At Eastport Dental in Mesa, Arizona, we see patients regularly who have been putting up with ill-fitting or worn dentures far longer than they should. The good news: most issues are very fixable. Here’s how to know what you’re dealing with.

First: Can the dentures be repaired, or do they need to be replaced?

Not every denture problem means starting over. In many cases, a repair or reline is all you need. Here’s the quick breakdown:

Usually repairable

• A crack from dropping your denture
• A broken clasp on a partial
• A loose fit from bone and gum changes
• Adding a tooth to an existing partial

Usually needs replacement

• Denture broken into two or more pieces
• Teeth worn down significantly
• Multiple issues where repairs cost more than a new appliance

7 signs your dentures need to be relined or replaced

Sign 1: They feel loose

Bone and gum tissue shrink over time. A reline may restore the fit.

Sign 2: They’re cracked

Minor cracks may be repairable. A complete break usually means replacement.

Sign 3: Teeth look worn down

Acrylic teeth wear over time. When they do, it affects both appearance and function.

Sign 4: A clasp is broken

Thin metal clasps on partials can break with daily use. Usually an easy fix.

Sign 5: You need a tooth added

If you’ve had a natural tooth removed, we can often add to your existing partial.

Sign 6: Repairs keep adding up

When the cost of ongoing repairs rivals a new appliance, replacement makes more sense.

Sign 7: Your denture is old

Most insurance plans cover a new denture every 5–7 years. You may already qualify. Contact us to find out!

What each dentures issue means — and what we do about it

Loose or ill-fitting dentures

After teeth are removed, your jawbone and gum tissue gradually shrink and change shape. This is completely normal, but it means the denture that fit perfectly a few years ago may not fit the same way today. When this happens, we can reline the inside of your plate with new acrylic, remolded to the current shape of your gums. The result feels like a brand new denture — without the cost of making one from scratch.

Cracked dentures

Dropping a denture on a hard floor is one of the most common causes of cracks. Depending on how severe the crack is, a repair may be possible — sometimes reinforced with a metal mesh or bar inside the acrylic for added strength. If the plate has broken into two or more pieces, a repair is unlikely to hold long-term, and a new denture is usually the better investment.

Worn-down teeth

The teeth on a denture or partial are made from acrylic resin — a durable material, but not as hard as natural teeth or dental crowns. Over years of chewing, they wear down. When that happens, it changes how your bite works and how your smile looks. At that point, a full replacement is usually the right call.

Broken clasps on partials

Metal clasps hook your partial denture onto your remaining natural teeth. They’re thin, and if you’re removing your partial multiple times a day (which you should be, to clean it after meals and before bed) they can eventually break. This is typically a straightforward repair.

Adding a tooth to an existing partial

If you have a partial and need to have a natural tooth removed, we can usually add a new tooth to your existing appliance rather than starting over. We match the shade and shape of the surrounding teeth so it looks like it was always there.

Repairs are becoming too costly

If your denture needs multiple fixes at once — new teeth, new clasps, a reline — the repair bill can start to approach what a new appliance would cost. In those cases, investing in a new denture that will last several more years often makes more financial sense than pouring money into ongoing repairs on an aging appliance.

Frequently asked questions

Will dental insurance pay for a new denture?

In most cases, yes — at least in part. Most dental insurance plans include a clause that covers a new denture every 5-7 years. If your current appliance is older than that, there’s a good chance you already qualify. We’re happy to check your benefits before your appointment so you know exactly what to expect before any work begins.

How do I know if my denture needs a reline or a full replacement?

The most common sign that a reline is needed is a loose fit — the denture shifts, slips, or doesn’t feel as secure as it used to. If the teeth are worn down, the plate is broken into pieces, or repairs are piling up, replacement is usually the better option.

How long do dentures typically last?

With proper care, a full denture typically lasts 5–10 years before needing replacement. Partials can last a similar amount of time, depending on how well the remaining natural teeth hold up. Regular checkups help us catch issues before they become bigger problems.

Can a completely broken denture be fixed?

If it’s broken into two or more pieces, usually not in a way that holds up long-term — even with reinforcement. In most cases of a complete break, a new denture is the more reliable and cost-effective solution.

How often should I have my dentures checked?

At least once a year. Even if your denture feels fine, your jawbone and gum tissue continue to change over time. Regular exams let us monitor the fit and catch wear or damage early.
