Missing teeth can change the shape of your face.
Most people think losing a tooth only leaves a gap in their smile. But the changes don't stop there. Beneath the gums, the jawbone that once supported the tooth begins to shrink when it no longer receives the stimulation created by chewing.
Every time you bite and chew, forces travel through the tooth roots into the surrounding bone, helping maintain its strength and volume. When a tooth is lost, that natural stimulation disappears, and the body gradually starts resorbing the unused bone.
As bone loss progresses, the lower face can lose structural support. This may contribute to thinner-looking lips, a more sunken appearance around the mouth, deeper facial folds, changes in jawline contours, and an older-looking facial profile over time.
The image illustrates how continued tooth and bone loss can affect both the jawbone and the appearance of the face. While these changes occur gradually, they can become significant when missing teeth remain untreated for many years.
This is one reason dentists often recommend replacing missing teeth with appropriate treatment options. Preserving natural teeth whenever possible—and replacing them when necessary—helps maintain the bone that supports both oral function and facial structure.
Your teeth do more than help you chew and speak. They help preserve the foundation of your face.
