Denture Rebase and Repairs

Dentures are an acceptable method for replacing missing teeth, but they are not meant to last forever. Sooner or later, your dentures will need to be repaired, which may involve rebasing.

What is a rebase?

Rebasing is a type of denture repair involving the replacement of the denture base. Dentures are expected to be replaced within about seven years to ensure that they fit properly and maintain function and appearance. Before replacement is necessary, you should have your dentures looked at every year or two to determine if repairs are needed.

When would my dentures need to be rebased?

Dentures are relined to adjust their fitting. Rebasing is a more involved adjustment entailing denture retrofitting to replace the acrylic base using new acrylic material. 

Rebasing offers greater denture stability without altering the denture teeth. A denture rebase can be performed whenever the denture teeth are not compromised relative to the base material.

Reasons to recommend include:

  • Broken or damaged denture
  • Weekend acrylic base
  • Altering a temporary denture to a permanent denture

Rebasing Process

To have your dentures rebased, your dentist will create a new impression. They will completely remove the old acrylic. Denture rebasing alters both the outside and inside of the denture to provide a correct fit. By consulting with your dentist, you can learn if you need a rebase or reline.

If a Denture Breaks

You can be tempted to save money by repairing a damaged denture yourself, but it is not recommended. Leave this type of work to dental professionals who have more experience with denture repair. Your dentures can be repaired at the dental office, and some repairs can even be performed on the same day.

Different Types of Denture Repairs

Here are a few common types of denture repairs and maintenance:

  • Denture adjustment: Your dentures can be adjusted to prevent discomfort and irritation.
  • Denture relining: Involves altering the surface area resting on the oral cavity tissues.
  • Denture rebasing: Transferral of teeth from an old denture using a new acrylic base. 

When To Contact Your Dentist 

Your dentures should fit well and be comfortable. If your dentures slip or completely fall out of your mouth, or you have to change your diet because of changes to your dentures, it’s time to contact your dentist for an appointment.
