A denture is a removable replacement for missing teeth and surrounding tissues. There are two types of dentures available, including partial and complete dentures. Partial dentures are used when some natural teeth remain, while complete dentures are used to completely replace all teeth. Dentures are made to resemble your natural teeth so there should be no noticeable change to your appearance. In fact, dentures not only improve your smile, but can improve facial features by supporting your lips and cheeks.
