What Is a Copy Denture, and When Would You Need One?

If you have worn the same denture for years, you will know how much it becomes part of you. Your tongue, cheeks and lips have learned its shape. You speak and eat with it without a second thought.

So when that denture starts to wear out, the idea of starting again from scratch can be daunting. A brand-new design can feel bulky and unfamiliar, and some people take months to settle into one.

This is where a copy denture comes in. Below, we explain what a copy denture is, when you might need one, and why spare dentures are worth thinking about.

What is a copy denture?

A copy denture is a new denture made by replicating the shape of one you already wear. It is sometimes called a replica or duplicate denture.

Rather than designing a new denture from a blank canvas, your dentist uses your existing one as the template. The outer shape, the position of the teeth and the way it sits against your lips and cheeks are all reproduced. The parts that have worn out are then renewed.

In practice, that usually means:

• The familiar shape stays. The polished outer surfaces your mouth has adapted to are kept as close to the original as possible.
• The fit is refreshed. A new impression captures how your gums look today, so the denture sits snugly again.
• The teeth are renewed. Worn, flattened or stained teeth are replaced with new ones set in the same positions.

The result is a denture that feels like your old one, only fresher, more secure and better looking.

How is a copy denture made?

A copy denture usually takes fewer appointments than a conventional new denture, because much of the design work has already been done. The exact steps vary from person to person, but the process generally looks like this:

1. Assessment. Your dentist examines your mouth and your current denture, and talks through what you like about it and what you would change.
2. Copying your denture. A mould is taken of your existing denture to create a replica template. This is quick, and you keep wearing your own denture throughout.
3. New impressions and bite record. The template is used to take an accurate impression of your gums and to record how your teeth meet.
4. Try-in. You try a trial version so you and your dentist can check the look, fit and bite before anything is finalised.
5. Fitting. Your finished copy denture is fitted, with a review afterwards to make any small adjustments.

Small improvements can be built in along the way. Your dentist might restore lost height in the bite, brighten the tooth shade slightly or tidy up the edges, all without changing the overall feel.

When do you need a copy denture?

A copy denture suits people who are broadly happy with their current denture but can tell it is past its best. Common signs include:

• Your denture has become loose. Gums and jawbone change shape over time, so a denture that once fitted well can start to slip or rock.
• The teeth are worn down. Flattened teeth make chewing harder work and can change the way your face is supported.
• The acrylic looks tired. Staining, hairline cracks and a dull finish are all signs of an ageing denture.
• You rely on fixative more than you used to. Needing more adhesive to feel secure often points to a fit that needs renewing.
• You have struggled with new dentures before. If a previous replacement never felt right, copying the one you got on with is often the gentler route.
• You want a back-up. A spare set made from your current denture means you are never caught without teeth.

Copy dentures are especially helpful for people who have worn the same denture for many years. The longer you have had a denture, the harder it can be to adapt to a different shape. Keeping things familiar makes the change far easier.

They can also be a kind option for anyone who finds dental visits tiring, as the process tends to be shorter and simpler.

Spare dentures: why a back-up set is worth having

Dentures get dropped in the sink, left in hotel rooms and chewed by the dog. A repair takes time, and a replacement takes longer. In the meantime, you may be left without teeth.

Spare dentures take that worry away. A spare is useful if:

• your main denture breaks or needs to go away for repair
• you travel often, or are heading off on holiday
• you have an important occasion coming up and want peace of mind
• you care for someone whose dentures are easily mislaid, for example in hospital or a care home

Because a spare is copied from the denture you already wear, it should feel familiar from the moment you put it in.

One thing to bear in mind is that your mouth keeps changing. A spare that sits in a drawer for years may not fit as well as it did on day one. Bring it along to your check-ups so your dentist can make sure it is still up to the job, and ask how best to store it between uses.

When is a copy denture not the right choice?

A copy is only as good as the denture it is based on. If the original has never been comfortable, copying it will simply reproduce the same problems.

A different approach may suit you better if:

• you have never liked the look or feel of your current denture
• the bite has always felt wrong
• the denture is badly broken or has been repaired many times
• you have lost more teeth, or your mouth has changed a great deal since it was made
• you would like a more secure solution, such as a denture held in place by dental implants

In these cases, a newly designed denture or an implant-retained denture is likely to give you a better result. If you have been searching for dentures Edinburgh and are not sure where to begin, our dentures page sets out the options for replacing some or all of your teeth.

Frequently asked questions

Will a copy denture feel exactly the same as my old one?

It should feel very familiar, though not identical. The fit will be tighter and the teeth will be sharper, so chewing often feels more efficient. Most people settle in within days rather than weeks.

Do I have to go without my denture while the copy is made?

No. The mould of your existing denture is taken during your appointment, and you leave wearing it as normal.

Can partial dentures be copied?

In many cases, yes. It depends on the design of your partial denture and the health of the teeth that support it. Your dentist will advise after an examination.

How long does a copy denture last?

With good care and regular check-ups, a well-made denture typically lasts for many years. Your mouth will continue to change, so the fit should be reviewed from time to time.

Is a copy denture the same as a reline?

No. A reline only renews the fitting surface of your existing denture. A copy denture is a completely new denture, with new teeth and new acrylic, built to the familiar shape.
