(HealthDay News) -- Certain medications and medical conditions can lead to dry mouth, a result of too little saliva flow.

Here's a list of problems that are associated with the condition, courtesy of the American Dental Association:

• A constant sore throat
• A burning sensation.
• Problems speaking.
• Difficulty swallowing.
• Dry nasal passages.

Because saliva washes away food and neutralizes the acids produced by plaque, dry mouth can damage teeth.

Dentists can usually recommend ways to restore moisture, such as sugar-free gum and oral rinses.
