The most common replace missing teeth are dentures, bridges, and dental implants. Dentures are removable prosthetic teeth that are custom-made to fit one's mouth. They can be either partial, replacing a few missing teeth, or full, replacing all of the teeth in either the upper or lower jaw. Dentures are typically the most affordable option for teeth replacement, costing anywhere from $300 to $5,000 per arch, depending on the type and materials used.
