Cosmetic dentures are designed to improve the esthetic appeal of a person's face. Cosmetic dentures can be used to close gaps between teeth, replace missing teeth or improve upon previously-done denture work. Cosmetic dentures are made mainly from acrylic or cobalt chromium. Chromium cosmetic dentures are used when there are some teeth remaining. A complete denture set is usually made from gum-colored acrylic as it is lighter. Cosmetic dentures are a non-invasive procedure and anyone in good medical health can have a denture set made. The only requirement is that the patient have healthy gums so that there are enough gum ridges to ensure denture retention. In the absence of healthy gums, dental implant cosmetic dentures are an alternative.
