What is a denture rebase?

A denture rebase means the base of a denture is replaced with new material, but the teeth attached to it may stay the same.

The base is the part that rests on your gums. Over time, that part can wear down, crack, or stop fitting well. A provider may use the word rebase when the denture teeth are still usable, but the base needs more than a small adjustment.

This is different from a reline. A reline adds or adjusts material on the inside of the denture to improve contact with your gums. A rebase is a bigger remake of the denture base itself.

You may also hear other denture words. A full denture replaces all teeth in the upper or lower arch. A partial denture replaces some missing teeth and fits around natural teeth. An immediate denture is placed soon after teeth are removed. A soft liner is a softer layer placed inside some dentures for comfort in certain cases. An overdenture, also called an implant-supported denture, is a denture that connects to dental implants. A denturist is a licensed professional in some states who makes and fits dentures, but rules vary by state.

If a provider mentions a rebase, they are talking about the denture itself, not just your gums. It can be one option a licensed denture or dental provider considers when a denture base has changed, but the teeth may still be worth keeping.

A rebase is not the same as making a brand-new denture from the start. But it is also not as simple as a quick chairside adjustment. What makes sense depends on the denture's condition, the fit, the bite, the age of the denture, and what the provider sees during an exam.

Cost can vary. In the US, denture work like this may range from a few hundred dollars to more, depending on the type of denture, materials, provider, and area. These are not quotes.

If you are comparing terms, it may help to ask a provider:
- What is the difference between a reline and a rebase for my denture?
- Are the denture teeth still in good enough shape to keep?
- How long might the denture be out of my mouth, if lab work is needed?
- What are the total costs, and what do they include?

A licensed provider can explain your options in a way that fits your situation.
