If your mouth feels sticky, pasty, or parched most of the day, you’re not alone—and it’s not something to ignore. Persistent dry mouth, also called xerostomia, happens when your salivary glands don’t produce enough saliva.
At Arrow Dental Arts, our Rancho Cucamonga Dentists recommend addressing dry mouth early because saliva is essential for protecting your teeth, gums, and overall oral comfort.Below, you’ll learn what causes dry mouth, why it matters, and the most effective ways to find relief.
Why Saliva Matters
Saliva isn’t just water. It’s a protective fluid that:
- Neutralizes acids and balances your mouth’s pH
- Washes away food particles and bacteria
- Delivers minerals (like calcium and phosphate) to strengthen enamel
- Aids chewing, swallowing, and speaking
- Supports taste and comfort
When saliva is low, your risk of cavities, gum disease, bad breath, and oral infections rises significantly.
Common Signs You’re Dealing with Xerostomia
- A sticky or cottony feeling in the mouth
- Frequent thirst or waking up at night for water
- Cracked lips or corners of the mouth
- Sore throat, hoarseness, or trouble swallowing dry foods
- Changes in taste or burning mouth sensations
- Bad breath
- More plaque buildup or new cavities, especially along the gumline
- Difficulty wearing dentures
If these sound familiar, our Rancho Cucamonga Dentists recommend a professional evaluation at Arrow Dental Arts to identify the cause and protect your smile.
What Causes Dry Mouth?
Dry mouth can be temporary or chronic. Common causes include:
- Medications: Antihistamines, decongestants, antidepressants, anti-anxiety meds, blood pressure medications, diuretics, muscle relaxants, and many others can reduce saliva.
- Dehydration and lifestyle: Not drinking enough water, high caffeine intake, alcohol, vaping, and tobacco use.
- Mouth breathing and snoring: Nasal congestion, deviated septum, or sleep apnea can dry the mouth—especially at night.
- Health conditions: Diabetes, Sjögren’s syndrome, thyroid disorders, anxiety, depression, and autoimmune conditions.
- Cancer treatments: Head and neck radiation and certain chemotherapy drugs can affect salivary glands.
- Aging and hormonal changes: Natural changes in saliva quantity and quality can occur over time.
Pinpointing the cause helps guide the right treatment plan. Our Rancho Cucamonga Dentists recommend bringing a list of your medications and supplements to your appointment.
Is Dry Mouth Serious?
Yes—especially if it’s persistent. Without adequate saliva, you’re more likely to experience:
- Rapid cavity formation, particularly on root surfaces
- Gum inflammation and periodontal disease
- Oral thrush (yeast infections)
- Tooth sensitivity and enamel erosion
- Bad breath and altered taste
- Discomfort with dentures or oral appliances
The good news: with the right plan, you can reduce symptoms and protect your oral health.
At-Home Relief Tips Our Rancho Cucamonga Dentists Recommend
- Hydrate strategically: Sip water frequently throughout the day. Keep a bedside water bottle if nights are a problem.
- Stimulate saliva: Chew sugar-free gum or suck on sugar-free lozenges—xylitol options can help reduce cavity risk.
- Breathe through your nose: Treat nasal congestion and consider a humidifier at night to add moisture to the air.
- Limit drying agents: Cut back on caffeine and alcohol, and avoid smoking or vaping.
- Choose the right oral care products:
- Use fluoride toothpaste twice daily; consider a high-fluoride toothpaste if you’re cavity-prone (ask us if it’s right for you).
- Rinse with alcohol-free mouthwash formulated for dry mouth.
- Consider remineralizing products (e.g., CPP-ACP or nano-hydroxyapatite) to help strengthen enamel.
- Eat smart: Opt for moist foods, sauces, and broths. Limit acidic or spicy foods if they sting.
- Avoid sugary mints or acidic candies: They can worsen decay and irritation.
If you’re still uncomfortable after two weeks of consistent home care, our Rancho Cucamonga Dentists recommend a professional visit to Arrow Dental Arts.

When to See a Dentist
Book an appointment if you experience:
- Dry mouth lasting longer than two weeks
- New cavities or tooth sensitivity appearing suddenly
- Sore, red, or white patches in the mouth

Early care can prevent complications—and save you from costly treatments later.
Frequently Asked Questions
- Is drinking more water enough?
Water helps, but it may not fix the underlying cause. You’ll get better results by combining hydration with saliva stimulation, smart product choices, and professional care. - Which medications commonly cause dry mouth?
Antihistamines, decongestants, certain antidepressants and anti-anxiety meds, blood pressure medications, diuretics, and muscle relaxants are frequent culprits. Bring your list to your visit so we can help strategize. - Can dry mouth be reversed?
Sometimes. If the cause is dehydration or a modifiable habit, symptoms can improve. Medication- or therapy-related dryness can often be managed effectively with a combined home and professional plan. - Why is my mouth driest at night?
Mouth breathing, snoring, or sleep apnea often worsen night-time dryness. A humidifier, nasal support, and evaluation for sleep-disordered breathing can help. - Are alcohol mouthwashes bad for dry mouth?
Alcohol can be drying. Choose alcohol-free rinses designed for dry mouth.
