What causes a dry or涩 feeling in the upper palate?

A dry and gritty sensation in the palate is usually caused by reduced saliva production during sleep. It is recommended to visit a professional dental department for an examination of the oral mucosa of the maxilla, salivary gland function, and salivary duct conditions. Burning mouth syndrome or salivary gland disorders may be present; therefore, it is important to first obtain an accurate diagnosis before initiating effective treatment. When going to the hospital for evaluation, eat more vegetables and fruits, drink plenty of warm water or honey water, maintain good oral hygiene, develop the habit of brushing teeth in the morning and evening, and adopt a healthy lifestyle.
