What Are Dentures?

Dentures are removable appliances that replace some or all missing teeth and are made to fit an individual mouth.

Dentures are removable appliances made to replace missing teeth. A complete denture, often called a full denture, replaces all the teeth in the upper or lower jaw. A partial denture replaces one or more teeth while some natural teeth remain.

Both types include artificial teeth held in a base shaped to fit the mouth. The design and support can differ, so another person’s denture may not look or work exactly like yours.

What do dentures do?

Dentures fill spaces left by missing teeth. They can help with chewing, speaking, and appearance, although they do not feel exactly like natural teeth and usually take time and practice to use.

Dentures are only one category of tooth replacement. Bridges are generally fixed in place, while dentures are removable by the person wearing them. Dental implants are supports placed in the jaw and can hold a crown, bridge, or some types of denture. This overview of tooth-replacement options explains those categories without choosing one for you.

Full dentures and partial dentures

The simplest difference is how many teeth the denture replaces.

Complete or full dentures

A complete denture replaces all natural teeth in one arch—the upper jaw, lower jaw, or both. It rests over the gums and is shaped to work with the tissues and contours of the mouth.

Two timing terms often come up:

  • A conventional denture is made and placed after remaining teeth have been removed and the tissues have had time to heal.
  • An immediate denture is placed on the same day remaining teeth are removed. Because the mouth changes as it heals, an immediate denture commonly needs follow-up adjustments and may later need to be relined or remade.

These terms describe timing, not whether one design is best for a particular person.

Partial dentures

A removable partial denture replaces one or more missing teeth while natural teeth remain. Replacement teeth are attached to a base, which may include a metal framework, clasps, or other connectors. The design depends on the teeth being replaced and the structures available for support.

A partial denture also makes care of the remaining teeth especially important. The appliance and the natural teeth need separate, thorough daily cleaning.

Dentures that use implants

Some removable dentures connect to dental implants for added support or retention. The implants are placed in the jaw; the denture is the replacement that connects above them.

“Implant” and “denture” therefore describe different parts of the system. What Is a Dental Implant? explains that vocabulary in more detail.

How are dentures made and fitted?

A dentist first evaluates the mouth and discusses which teeth need replacement. Measurements, impressions, or a digital scan can record the shape of the mouth. The denture is then made from the plan and records, and the dentist checks its fit when it is placed.

Follow-up is a normal part of the process. A new denture may need adjustments as the wearer learns to use it or as the mouth heals. Over time, the gums and jaw can also change shape, so a denture that once fit well may become loose or uncomfortable.

An online guide can explain the categories, but it cannot determine which design will fit a particular mouth. That requires an examination and an individual treatment discussion.

What does the adjustment period feel like?

New dentures often feel awkward or bulky at first. Speaking and eating may take practice. Some people notice temporary extra saliva, minor irritation, or a sense that the denture is loose while the cheeks and tongue learn to work with it.

General adjustment tips include:

  • follow the wearing and removal schedule given by the dentist;
  • practice inserting and removing the denture as instructed;
  • begin with softer foods cut into small pieces;
  • chew slowly and use both sides of the mouth; and
  • practice saying difficult words or reading aloud.

Adjustment does not mean ignoring a persistent problem. A dentist can check pressure spots and make appropriate adjustments. Do not force a partial denture into place by biting down, and do not reshape or repair a denture yourself.

The basics of denture care

Dentures collect food, plaque, and stains, so they need daily care. A basic routine includes removing and rinsing the denture, gently brushing all its surfaces with a soft brush and a suitable nonabrasive cleanser, rinsing it thoroughly, and storing it safely when it is out of the mouth.

The rest of the mouth still needs care too. Clean the gums, tongue, cheeks, roof of the mouth, and any remaining natural teeth. Partial-denture wearers also need to clean around the teeth and areas that support the appliance.

Many people are advised to remove dentures at night, but instructions can differ after extractions or with a particular design. Follow the schedule given by the dental team. When a denture is out of the mouth, it generally needs to be kept moist and away from hot or boiling water, which can warp some materials.

When should a dentist check a denture?

Regular dental visits still matter when you wear dentures, even if you have no natural teeth. The dentist can examine the mouth and check whether the denture remains clean, stable, and appropriately fitted.

Arrange a dental check if:

  • the denture slips, clicks, or no longer feels secure;
  • soreness, rubbing, or irritation persists;
  • eating or speaking remains difficult;
  • the denture is cracked, worn, bent, or otherwise damaged;
  • the gums are very red or bleeding; or
  • bad breath continues despite regular cleaning.

These changes do not identify one cause on their own. A dentist can examine both the mouth and the appliance and explain whether an adjustment, repair, reline, replacement, or other care is reasonable.

Useful questions to ask

If dentures are being discussed, these questions can make the plan easier to understand:

  • Would this be a complete denture or a partial denture?
  • What would support and hold it in place?
  • Is it conventional, immediate, or connected to implants?
  • What should I expect while eating and speaking at first?
  • When should I wear it, remove it, and return for adjustments?
  • How should I clean this specific denture and the rest of my mouth?
  • Which changes in fit or comfort should prompt a call?

The takeaway

Dentures are removable replacements for missing teeth. Complete dentures replace all the teeth in an upper or lower jaw, while partial dentures replace one or more teeth alongside remaining natural teeth. Learning to use them takes time, and daily cleaning, mouth care, follow-up adjustments, and regular dental checks all help keep the appliance useful and the mouth comfortable.
