1. Sharp teeth. Eating often bite the inner wall of the lips, may be the tip of the tooth is relatively sharp, up and down when biting easily damage the oral mucosa.
2. Teeth overlay coverage is too small. When a denture restoration is performed, the horizontal distance from the buccal cusp of the maxillary teeth to the buccal cusp of the mandibular teeth is too small, and cheek biting may also occur.
