Dentures are appliances that replace missing teeth which can be taken out and put back into your mouth. The materials used today have improved significantly and they can be made to look quite natural and comfortable although they will never feel exactly like your natural teeth. Most patients accommodate to these appliances quite well and they may be a good, viable alternative for you.
Dentures are usually classified as either full or partial. If the appliance replaces all of your teeth in an arch, it is called a full denture. If there are teeth remaining to help secure the appliance in place, then it is a partial denture. It is usually worthwhile to save any teeth on the bottom arch to avoid going to a full denture. The upper denture can usually be made to look and feel pretty comfortable because of the palate which helps to stabilize and retain the denture in place.
