When a patient experiences pain on swallowing while wearing dentures, what could be the likely cause?

The experience of pain during swallowing while wearing dentures can often be attributed to an overextension of the lingual flange. This condition occurs when the denture extends too far back towards the throat area, potentially irritating sensitive tissues. The excessive contact can induce discomfort, particularly during activities such as swallowing, where the tongue and other oral structures move dynamically.

Proper denture design requires careful consideration of the anatomy of the oral cavity, especially in relation to the positioning of the denture flanges. An overextended lingual flange may not only cause pain but can also lead to difficulties in speaking and a feeling of bulkiness, further exacerbating discomfort during normal functions like swallowing.

While improper fit of the denture, excessive vertical dimension of occlusion, and insufficient support are plausible factors contributing to various forms of discomfort and issues with dentures, they do not specifically pinpoint the direct cause of pain on swallowing as accurately as the overextension of the lingual flange does. Proper assessment of the denture's fit and adjustments can often remedy the situation, ensuring a more comfortable experience for the patient.
