Have you ever felt like your mouth is dry no matter how much water you drink? That’s what we call dry mouth, or xerostomia. It simply means your mouth isn’t making enough saliva — and while it may seem like a small thing, saliva actually plays a big role in keeping your mouth healthy.

Why Saliva Matters

Saliva isn’t just water — it helps wash away food bits, neutralize acids, and protect your teeth from decay. It also makes talking, chewing, and swallowing much easier.

What Causes Dry Mouth?

There are lots of possible reasons, such as:

• Taking certain medications (like for allergies, blood pressure, or anxiety)
• Not drinking enough water or getting dehydrated
• Mouth breathing, especially while sleeping
• Certain medical conditions like diabetes or Sjögren’s syndrome
• Smoking or drinking too much alcohol or caffeine

Common Signs to Watch For

• Sticky or dry feeling in your mouth or throat
• Cracked lips or a sore tongue
• Trouble speaking, chewing, or swallowing
• Bad breath that won’t go away
• More cavities or tooth sensitivity than usual
• Avoid alcohol, caffeine, and smoking, which can dry your mouth out more
• Use a humidifier while sleeping if you breathe through your mouth
• Keep up good brushing and flossing habits
• Ask your dentist about saliva substitutes or special mouth rinses made for dry mouth

When to See Your Dentist

If your mouth feels dry all the time or it’s affecting your comfort, don’t ignore it! Persistent dry mouth can increase your risk of tooth decay and gum problems. Your dentist can help find out what’s causing it and recommend the best treatment for you.
