A complete denture is a removable dental appliance designed to replace all missing teeth in either the upper or lower jaw. It is custom-made to fit the shape of a person's mouth and is typically made from acrylic resin, which mimics the appearance of natural gums and teeth. Complete dentures help restore functionality, allowing individuals to eat and speak more comfortably. These dentures are held in place by the natural suction of the gums and can be adjusted for a better fit over time. Regular visits to a dentist are essential for maintenance and to ensure the dentures remain comfortable and effective.
