Partial dentures are used when one or more missing teeth are in either the upper or lower dental arch. Partial dentures often use metal clasps to anchor onto the remaining teeth for support, retention and stability. When they are properly designed and made, the partial dentures can be quite comfortable. However, the level of comfort is different for many people. For partial dentures, they are removable by the patient and so some level of movement during function is expected. But such movement is usually minimal and can depend on the state of the remaining teeth. Most patients often tolerate the minute movement.
In addition, because of the need to use metal clasps around the remaining teeth, some display of metal during smile may be unavoidable. Most of the time, the partial denture will always be designed to minimize the metal display. The location and amount of metal display depend on the location, the shape and the support of your remaining teeth. To avoid metal display altogether, one may consider using implant supported partial denture.
