Dentures are removable appliances that replace missing teeth and restore your smile. If you’ve lost some or all of your natural teeth, whether from gum disease, tooth decay, or injury, replacing them benefits your appearance and health. Dentures make it easier to eat and speak than you could without teeth. Dentures can also fill out the appearance of your face and profile. They can be made to closely resemble your natural teeth and improve the look of your smile.
