Denture or Appliance Additions

What Is a Denture or Appliance Addition?

A denture or appliance addition is a modification made to an existing dental appliance by adding a new component.

One common example is adding an artificial tooth to an existing denture following the loss or removal of a natural tooth. Depending on the appliance and the circumstances, other additions may also be possible.

The purpose of an addition is to modify an existing appliance to accommodate a particular change. It is different from making a completely new denture and is also different from a repair, which generally involves addressing damage or breakage to an existing appliance.

An addition is not appropriate for every appliance. Your dentist or dental team will need to assess the denture or appliance before confirming whether it can be modified.

When Might an Addition to a Denture Be Considered?

An addition may be considered when there has been a change involving your teeth or oral appliance and the existing denture may be capable of being modified.

For example, an artificial tooth may sometimes be added to an existing partial denture following the loss or removal of a natural tooth.

Other situations may require a different type of modification, depending on the appliance involved.

Before an addition is carried out, your dentist will consider:

• The condition of the existing denture or appliance
• The material from which it is made
• The design and construction of the appliance
• The position of the area requiring modification
• The condition of your gums and oral tissues
• Your bite and how the appliance interacts with the opposing arch
• Whether the existing appliance remains suitable
• Whether a new appliance may be more appropriate

An assessment helps determine whether modifying the existing appliance is a suitable approach.

Why Might an Existing Denture Need to Be Modified?

Your mouth can change over time, and your dental needs may change as well. For someone who wears a partial denture, the loss or removal of another natural tooth can alter the areas that need to be replaced.

In some circumstances, an addition to the existing denture may be considered. This can allow the appliance to be modified to reflect the new situation.

However, adding a tooth or another component does not necessarily address every change that has occurred. The fit, support and overall condition of the denture still need to be considered.

If the appliance is old, significantly worn, damaged or no longer fits appropriately, your dentist may discuss other options instead of, or in addition to, an appliance modification.

What Happens During an Assessment?

Your dentist will first examine your mouth and assess the existing denture or appliance.

The condition of the appliance will be considered alongside your oral health. Your dentist may look at:

• The fit of the appliance
• The condition of the denture base
• Any existing teeth or components attached to it
• The way the appliance contacts the opposing arch
• Signs of wear or damage
• The area where an addition is being considered

If a natural tooth has recently been removed, your dentist may also assess the healing area before deciding when and how an addition can be carried out.

The assessment provides an opportunity to discuss whether modifying the existing appliance is appropriate or whether a new denture or another treatment option should be considered.

How Is a Tooth Added to an Existing Denture?

If your dentist determines that an addition is appropriate, the existing appliance is assessed and prepared for modification.

Where a tooth is being added, the replacement tooth is selected and positioned as part of the planned modification. The denture may then be altered to accommodate the additional tooth.

The exact process depends on the type and construction of your denture. Some modifications may require laboratory work rather than being completed entirely during a single appointment.

Once the addition has been completed, your dentist can check the appliance in your mouth and assess its fit and relationship with the opposing teeth or appliance.

Adjustments may be required if the modified denture needs further attention.

Can Every Denture Be Altered?

No. Whether an existing denture or appliance can be modified depends on several factors.

The age and condition of the appliance, the material used, its design and the nature of the required addition can all influence whether modification is practical.

For example, an appliance that is significantly worn or damaged may not be suitable for further modification. Similarly, changes in the mouth may mean that a new appliance would be more appropriate.

Your dentist can examine your denture and explain the options available rather than assuming that an addition will be suitable.

What Happens After a Denture Addition?

A modified appliance may feel different from how it felt before the addition. Your mouth may also need some time to adapt to the change.

Your dentist will check the modified appliance and provide instructions about wearing and caring for it.

Pay attention to any changes in fit, movement, rubbing or discomfort. If you experience persistent irritation or difficulty using the appliance, contact your dental team for an assessment.

Do not attempt to glue, file, bend or otherwise modify the denture yourself. An alteration made without professional assessment could affect its fit or function.

How Should You Care for a Modified Denture?

A denture that has been modified still requires regular cleaning and appropriate care.

Your dental team can provide instructions specific to your appliance. These may include:

• Cleaning the denture regularly as advised
• Cleaning your natural teeth and gums carefully
• Paying attention to areas around the added component
• Handling the appliance carefully when inserting and removing it
• Using suitable denture-cleaning products
• Storing the appliance as recommended
• Attending routine dental examinations
• Reporting any changes in fit, damage or discomfort

If you have remaining natural teeth, maintaining their health remains important because they may interact with or provide support for the denture.

How Long Will a Denture Addition Last?

There is no fixed period for which a denture addition will remain suitable. Its condition can be affected by everyday use, the condition of the original appliance, changes in the mouth and the way the modified denture is cared for.

An addition may also be affected by future changes to the teeth or oral tissues.

Regular dental reviews allow your dentist to assess both your mouth and the modified appliance. If further changes occur, your dentist can discuss whether another modification, repair, reline, replacement or a different treatment option may be appropriate.
