eight years |
| Adhesive | A cream or powder that helps a well-fitting denture stay put. | Extra confidence, not a fix for a poor fit |
| Clip-on denture | Two to four implants are placed and the denture clips onto them. | Lower dentures that never stay in, however well made |
On the NHS, small adjustments to dentures are a Band 1 treatment, and more extensive work such as relining is a Band 2 treatment. A new denture is Band 3.
When implants are worth considering
If you've had well-made dentures relined or replaced and they still won't stay in, especially the lower one, it may be time to look at implants. Even two implants can make a big difference to a lower denture.

Our honest view as a clinic: many loose dentures can be fixed with a reline or a new denture from your local dentist. Try that first. If it hasn't worked, we're happy to talk you through what implants could do. Ask us on WhatsApp →
Common questions
Why are my lower dentures looser than my upper ones?
Upper dentures cover the roof of the mouth, which gives more suction. A lower denture sits on a narrower ridge with the tongue moving around it, so it has much less to grip. That's why lower dentures are the most common reason people consider implants.
Is it safe to use denture adhesive every day?
Adhesive can help a well-fitting denture feel more secure, but it isn't a fix for a denture that no longer fits. If you need more and more adhesive, see your dentist. Follow the instructions on the product.
What is a denture reline?
A reline adds a new layer to the fitting surface of your denture so it matches the current shape of your gums. It's often quicker and cheaper than a new denture.
Can I just get a new denture?
Yes, and if your denture is several years old that may be all you need. The Oral Health Foundation says dentures often need replacing every five to eight years because your mouth changes shape.
