Crowns are also used to attach bridges, cover implants, and prevent a cracked tooth from becoming worse, or an existing filling is in jeopardy of becoming loose or dislocated. Crowns also serve an aesthetic use, and are applied when a discolored or stained tooth needs to be restored to its natural appearance.

Dentures on the other hand are designed to replace missing teeth, and are worn by millions of Americans. Technological advancements have resulted in dentures that are lightweight and mimic the look and feel of natural teeth. Most dentures are made from a combination of metals and synthetic material such as acrylic resin.

Dentures are generally classified as partial or full. Partial dentures are designed to replace a small section of teeth, and help prevent existing healthy natural teeth from shifting position, where full dentures generally replace an entire set of teeth such as upper and lower dentures.
