What are removable dentures?
Removable dentures replace missing teeth and can be taken in and out by the patient. They aim to support chewing, speech and appearance where teeth are missing. Unlike a fixed bridge or an implant-supported fixed restoration, the denture can be removed from the mouth in daily use.
This page focuses on conventional complete and partial removable dentures. Removable systems retained by implants are a separate planning topic; see Implant-Supported Removable Prostheses.
Complete versus partial dentures
A complete denture replaces all teeth in one jaw. Upper and lower jaws may be planned separately; treating both jaws is not the same scope as treating one jaw.
A partial denture replaces missing teeth when some natural teeth remain. The health and position of those teeth, and the denture design, are assessed together. Care of remaining teeth matters as much as care of the denture.
Where the denture rests and how it stays in place
A conventional complete denture is supported mainly by the oral tissues (gums and jaw ridge; the palate also plays a role in the upper jaw). Retention and stability vary with the person, anatomy and how the denture borders fit.
In a partial denture, support may be shared across remaining teeth, oral tissues, or both, depending on the design. Not every partial denture distributes support in the same way.
Holding conditions can differ between the upper and lower jaws. Less palate support in the lower jaw may mean a different settling-in period; that does not mean treatment is unsuitable.
Metal frameworks, acrylic and retention methods
For partial dentures, the base or framework material and the retention method are separate choices. A denture may be mainly acrylic (plastic) or have a metal framework. Metal-framework dentures can be planned thinner in many cases; they are not suitable for everyone.
Clasps that rest on remaining teeth may provide retention. In the tooth-supported partial designs described on this page, precision attachments (sometimes called “slide” attachments in everyday language) may be used; they differ from clasps and often need crowns or preparation on supporting teeth. There is no universal rule that precision attachments can only be used on natural teeth; implant-supported removable options are planned separately and covered on the linked page.
The phrase “metal-supported removable denture” usually refers to the framework material; it does not by itself decide between clasps and precision attachments.
Impressions, try-in, fitting and adjustments
The pathway typically includes impressions or digital records, jaw-relation records, a tooth set-up try-in, and delivery. Appearance, speech and bite are reviewed together at try-in.
After delivery, review visits may be needed for pressure spots, sore areas, or speech and chewing concerns. If pain is severe or soreness persists, do not force the denture—contact the clinic. Do not file the denture yourself, bend clasps, or try to repair it with household glue; that can damage the denture and the mouth.
An immediate denture is made to be fitted straight after extractions. Not every temporary denture is immediate, and not every immediate denture is only for short-term use. As tissues change during healing, an immediate denture may loosen; relining or remaking may be needed. For new dentures after extractions, follow your clinician’s plan for wearing and removing them.
Getting used to dentures
At first the denture may feel bulky or foreign; saliva may increase and speech may change for a while. How long settling takes varies from person to person. Starting with soft foods cut into small pieces and chewing on both sides can help. Sticky or very hard foods can be difficult early on.
Mild sore spots can often be eased with adjustments. If pain is severe, remove the denture and contact the clinic.
Fit changes over time, relining and repairs
After extractions or over years, gums and jaw ridges can change shape. A denture that once fitted well may loosen or start to rub. Options can include a soft-tissue surface refresh (relining), laboratory repair, or a new denture—these are not the same procedures.
Relining re-adapts the tissue-facing surface of the existing denture. Repair or remaking for fractures, cracks, lost teeth or a damaged framework is assessed separately.
Denture adhesives may add retention when your clinician advises them. They should not be treated as a lasting fix for a poor fit or as a substitute for clinical review. If the denture will not stay in place without adhesive, or you need to reapply it repeatedly during the day, its fit should be checked.
Care
Clean the denture and the tissues in your mouth every day. On remaining natural teeth, keep using fluoride toothpaste and clean between the teeth. Do not use abrasive toothpaste on the denture surface; use a soft brush daily and a cleanser suited to the material. For dentures with metal parts, ask about product compatibility. Hot or boiling water can distort the denture.
Denture cleanser tablets or solutions are used outside the mouth; rinse the denture thoroughly before putting it back in. Do not rinse your mouth with cleanser; do not swallow cleanser or leave it in the mouth.
Unless your clinician gives different instructions, take the denture out at night. After extractions, the early wearing plan for a new denture may differ—follow written advice. Leaving a denture dry can change its shape; store it according to the material and clinician or manufacturer guidance. One solution or soak time does not suit every denture.
Even when no natural teeth remain, reviews are still needed for tissue health, denture fit and possible infection signs.
Implant-supported removable options
For some patients, implant-supported removable dentures may be considered to help retention. That pathway is a separate surgical and prosthetic plan from conventional complete or partial dentures. For comparison see Implant-Supported Removable Prostheses, and for bar-retained systems see Bar-Retained Implant Prostheses. Fixed implant-supported options are covered on Implant-Supported Fixed Prostheses.
