What is the primary purpose of maxillary anterior denture teeth if they are not visible?

The primary purpose of maxillary anterior denture teeth, even when not visible, centers around providing essential support for speech and lip movement. The anterior teeth play a critical role in maintaining the contour of the lips and the overall facial profile. They contribute to the proper alignment of the oral cavity, ensuring that speech sounds can be articulated accurately.

Without the anterior teeth, even if they're not visible, there can be adverse effects on phonetics and the natural resting position of the lips. Maintaining this support is crucial for a patient's comfort and confidence in social interactions.

Support for the dental arch is typically the role of the posterior teeth and the denture base itself. Sensory feedback during chewing is primarily associated with posterior teeth where most masticatory forces occur. While facial aesthetic enhancement is also important, the anterior teeth's primary function goes beyond mere appearance to fundamentally influence everyday functions like speaking and maintaining proper oral structure.
