Living with Dry Mouth After Radiation Therapy
Radiation therapy is an effective treatment for many cancers, but one of its lasting side effects is damage to the salivary glands. Many patients experience chronic dry mouth (xerostomia) after therapy because saliva production is reduced or eliminated.
Saliva plays an essential role in keeping the mouth healthy by:
Protecting against tooth decay
Neutralizing acids
Aiding in digestion
Preventing oral infections
When saliva is no longer present, patients are more vulnerable to cavities, gum disease, oral infections, and difficulty speaking or swallowing.
What Can Be Done?
At Morgan Family Dental, we understand the challenges patients face after radiation therapy. While saliva function may not fully return, there are effective ways to manage dry mouth and protect your oral health:
Stay hydrated: Sip water frequently throughout the day.
Sugar-free gum or lozenges: Stimulate saliva flow where possible.
Humidifier use: Adds moisture to the air, especially at night.
Avoid irritants: Tobacco, alcohol, and acidic or spicy foods can worsen symptoms.
Special Toothpaste Recommendations
Because dry mouth patients are at higher risk for cavities, using the right toothpaste is critical. Dr. Morgan recommends the following options:
Biotène Dry Mouth Toothpaste – Alcohol-free, fluoride-containing, gentle on sensitive tissue.
Colgate Hydris – Designed to relieve dry mouth while protecting against decay.
Clinpro 5000 (Prescription) – High-fluoride toothpaste to strengthen enamel and protect against cavities.
PreviDent 5000 (Prescription) – Another high-fluoride option specifically for patients with high cavity risk.
Your dental care routine should also include daily flossing and regular dental visits so that Dr. Morgan can monitor your oral health closely.
