Dry Mouth Isn’t Just a Nuisance—It’s a Dental Danger

Let’s talk about something that sounds minor but affects millions—and not in a good way: dry mouth. Whether it feels like sandpaper in the morning or a constant cottonmouth throughout the day, this is more than a nuisance. As your dentist in Los Angeles, CA, I see the damage it causes—cavities, cracked teeth, bad breath—and often, it’s preventable by practicing preventive dental care. So, let’s dive into what’s really going on and how we can bring some balance back to your mouth (and your comfort). 

Why Your Mouth Needs Moisture 

Saliva does more than you think. It’s your body’s natural defense system in the mouth. It washes away food particles, neutralizes acids, helps you taste and digest food, and even delivers minerals that help repair tooth enamel. So when saliva production drops, everything gets out of balance—and fast. You may notice your mouth burning, your tongue sticking to your teeth, or that water just doesn’t cut it anymore. 

What Causes Dry Mouth? 

There’s no single cause, but here are the most common culprits I see in my chair: 

• Medications – especially those for high blood pressure, depression, anxiety, allergies, or pain. Even over-the-counter antihistamines and decongestants can dry you out. 

• Autoimmune conditions like Sjögren’s syndrome, rheumatoid arthritis, or lupus. 

• Diabetes and other metabolic disorders. 

• Cancer treatment, especially radiation to the head and neck. 

• Mouth breathing which is often related to snoring or nasal blockages. 

• Aging - Saliva flow naturally decreases with age. 

• Dehydration - The most obvious (and easiest to fix!). Contact us to learn more. 

The Damage You Don’t See—Until It’s Too Late 

Dry mouth may seem harmless at first—but it’s sneaky. Without saliva, harmful bacteria thrive, and acids aren’t buffered the way they should be. This leads to: 

• Rapid tooth decay, especially along the gum line or around existing dental work 

• Gum inflammation and bleeding 

• Difficulty wearing dentures 

• Persistent bad breath 

• Cracks at the corners of the mouth 

• Changes in taste or trouble swallowing 

As a dentist in West Los Angeles, CA, I’ve seen patients with nearly perfect dental records suddenly develop a mouth full of cavities—just because of medication-induced dry mouth. It’s real, and it’s worth addressing. 

What You Can Do About It 

Here’s what I tell my patients: 

• Stay hydrated - but go beyond just water. Add electrolytes or coconut water occasionally to replenish minerals. 

• Chew xylitol gum to stimulate natural saliva (and reduce cavity risk). 

• Use over-the-counter dry mouth rinses - especially at night. 

• Avoid alcohol-based mouthwashes, caffeine, and tobacco. 

• Sleep with a humidifier - especially if you breathe through your mouth. 

• Ask your physician about adjusting medications, if possible. 

• Come see me regularly - I can track early signs and help protect your enamel before things go south. 

A Friendly Note from Me (and Your Salivary Glands) 

Dry mouth is manageable—but only if you catch it early and take it seriously. Whether you’re struggling with comfort, swallowing, or just feel like your smile is dull and sticky, let’s talk. You’re not alone, and you’re not stuck. Along with both my hygienists, Angela and Gita, we have lots of tips that can make a real difference.
