Dry mouth, also known as xerostomia, is the reduced flow of saliva. Sufficient saliva is needed in the mouth to wash away food debris and reduce plaque by neutralizing the acids that plaque produces.

Gingivitis, gum disease and severe tooth decay often occur if dry mouth is left untreated. Other common problems linked to dry mouth are:

• Difficulty speaking
• Hoarseness
• Persistent sore throat
• Problems with speaking
• Problems with swallowing
• Burning sensation in the mouth
• Dry nasal passages

If you suffer from dry mouth, be sure to discuss treatment methods, such as saliva substitutes, with your dentist. Sugar-free gum and candy also can increase saliva flow.
