Upper vs Lower Dentures: What Is Different?

About this guide

This guide is designed to help patients understand common questions about dentures in plain language. It is intended as general patient education and should be read alongside advice from the dental professional responsible for your care.

Overview

Upper and lower dentures replace teeth in different arches and interact differently with the anatomy of the mouth. Upper dentures generally have a broader area over which support and retention can be developed.

What to know

Lower dentures have a smaller supporting area and are influenced by the tongue, cheeks and movement of the lower jaw. Some patients find lower dentures more difficult to stabilise.

What your dental professional may consider

Fit, anatomy, saliva, muscle control, ridge shape and previous denture experience can all affect performance. Persistent instability should be assessed professionally.

Practical points

A dentist may discuss options such as adjustment, relining, replacement or, where appropriate, implant-assisted retention.

When to seek professional advice

Contact a qualified dental professional if you have persistent pain, repeated sore areas, a denture that is consistently loose or unstable, a broken appliance, unexplained changes in your mouth, or concerns about eating or speaking. Do not attempt irreversible repairs or adjustments at home.
