Complete dentures are removable dental appliances designed to replace all missing teeth in either the upper or lower jaw, or both. They are custom-made to fit the shape of a person's mouth and provide support for facial structures, improving appearance and function. These dentures are typically made from acrylic resin and may include metal components for added strength. Proper care and regular dental check-ups are essential to ensure a good fit and maintain oral health. Complete dentures can help restore the ability to chew and speak, enhancing overall quality of life for individuals with tooth loss.
