What is the recommended interval for changing palatal obturators?

Explanation:
Dynamic changes in the tissues of the palate, especially in growing patients with cleft conditions, mean a palatal obturator can lose its fit quickly. As the mouth develops, dentition erupts, tissue tone shifts, and scar tissue contracts, so the prosthesis may no longer seal properly, compromising speech, swallowing, and comfort and potentially causing irritation or ulcers. Because of this, changing the palatal obturator every two to three months helps maintain a good seal, optimal function, and mucosal health. Longer intervals increase the risk of a poor fit and related problems.
