Cancer and its treatments, particularly radiation therapy to the head and neck, can cause dry mouth, also known as xerostomia, by damaging salivary glands and reducing saliva production.
How Cancer Treatment Can Cause Dry Mouth:
- Radiation Therapy
Radiation therapy to the head and neck area can damage the salivary glands, which produce saliva, leading to reduced saliva flow and a dry mouth.
- Chemotherapy
Some chemotherapy drugs can also affect saliva production and cause dry mouth.
- Surgery
Surgical removal of salivary glands will cause an immediate and permanent dry mouth. - Effects of Dry Mouth
Dry mouth can make it difficult to eat, swallow and talk. It can also increase the risk of dental cavities, gum disease, and oral infections. Saliva helps break down food, neutralize acids, and prevent bacterial overgrowth, so a lack of saliva can lead to these problems.
Managing Dry Mouth:
- Stay Hydrated: Drink plenty of water throughout the day.
- Sip Water Regularly: Sip water frequently to keep your mouth moist.
- Use Artificial Saliva: Consider using artificial saliva products to help keep your mouth moist.
- Eat Soft Foods: Choose soft foods that are easier to chew and swallow.
- Moisten Food: Add sauces, gravies, or dressings to your food to make it easier to swallow.
- Good Oral Hygiene: Maintain good oral hygiene to prevent infections and cavities.
