There's nothing better than your own teeth, however, when needed, dentures are removable replacements for missing teeth. Complete dentures are finely crafted and custom-fitted, typically made out of acrylic resins, which at times incorporates porcelain or metal for additional structural support. If you properly maintain your dentures they will appear natural and provide an almost perfect smile. Additionally, dentures help strengthen muscles controlling your expressions that require the support of your teeth, rid you of pronunciation problems caused by missing teeth, and aid with chewing. A denture may prevent a sagging face by providing support for lips and cheeks.
