Yes, missing teeth can have a noticeable impact on the shape of your face. Teeth provide essential support for your jawbone, cheeks, and lips. When teeth are lost, the bone in the jaw begins to shrink over time due to lack of stimulation, leading to a sunken or hollow appearance in the face. This can make your cheeks appear droopy, lips thinner, and cause premature wrinkles around the mouth. Additionally, the alignment of remaining teeth can shift, further affecting facial symmetry. Replacing missing teeth through implants, bridges, or dentures can help maintain the natural shape and structure of your face, preserving a youthful appearance.
