Rest, over-the-counter medicines, drinking water, gargling with warm salt water, drinking warm and cold liquids, and using a cool mist vaporizer ease a sore soft palate, according to Drugs.com. In the absence of significant illness, the soreness normally does not last long and often goes away on its own.
These remedies ease the discomfort caused by viral pharyngitis and minor injury; other treatments are sometimes required to remove the cause of the pain. Antibiotics treat throat infections caused by bacteria. Minor burns from food or beverages or small abrasions to the soft palate heal fairly quickly on their own. Consult a medical professional if mouth pain prevents swallowing, if there is a fever above 101 degrees Fahrenheit or if breathing becomes noisy.
