If you have missing teeth, a removable partial denture is one way to replace them. Removable partial dentures usually have replacement teeth fixed to a plastic base that matches the color of your gum tissue. The plastic base may cover a metal framework. Partial dentures have some form of clasp that attaches to your natural teeth. There is an adjustment period in getting used to wearing a partial denture. This may include salivating, and affecting your speech temporarily.
