“A denture is a removable replacement for missing teeth and surrounding tissues. Two types of dentures are available — complete and partial dentures. Complete dentures are used when all the teeth are missing, while partial dentures are used when some natural teeth remain.” -WebMD
Complete dentures are total tooth replacement dentures for your mouth. They are ready to be placed in the mouth about eight to 12 weeks after the teeth have been removed. Immediate dentures are often a preferable option because the new teeth are made in advance and can be worn as soon as the removal is complete. These offer the advantage of a patient not having to go without teeth for 12 weeks, but they require more adjustments as the mouth heals.
Partial dentures, or a bridge, usually consist of replacement teeth attached to a pink or gum-colored plastic base. The base is connected by metal framework that holds the denture in place inside the mouth. These can be fixed, or permanent and will act and look completely natural. Bridges are generally used when one or more natural teeth remain in the upper or lower jaw. Additionally they will prevent your other teeth from moving and needing future cosmetic adjustments.
