When the condition of the teeth has deteriorated so far that they can no longer be repaired, removal is the only option. Dentures are a "replacement" option for missing teeth. There are two variations of dentures: partial dentures and full dentures. The difference between the two lies in how many natural teeth remain.
A complete denture is a removable prosthesis of white plastic teeth in a pink gum-colored plastic base; the denture rests on the remaining gum ridge once all of the teeth in the arch have been removed.
It is important to note that life with an upper and/or lower denture is a major lifestyle change when compared to natural teeth.
