Dry mouth, also known as xerostomia, is a condition in which the salivary glands in the mouth do not produce enough saliva to keep the mouth moist. Saliva is essential for maintaining healthy teeth and gums, as well as for digesting food. A dry mouth can be caused by several factors, including certain medications, radiation therapy, dehydration, and aging. Symptoms of dry mouth include a feeling of dryness in the mouth, difficulty swallowing or speaking, and a sticky or dry sensation in the mouth. Dry mouth can be treated with over-the-counter products, such as mouthwashes and oral moisturizers, or with medications prescribed by a doctor.

What are the complications of dry mouth?

Dry mouth can affect more than just comfort. When the mouth does not produce enough saliva for a long time, it can increase the risk of several oral health problems, including:

• Tooth decay: Reduced saliva can allow harmful acids and bacteria to remain in the mouth, increasing the risk of cavities.

• Oral infections: Dry mouth can increase the risk of infections such as oral thrush.
• Difficulty eating and swallowing: Insufficient saliva can make chewing and swallowing food uncomfortable.
• Difficulty speaking: A dry mouth can make speaking for longer periods uncomfortable.
• Bad breath: Reduced saliva flow can allow bacteria and food particles to accumulate, contributing to bad breath.
• Changes in taste: Some people with persistent dry mouth may notice changes in their sense of taste.
