The Role of Saliva in a Child’s Oral Health

Brushing, flossing, and regular dental checkups are the most important steps in maintaining your child’s oral health. While these are critical, saliva is another unsung hero in your child’s mouth! This natural fluid plays a vital role in protecting teeth and gums.

What Is Saliva?

Saliva is a clear, watery fluid produced by glands in your mouth. Your child’s mouth creates about 2 to 4 pints of saliva daily! It’s mostly made of water but also contains enzymes, proteins, minerals, and antibacterial compounds.

How Does Saliva Protect Your Child’s Teeth?

Saliva is essential to keeping your child’s mouth clean and healthy. Here’s how:

• Washes Away Food and Debris

Saliva helps remove food particles and sugars from the mouth, lowering the risk of cavities by preventing bacteria from feeding on leftover food.

• Neutralizes Acids

When your child eats sugary or acidic foods, harmful acids are produced that can weaken tooth enamel. Saliva helps neutralize these acids, protecting the teeth.

• Fights Bacteria

Saliva contains enzymes and proteins that attack harmful bacteria, keeping the mouth’s bacteria balance in check.

• Remineralizes Teeth

Saliva contains minerals like calcium and phosphate, which help repair and strengthen tooth enamel.

• Aids in Digestion

The enzymes in saliva break down food even before your child swallows, making it easier to digest.

What Happens When There’s Not Enough Saliva?

Sometimes, your child’s mouth may not produce enough saliva. This condition, known as dry mouth (xerostomia), can lead to several oral health issues, such as:

• Increased Risk of Cavities
• Bad Breath
• Difficulty Eating
• Mouth Sores

What Causes Dry Mouth?

Several factors can lead to a decrease in saliva production, including:

• Dehydration – Not drinking enough water is a common cause.
• Medications – Certain medications, especially antihistamines, decongestants, and treatments for ADHD, can reduce saliva production.
• Illness – Some illnesses, such as colds or allergies, may temporarily cause dry mouth.
• Mouth Breathing – Children who frequently breathe through their mouths, especially at night, may experience dry mouth.

How Can You Help Maintain Healthy Saliva Flow?

Luckily, there are easy ways to help your child maintain healthy saliva levels:

• Make sure your child drinks plenty of water throughout the day, especially after eating.
• Chewing sugar-free gum stimulates saliva production.
• Limit foods that can contribute to tooth decay or dry mouth, like candy, soda, and citrus.
• Bring your child to our pediatric dental office in Spring for routine exams and cleanings. 

The Importance of Regular Checkups
