Ice Chips: Sucking – not chewing – on ice chips immediately before and after each treatment session since this might protect your tissues. (For some flavor, you can suck on frozen fruit.)
Saltwater Rinses: Adding saltwater rinses to your daily oral care routine might also help prevent or reduce mucositis' severity.
Dietary Changes: Spicy, salty, acidic, caffeinated, dry, or hot foods can irritate your sore tissues, so it's best to avoid them.
The Stanford Cancer Center recommends such soft, non-irritating foods as milkshakes, smoothies, puddings, oatmeal, pasta, and mashed potatoes. High-protein soft foods, like yogurt, are particularly good food choices.
Seedless, high-water fruits are recommended, and pureeing foods such as vegetables and fruits can also make them easier to eat.
Foods slathered in olive or canola oil can also help you consume small bites by providing some slipperiness.
Beverage Choices: Stay hydrated by increasing your fluid intake, especially by drinking more water. Decaffeinated warm tea can be a comforting drink. Avoid caffeinated beverages and alcohol.
Oral care: Avoiding alcohol also applies to your mouthwash, so find an alcohol-free product.
It's important to your overall health to maintain an oral health care routine. Gently brush your teeth after each meal or snack using a mild, fluoridated toothpaste and a soft-bristle toothbrush. As gentle as possible, floss your teeth at least once a day.
Avoid putting any tobacco products anywhere near your mouth – i.e., don't smoke or chew.
One more thing: Your dentist might suggest a solution known as magic mouthwash, which includes a mixture of over-the-counter or prescription anesthetic, antacid, antibiotic, antihistamine, or antifungal ingredients. (With this mix, you can see why it's also called magic mud.)
