Yes, dentures can change your face shape over time, particularly if they are old, worn down, or no longer fit your shifting jaw structure properly. When natural teeth are lost, the jawbone naturally experiences ongoing shrinkage because it no longer receives stimulation from tooth roots. While a fresh, precisely fitted appliance beautifully restores your youthful facial proportions by supporting your lips and cheeks, an outdated plate will gradually lose its vertical height, often leading to a sunken mouth appearance, thinner lips, and a more pronounced chin.

Understanding the Relationship Between Your Jaw and Facial Contours
How Bone Resorption Alters Your Profile
The foundational structure of your lower face relies heavily on the alveolar bone, which is the part of the jaw that holds your teeth. Once those teeth are gone, the body naturally reabsorbs this bone tissue over time. As the ridge shrinks, the distance between your nose and chin decreases when your mouth is closed. This biological shift is what causes the skin around the lower face to wrinkle or sag, creating an prematurely aged appearance if the physical volume is not properly replaced.
The Impact of Vertical Dimension Loss
Every prosthetic is manufactured to a specific height, known clinically as the vertical dimension of occlusion. Over years of daily chewing, the acrylic teeth and base materials slowly wear down, reducing this crucial height. This micro-wear forces your jaw to close further than it should, pushing your chin forward and causing the corners of your mouth to turn downward, which can sometimes lead to persistent skin irritation in the creases.
How Quality Fabrications Provide Structural Support
A well-engineered upper or lower plate acts as an internal scaffolding for your facial muscles. By carefully calculating the thickness of the acrylic flange and the positioning of the teeth, a dental prosthetist can physically plump out the area around your lips and cheeks. This targeted support smooths out fine lines and prevents the collapsed look, ensuring your natural facial expressions and features remain fully balanced.
Indicators That Your Appliance Is Changing Your Face Shape
- Increased Facial Sagging: You notice your cheeks looking more hollowed out or your lips turning inward, even when your teeth are fully in place.
- Changes in Bite Alignment: Your lower jaw feels like it has to shift forward or upward excessively just to make the upper and lower teeth meet while eating.
- Loose Fit and Moving Plates: The underlying bone has shrunk enough that a large gap has formed beneath the acrylic base, causing the appliance to slip or rock during conversation.
Maintaining your natural appearance requires a proactive approach to the changing landscape of your mouth. Because jawbone shrinkage is a continuous biological process, regular clinical reviews are essential to ensure your appliance continues to give your facial features the structural support they need to look vibrant and healthy.
