If you are missing teeth, dentures are one of the most common and affordable ways to replace them. The first decision is usually between a full denture and a partial denture, and the answer depends on one simple thing: whether you still have natural teeth in that jaw. This guide explains the difference, the materials involved, roughly what each costs across the market, and how to weigh dentures against fixed alternatives.
Key takeaways
- A full denture replaces all the teeth in an arch when none are left.
- A partial denture fills the gaps when some healthy natural teeth remain.
- Partials clip onto the remaining teeth, which makes them more stable than a full denture.
- Both come in acrylic and slimmer metal-framed or flexible versions.
- Implants can be added later to make either type far more secure.
The one question that decides it
The choice between full and partial comes down to whether there are sound natural teeth to build around. If a jaw has no teeth left, a full denture is the denture option. If healthy teeth remain, a partial denture is almost always preferred, because keeping your own teeth gives the denture something to grip and helps preserve the jawbone. Dentists generally try to retain natural teeth wherever they can rather than removing them to fit a full denture.
Full dentures
A full, or complete, denture replaces an entire arch of teeth and rests on the gums and underlying bone. The upper denture covers the palate, which helps it stay in place by suction. The lower denture sits like a horseshoe and has less to grip, which is why lower full dentures are the ones people most often find loose. Full dentures are usually made after any remaining teeth are removed and the gums have healed, although an immediate denture can be fitted on the day of extraction as a temporary measure.
Partial dentures
A partial denture fills one or more gaps while clipping around the natural teeth that remain. It usually has small clasps that grip nearby teeth, which makes it noticeably more stable than a full denture. Beyond appearance and chewing, a partial helps stop the remaining teeth drifting into the gaps. Partials suit people who have lost several teeth but kept others in good condition.
Materials and types
| Type | What it is | Best for |
|---|---|---|
| Acrylic full or partial | Pink acrylic base with denture teeth | Affordable, easy to adjust and add to |
| Metal-framed partial | Slim cobalt-chromium frame with acrylic and teeth | Stronger, thinner, more comfortable long term |
| Flexible partial | Bendable gum-coloured material, no metal clasps | Discreet clasps, lightweight feel |
| Implant-retained | Denture that clips onto implants | Maximum stability, see overdentures |
If a loose denture is the worry, adding implants converts either type into a far more secure implant-retained overdenture.
What they cost
Across the Australian market, a single-arch acrylic denture typically runs in the high hundreds to low thousands, metal-framed partials cost more, and implant-retained options cost more again. The exact figure depends on the material, the number of teeth, and any extractions or implants needed. We do not list our own prices here.

Living with dentures
New dentures take a couple of weeks to get used to as the cheeks, tongue and muscles adapt. Start with soft foods, practise speaking at home, and expect a few minor adjustments early on. Clean them daily, take them out overnight to rest the gums, and have the fit checked over time, because gums shrink and a denture that was snug can loosen and need a reline. Our guide to denture care and relines walks through the upkeep.
Dentures versus fixed options
Dentures are removable and the most affordable way to replace teeth, but they are not the only way. Bridges and implants are fixed and more stable, at a higher cost. For a full comparison, see implant versus bridge versus denture and types of dental bridges.
Frequently asked questions
Can I have a partial denture if I have only lost one tooth?
You can, though for a single gap a bridge or an implant is often preferred. A partial makes more sense when several teeth are missing.
Are partial dentures more stable than full dentures?
Generally yes, because they clip onto your remaining natural teeth for support rather than resting only on the gums.
How long do dentures last?
Often five to ten years, but they usually need a reline sooner as the gums change shape. Regular checks keep the fit comfortable.
Will a denture stop my other teeth moving?
A partial denture helps hold the remaining teeth in position and stops them drifting into the gaps, which is one of its quiet benefits.
Can I sleep with my dentures in?
It is best to take them out overnight. This rests the gums and lowers the risk of irritation and fungal infection.
The takeaway
The full-versus-partial choice is mostly decided by whether you still have healthy natural teeth to build around. Partials are more stable and help protect remaining teeth, while full dentures replace a whole arch and can later be secured with implants.
