A missing tooth can often be replaced by suspending a replacement tooth from adjoining crowns on neighboring teeth. The bridge is cemented or bonded permanently into your mouth.
An implant is a replacement for the root of a missing tooth. It is placed and then allowed to heal/ integrate to the surrounding bone. After mending, the implant can be used to support a crown or to help retain a removable appliance.
Missing teeth can also be replaced using partial dentures held into position by the remaining teeth or complete dentures to replace the entire upper or lower arch.
