If you are getting dentures for the first time, or replacing an older set, one of the first decisions you will face is which material to choose.
The two most common options in the UK are acrylic and cobalt chrome, and each has its own strengths. The right choice depends on your mouth, your budget, whether you need a full or partial denture, and what matters most to you day to day.
This guide compares chrome and acrylic dentures side by side. We look at what each type is, how they are made, how they differ in fit, comfort, durability and appearance, what they cost, and whether chrome dentures are safe.
By the end you should have a much clearer idea of which option suits your situation, and our team is always happy to talk it through with you in person, whether you need denture repairs or partial dentures.
What are acrylic dentures?
Acrylic dentures are made from a dental acrylic resin, a hard-wearing plastic known as PMMA (Polymethyl methacrylate).
The base is coloured to match your gums, and the replacement teeth are set into it to create a natural-looking result. This is the most widely used denture material in the UK, and dentures provided on the NHS are typically made from acrylic.
Acrylic can be used for both full and partial dentures. A full acrylic denture replaces a complete arch of teeth and rests on your gums, held in place by a combination of suction and the natural contours of your mouth. Acrylic partial dentures replace one or more missing teeth and sit alongside your remaining natural teeth, often using small clasps to help hold them steady.
Because acrylic needs a certain thickness to stay strong, these dentures tend to be a little bulkier than metal-based ones, and an upper acrylic denture usually covers more of the roof of the mouth. For many people this is barely noticeable after a short settling-in period, and acrylic remains a comfortable, dependable and affordable choice.
A note on flexible dentures
You may also come across flexible dentures, sometimes grouped in with acrylic options. These are made from a softer, more pliable material rather than rigid acrylic resin, and they use gum-coloured flexible clasps instead of metal ones. They can be a discreet and comfortable choice for certain partial denture cases, and our team can advise whether they might suit you.
What are chrome dentures?
Chrome dentures are built around a lightweight framework made from a cobalt chrome metal alloy. This framework forms a thin, strong base, onto which gum-coloured acrylic and natural-looking teeth are added. Because the metal is so strong, the base can be much thinner than an all-acrylic one, which many wearers find more comfortable and less intrusive.
A cobalt chrome denture is most often used as a partial denture. The framework is designed with small rests that sit on your natural teeth, along with clasps that grip them discreetly to hold the denture firmly in place. This means the chewing forces are shared by your natural teeth rather than resting entirely on your gums, which is kinder to the soft tissue underneath.
People sometimes ask about full chrome dentures. Chrome is generally reserved for partial dentures, but a metal base can also be used for a full upper denture, giving a thinner, stronger palate and allowing you to taste and feel the temperature of food more easily. Whether this is suitable depends on your individual case, which is something we can assess at your consultation.
How chrome and acrylic dentures are made
Both types begin the same way, with impressions and measurements of your mouth so the denture can be crafted to fit you precisely. From there, the process differs.
An acrylic denture is shaped from dental acrylic resin, with the teeth carefully positioned and the base finished to blend in with your gums. A chrome denture requires an extra stage, because the metal framework is cast first, then finished by hand before the acrylic and teeth are added. This careful chrome denture design is what gives the finished piece its strength, slim profile and secure grip.
At Kevin Manners Denture Clinics, every denture is designed and handcrafted by our Clinical Dental Technician, so the fit and finish are tailored entirely to you.
Chrome vs acrylic dentures: the key differences
The table below gives you a quick overview of how cobalt chrome and acrylic dentures compare across the things that matter most. We explain each point in more detail underneath.
| Feature | Chrome (Cobalt Chrome) | Acrylic |
|---|---|---|
| Main use | Mostly partial dentures | Full and partial dentures |
| Support | Shared by your natural teeth | Rests mainly on the gums |
| Thickness | Thin and slimline | Bulkier, more palate coverage |
| Durability | Very strong and long-lasting | Durable but less rigid |
| Typical lifespan | Around 10 to 15 years or more | Around 5 to 8 years |
| Adjustments | Harder and costlier to alter later | Easy to adjust, reline and add to |
| Cost | A higher investment | The more economical option |
Fit and stability
Chrome dentures are known for a precise, secure fit. Because the framework rests on your natural teeth and uses tailored clasps, a chrome partial denture tends to feel very stable and stays put well. Acrylic dentures are also comfortable and functional when properly made, though a partial acrylic denture relies more on its clasps and the surrounding teeth and gums for support.
Comfort and feel
The slim profile of a chrome denture is one of its biggest attractions. With less bulk and less coverage of the palate, many wearers adapt quickly and find they can taste and enjoy their food more fully. Acrylic dentures are thicker by necessity, so they can feel more noticeable at first, but the vast majority of people settle in comfortably with a little time.
Durability and lifespan
Cobalt chrome is extremely strong, which is why chrome dentures often last well over a decade with good care.
Acrylic is hard-wearing too, but a little more prone to wear and the occasional crack, so people often ask how long acrylic dentures last. As a general guide, a well-cared-for acrylic denture lasts around five to eight years before it may need replacing, though this varies from person to person.
You can read more about how long dentures last and when to replace them in our dedicated guide.
Appearance
Both materials can produce a natural, attractive smile. The one thing worth bearing in mind with chrome is that the metal clasps can occasionally be visible, depending on where your missing teeth are and how the denture is designed.
A skilled technician will position the clasps as discreetly as possible, and in many cases they are barely noticeable. Acrylic and flexible options avoid metal clasps altogether, which some people prefer for front teeth.
Cost
Acrylic is generally the more affordable choice, which is one reason it is so widely used. Chrome dentures carry a higher price because of the extra materials and the additional laboratory work involved in casting the framework.
Private prices vary depending on the design and your individual needs. You can see our own denture pricing at Kevin Manners Denture Clinics for a clear guide, with dentures starting from £595.
Adjustments and repairs
Acrylic dentures have a practical advantage here. They are relatively straightforward to adjust, reline or add teeth to, which makes acrylic a sensible choice if you expect to lose further teeth in future, or if you want an immediate denture while your mouth heals.
Chrome dentures are more involved to alter once made, because of the fixed metal framework. Whichever you choose, our repairs and alterations service is here to keep your dentures in good shape.
Are chrome cobalt dentures safe?
This is a very common and understandable question. The short answer is yes. Cobalt chrome alloys have been used in dentistry and medicine for many years and are considered biocompatible, meaning they are well tolerated by the body. The same family of metals is used in a range of medical devices, which speaks to their safety record.
Chrome denture side effects are uncommon. A small number of people have a sensitivity or allergy to certain metals, such as cobalt or nickel, and in those rare cases a metal denture may not be the best fit. If you know you have a metal allergy, do mention it, and we can recommend a suitable alternative such as an acrylic or flexible denture.
Aside from that, the main things people notice are cosmetic, like the occasional visible clasp, rather than anything to do with health.
Chrome dentures: the pros and cons
To help you weigh things up when deciding what type of denture to get, here are the main advantages and disadvantages of chrome dentures.
The benefits include:
- a thin, lightweight and comfortable design
- excellent strength and a long lifespan
- a secure, stable fit supported by your natural teeth
- less coverage of the palate, so food tastes more natural
- kinder to the gums, as chewing forces are shared with your teeth
The main chrome denture disadvantages are:
- a higher cost than acrylic
- metal clasps that may sometimes be visible
- less easy to adjust or add to later
- you need enough healthy natural teeth to anchor the framework
Acrylic dentures: the pros and cons
Acrylic has its own set of strengths and limitations. The benefits include:
- a more affordable price
- suitable for both full and partial dentures
- easy to adjust, reline and add teeth to
- a good option for immediate dentures and healing gums
- no metal clasps needed on the more discreet designs
The trade-offs to be aware of are:
- a bulkier feel and more palate coverage
- a slightly shorter lifespan than chrome
- more reliance on the gums for support with partial dentures
So, which should you choose?
There is no single right answer, because the best option genuinely depends on you. As a broad guide, a cobalt chrome partial denture is often a wonderful choice if you have several healthy natural teeth to anchor it and you want a slim, strong and long-lasting result. Acrylic tends to suit those who want a more economical option, who need a full denture, or who may need adjustments and additions down the line.
If you are asking whether chrome dentures are better than acrylic, the honest answer is that neither is simply better than the other.
They are different tools for different needs, and the ideal choice comes down to your teeth, your gums, your budget and your priorities. This is exactly the kind of decision our team helps patients make every day, and we will never push you towards a more expensive option than you need.

Caring for your dentures, whichever you choose
Both chrome and acrylic dentures last longer and stay more comfortable when they are looked after well. A simple daily routine of gentle cleaning, rinsing after meals and soaking overnight keeps them fresh, and it is just as important to keep your gums and any natural teeth clean too.
Regular check-ups allow us to keep an eye on the fit and make small adjustments before they become a nuisance. Our guide to cleaning your dentures covers the essentials, and the Oral Health Foundation also offers trusted, independent advice on denture care.
