Broken Denture? You Might Need A Denture Rebase

Rebasing is the process of adding a new base or foundation to existing dentures. It is done to improve the fit of ill-fitting dentures and make them look and feel more comfortable. Rebasing can also be used to prevent dentures from breaking due to cracks or breaks.

The decision to rebase your dentures should be made by you and your dentist together. In some cases, rebasing may not be the best option for you. For example, if your dentures are severely damaged, it may be better to have them replaced entirely.

Denture Repair: Rebasing

If you have ill-fitting or broken dentures, you may be experiencing a number of problems. Your dentures may slip and slide when you eat or talk. This can make it difficult for you to chew and can cause you to slur your words. You may also find that your dentures are uncomfortable to wear, causing irritation to your gums.

To prevent this from happening, many dentists recommend getting your dentures rebased to improve the fit. In this procedure, a new base is added to your existing dentures. This can help to improve their stability and comfort. In addition, it can make them look and feel more natural.

Rebasing is usually recommended because of:

  • Broken dentures
  • Weak or old acrylic denture base
  • Change from temporary to permanent dentures

Rebasing is often recommended when the teeth in your denture are still in good shape and have not worn out relative to the base.

Unlike relining, which only changes the material that contacts your gums, rebasing changes the entire denture base. This means that rebasing can provide a better fit than relining, as well as make your dentures look and feel like new.

If you are considering rebasing your dentures, here’s what you need to know:

The Process of Rebasing Dentures

Rebasing your dentures is usually a two-step process. First, your existing denture base will be removed. Next, a new denture base will be created and attached to your teeth. The whole procedure usually takes only a single day: one appointment in the morning and another in the afternoon.

During the first step of the process, your denturist will take an impression of your mouth. This impression will be used to create a model of your mouth, which will be used to create your new denture base.

Once your new denture base is ready, your denturist will try it in your mouth to ensure that it fits properly. Once you and your denturist are happy with the fit, the new denture base will be attached to your existing teeth.

Caring for Rebased Dentures

It is important to take care of your rebased dentures just as you would any other type of denture. Be sure to brush them daily and soak them in a denture cleaner overnight. You should also see your dentist regularly for checkups and cleanings.

With proper care, rebasing can provide you with many years of comfortable, functional dentures. Depending on the quality of the material of the dentures, you would likely need a rebase every five to seven years to ensure the best comfort and fit.


Rebasing your ill-fitting dentures is a great way to improve their fit and comfort. It can also be used to prevent or repair damages, such as cracks or breaks. Be sure to talk to your dentist or denturist about whether rebasing is right for you.
