There are three main types of dentures: partial, conventional and immediate. A partial denture is used when there are still some good teeth left. You may only need to replace one or two teeth and so a partial denture or plate is sufficient. If you have had all your teeth out, you can choose to have an immediate denture so that you don't have to go without teeth.

The measurements and fittings for an immediate are usually done before the teeth are extracted. After they have been out for a while and your gums have healed there is usually some shrinkage, so the immediate plate needs to be adjusted or replaced with a conventional plate.

The patient's mouth is fitted for a conventional denture several months after having all teeth out. This ensures that all changes to shape and size are over and the plate will fit well. Most people don't like being without any teeth for months so they opt for immediate and then conventional dentures.

Dentures can be for the top or the bottom of the mouth. Top dentures usually fit better than bottom ones. They have a plate that covers the roof of the mouth. Bottom dentures are shaped more like a horseshoe to allow room for the tongue.
