Dry mouth (also called xerostomia) means your child's mouth does not make enough saliva. Saliva is the liquid that keeps the mouth moist, helps with swallowing, and protects teeth from cavities.
Key facts
Dry mouth is fairly common in children, especially when they take certain medicines (like for allergies or ADHD) or when they are dehydrated from fever or not drinking enough.
It can affect children of any age, but it is more common in those who breathe through their mouth (often due to allergies or a stuffy nose), take certain medications, or have health conditions that affect saliva production.
The doctor will ask about your child's symptoms, medicines, and drinking habits. They will look inside your child's mouth to check for dryness, cavities, or other problems.
The doctor may ask your child to open wide, stick out their tongue, or sip water. They may review any medicines your child takes. The visit is usually quick and comfortable.
Treatment focuses on the cause. For example, if a medicine is causing it, the doctor may adjust the dose or switch medicines. If dehydration is the cause, increasing fluids will help.
Dry mouth is a manageable condition. The key is to keep your child's mouth moist and protect their teeth. Offer frequent small drinks, avoid sticky or sugary foods, and keep up with regular dental check-ups.
Soft, moist foods are easier to eat. Offer soups, yogurts, smoothies, and applesauce. Avoid dry, hard, or salty foods. Staying hydrated is also important during exercise. Make sure water is always available.
Mild dry mouth is not harmful, but it can be annoying or make your child feel self-conscious about their breath. Reassure your child that it is common and usually temporary. Good oral hygiene and sugar-free gum can help with bad breath.
Many cases can be prevented by making sure your child drinks enough water, especially when they are sick or active. Treating mouth breathing from allergies or a stuffy nose can also help. If your child takes medicines that cause dry mouth, talk to the doctor about alternatives.
With proper care, dry mouth in children is usually temporary and easy to manage. Treating the cause and practicing good oral hygiene can prevent most problems. Most children return to normal quickly.

If symptoms are severe, worsening, or urgent, call your local emergency number or seek emergency care.
If home care is not enough, a doctor may recommend saliva substitutes (like special mouthwashes or sprays) or medicines that help the body make more saliva. These are prescribed based on your child's specific needs. Always talk to your doctor before trying any new product.
Surgery is rarely needed for dry mouth. It may be considered if a blockage in the saliva gland is causing the problem.
