You’ve probably heard that drinking water is important for your overall health—but did you know it’s just as essential for your smile?
At Complete Dental Care, one of the most overlooked topics I talk about with patients is saliva. It might not be glamorous, but saliva plays a vital role in protecting your teeth and gums. In our dry Phoenix climate, staying hydrated is more important than ever.
Let’s take a closer look at how saliva keeps your mouth healthy—and what happens when you don’t have enough of it.
Why Saliva Is More Important Than You Think
Saliva is more than just water. It contains a powerful mix of enzymes, proteins, and minerals that keep your mouth in balance. Here’s what it does every day without you even realizing it:
- Neutralizes acids produced by bacteria and acidic foods
- Washes away food particles after meals and snacks
- Delivers calcium and phosphate to strengthen enamel
- Helps prevent cavities and gum disease by controlling harmful bacteria
Basically, saliva is your body’s natural mouthwash—and you’re producing it all day long (or at least you should be).
What Happens When You Don’t Have Enough Saliva?
Dry mouth—also known as xerostomia—happens when your body doesn’t produce enough saliva. It’s surprisingly common, especially in places like Phoenix where heat and dehydration are everyday concerns.
Common Causes of Dry Mouth:
- Dehydration (often from not drinking enough water or exposure to dry air)
- Medications (especially for blood pressure, allergies, anxiety, or pain)
- Aging
- Health conditions like diabetes or autoimmune disorders
Symptoms to Watch For:
- A sticky, dry feeling in your mouth or throat
- Cracked lips or a dry tongue
- Bad breath that won’t go away
- Difficulty chewing or swallowing
- Increased risk of cavities or gum irritation

How Dry Mouth Affects Your Teeth
When saliva production slows down, your teeth lose their natural defense system. Here’s what can happen:
- Acids stay around longer and erode your enamel
- Bacteria multiply and lead to cavities
- Gums become dry and more vulnerable to infection
- Teeth become more sensitive and more prone to decay
If you’re concerned that dry mouth may already be affecting your teeth, take a look at our guide on How Do I Know if I Have a Cavity? for early warning signs.
Staying Hydrated: Your First Line of Defense
Drinking water regularly throughout the day is one of the simplest and most effective things you can do for your oral health. Here are a few tips:
- Sip water throughout the day, not just when you feel thirsty
- Drink extra if you consume caffeine, alcohol, or salty foods
- Use sugar-free gum or mints to stimulate saliva production
- Avoid sugary or acidic beverages, which dry the mouth and erode enamel
