Dentures are removable dental appliances designed to replace missing teeth and restore the functionality and appearance of a person's smile. They are custom-made to fit snugly over the gums, providing a natural-looking solution for those who have lost teeth due to decay, injury, or other health issues. Dentures come in two main types: full and partial. Full dentures are used when all the natural teeth are missing, while partial dentures are ideal for patients who still have some of their natural teeth remaining.
