Partial Dentures: Partial dentures can either be made with a plastic base or a metal framework that supports the number of teeth that need to be replaced. It is held in the mouth by using clasps and rests that are carefully adapted around the natural teeth. The partial denture that uses a metal framework is the traditional design, due to the rigidity and strength of the metal. Plastic partial dentures have normally been used as emergency or temporary replacements of missing teeth, allowing the gums and bone to heal before a definitive restorative solution is obtained. Recently, however, various materials such as Valplast have been developed to provide durable, flexible alternatives in certain situations.
You may need new dentures if they are discolored, severely deteriorated or uncomfortable. Yellow or brown stains are the most common types of discoloration. Meanwhile, deteriorating dentures won't tear or grind food properly when you bite into something or chew. Dentures that don't fit properly can cause pain. If you're unsure how dentures should fit or feel, talk to your dentist.
