Denture Reline and Repair

What Is a Denture Reline?

A denture reline involves adding or modifying material on the fitting surface of an existing denture to improve how it corresponds with the tissues supporting it.

The shape of the mouth can change over time, which may affect the fit of a denture. A denture that once fitted well may become less secure or feel different during use.

A reline may be considered when the existing denture remains suitable in other respects but its fitting surface needs modification.

However, a reline is not appropriate for every loose or poorly fitting denture. The overall condition, age, design and function of the appliance need to be assessed first.

What Is a Denture Repair?

A denture repair involves addressing certain forms of damage to an existing appliance.

Damage can occur for a variety of reasons, including accidental dropping, everyday use or changes affecting the denture. The type of repair required depends on the nature and extent of the damage.

Examples may include certain fractures, breaks or damage to components of a denture. Whether a repair is possible depends on the appliance and the damage involved.

Your dentist can examine the denture and explain whether it can be repaired or whether replacement may be more appropriate.

What Is the Difference Between a Reline and a Repair?

Although both involve an existing denture, they address different problems.

A reline primarily concerns the surface of the denture that sits against the tissues in your mouth. It may be considered when changes in the mouth have affected the fit of an otherwise suitable appliance.

A repair addresses damage to the denture itself, such as a break or fracture where repair is considered possible.

In some situations, an appliance may have both a fit issue and physical damage. Your dentist will assess the denture as a whole before deciding what treatment may be appropriate.

If the denture is significantly worn, damaged or no longer suitable, replacing it may need to be considered instead.

Why Might a Denture Need a Reline?

Your mouth is not completely unchanged after a denture has been made. The tissues supporting the appliance can alter over time, which may affect the relationship between the denture and your mouth.

You may notice changes such as:

• The denture feeling less secure
• Increased movement while speaking or eating
• Changes in how the denture contacts the mouth
• Areas of rubbing or irritation
• A change in how the denture feels compared with when it was first fitted

These symptoms do not necessarily mean that a reline is required. A dental assessment is needed to identify the underlying issue.

Your dentist will consider the fit of the appliance and its overall condition before recommending a reline.

Why Might a Denture Need Repair?

A denture can become damaged through accidental impact, everyday handling or normal use.

You may notice:

• A visible crack or fracture
• A broken section of the denture
• Damage to an artificial tooth
• A component becoming detached
• Difficulty inserting or removing the appliance following damage

A damaged denture should be assessed rather than repaired at home. Household adhesives and other DIY repair methods may interfere with the materials used in the denture and can make professional repair more difficult.

Your dentist can inspect the damage and advise whether a repair is possible.

What Happens During a Denture Assessment?

Your dentist will examine both your mouth and the denture.

The assessment may consider:

• The condition of the denture
• Its fit and stability
• The fitting surface
• Any cracks, fractures or damaged components
• The condition of the tissues underneath the denture
• Changes in your mouth since the denture was made
• The relationship between the denture and opposing teeth or another denture
• Whether the existing appliance remains suitable

The assessment helps determine whether the problem is related to the fit, physical damage or another factor.

Your dentist can then explain the available options, which may include a reline, repair, replacement or another form of treatment.

What Happens During a Denture Reline?

If a reline is considered suitable, the fitting surface of the denture is modified to correspond more closely with the current shape of the supporting tissues.

Depending on the type of reline and the treatment plan, the process may involve taking an impression using the existing denture before the appliance is modified.

The denture may require laboratory processing before it is returned for fitting. Your dentist will check the modified appliance and assess its fit in your mouth.

The exact process can vary depending on the denture and the type of reline being carried out.

What Happens During a Denture Repair?

The repair process depends on the type and extent of damage.

Your dentist will first examine the appliance and determine whether repair is feasible. If a repair is appropriate, the denture may need to be sent to a dental laboratory or undergo a specific repair procedure.

Once the work has been completed, the appliance can be assessed to ensure that the repaired area and overall fit are appropriate.

If the damage has resulted in changes to the way the denture fits or functions, your dentist may recommend additional assessment or discuss whether a replacement appliance should be considered.

How Should You Look After Your Denture After a Reline or Repair?

Your dentist will provide care instructions based on your particular appliance and the work carried out.

General denture care may include:

• Cleaning the denture regularly using the recommended method
• Cleaning your gums, tongue and any remaining natural teeth
• Handling the appliance carefully during removal and insertion
• Storing the denture as advised when it is not being worn
• Using suitable denture-cleaning products
• Avoiding attempts to repair or modify the appliance yourself
• Attending regular dental reviews
• Contacting your dental team if problems with fit or damage return

If you have natural teeth remaining, these should continue to receive regular brushing and dental care.

When Might a New Denture Be More Appropriate?

A repair or reline is not always the most suitable solution. An existing denture may have significant wear, damage or changes in fit that make continued modification unsuitable.

Your dentist will consider the condition and age of the appliance, your oral health and how the denture functions before recommending the next step.

If a replacement is more appropriate, your dentist can explain the available options and discuss the process involved.
