Dentures are removable dental appliances designed to replace missing teeth. They can be made from various materials, including acrylic resin and metal, and are custom-fitted to the individual's mouth for comfort and functionality. Dentures help restore the ability to chew food and improve speech, while also enhancing the appearance of a person's smile. There are two main types of dentures: complete dentures, which replace all teeth in the upper or lower jaw, and partial dentures, which fill in gaps when some natural teeth remain. Regular dental check-ups are important to ensure proper fit and maintenance of dentures for optimal oral health.
