What happens when you don’t have teeth?
Before you start to wonder how dentures will affect your appearance, you might first want to think: How will not having teeth affect your appearance? Teeth do more for your mouth than just chew and look pearly. They also provide support to the soft tissues in your cheeks to stay in place. Teeth won’t completely stop your face from sagging, but they do prevent it. If your teeth are gone, then your jawbone will also begin to lose density and structure. Overall, your face can age quicker than it would if all of the parts it needs were still there.

How do you want your new teeth to look?
After you understand how dentures will affect your whole face, you can think about your smile. How do you want it to look? Your denture teeth can be modeled to look perfectly straight and white, if you want. More often people will request that they look as much like their former natural teeth as possible. That can even include some “imperfections” – if you had a gap between your front teeth that you feel was characteristic to your smile, then that can be recreated in your denture.
