Detailed explanation-1: -Your salivary glands lubricate your mouth, help you swallow, aid in digestion and help protect your teeth against harmful bacteria. You have three major types of salivary glands, including your sublingual, submandibular and parotid.

Detailed explanation-2: -A few big sips of water may help you wash down the food stuck in your esophagus. Normally, your saliva provides enough lubrication to help food slide easily down the esophagus. If your food wasn’t chewed properly, it may be too dry. Repeated sips of water may moisten the stuck food, making it go down more easily.

Detailed explanation-3: -If it is an acute blockage, such as food or a foreign object, emergency treatment using an endoscope or surgery will be required to remove the blockage. Usually a scan called a contrast scan show a narrowed area of the foodpipe.

Detailed explanation-4: -Dysphasia is usually a sign that there is a problem with your esophagus, the muscular tube that moves food and liquids from the back of your mouth to your stomach. If dysphagia is severe, you may not be able to take in enough fluids and calories to stay healthy. In severe cases, even saliva is difficult to swallow.
