Winter Dry Mouth: Causes and Solutions for New Englanders

Lower humidity levels, combined with dehydrating indoor heating systems, reduce natural moisture. Additionally, increased mouth breathing due to stuffy noses from colds or flu can dry out oral tissues rapidly, reducing saliva flow that protects teeth.

The Problem with Dry Mouth (Xerostomia)

Saliva isn't just moisture; it's your mouth's primary defense system. It washes away food particles, neutralizes acids produced by bacteria, and contains minerals that repair enamel. When saliva flow decreases, your risk for cavities, gum disease, and bad breath skyrockets.

Combatting the Winter Dryness

Living in MetroWest means battling dry air for months. Here are simple strategies to stay comfortable and protected:

1. Humidify Your Home

Running a humidifier in your bedroom at night can significantly reduce morning dry mouth. Aim for 30-50% humidity.

2. Stay Hydrated

Drink water throughout the day. Sip, don't gulp. Keeping the mouth moist consistently is more effective than drinking a large amount at once.

3. Use Saliva Substitutes

Over-the-counter products like Biotene rinse or spray can provide relief. Look for "alcohol-free" mouthwashes, as alcohol dries out tissues further.

4. Chew Sugar-Free Gum with Xylitol

Chewing stimulates saliva production. Xylitol, a natural sweetener, also helps inhibit cavity-causing bacteria.

When to See a Dentist

If dry mouth persists despite these measures, or if you take medications (like antihistamines or decongestants) that list dry mouth as a side effect, book a visit. We can recommend prescription-strength fluoride or other therapies to protect your enamel.
