What to eat when I have ulcers in my mouth to soothe and heal

4 min read

According to the Cleveland Clinic, most mouth ulcers, or canker sores, heal on their own within one to two weeks, but pain can make eating difficult. Learning what to eat when I have ulcers in my mouth can significantly reduce irritation and accelerate the healing process by providing necessary nutrients without causing further discomfort.

Quick Summary

This guide details the best dietary choices for soothing and healing mouth ulcers, focusing on soft, non-acidic, and nutrient-rich foods, while also outlining foods and drinks to avoid that can aggravate sores and delay recovery.

Key Points

  • Soft Foods: Choose soft, bland foods that are easy to chew and swallow, such as yogurt, mashed potatoes, and scrambled eggs, to avoid irritating the sores.

  • Avoid Irritants: Steer clear of spicy, salty, acidic, and crunchy foods that can cause pain and inflammation, delaying the healing process.

  • Boost Key Nutrients: A diet rich in B vitamins (especially B12), iron, and zinc can support faster tissue repair and prevent recurring ulcers.

  • Stay Cool and Hydrated: Drink plenty of cool water to prevent dry mouth and irritation, and let hot foods and drinks cool to a lukewarm temperature before consuming.

  • Utilize Soothing Remedies: Incorporate natural remedies like plain yogurt with probiotics, raw honey, or a saltwater rinse to soothe discomfort and fight bacteria.

  • Use a Soft Brush: Practice gentle oral hygiene with a soft-bristled toothbrush to avoid further injury to sensitive mouth tissues.

  • Consult a Professional: If ulcers are persistent, unusually large, or come back frequently, seek medical advice to check for underlying health issues.

Mouth ulcers, also known as canker sores or aphthous ulcers, can turn simple activities like eating and drinking into painful ordeals. The tiny sores expose nerve endings, making them extremely sensitive to temperature, texture, and taste. Adopting a temporary diet of soft, bland foods can provide comfort and ensure your body receives the nutrition it needs for a quick recovery. Avoiding foods that trigger irritation is just as crucial for preventing further inflammation and pain.

Soothing and Healing Foods for Mouth Ulcers

Soft and Bland Foods

  • Yogurt and other plain dairy products: Plain yogurt, especially with live probiotics, can help balance the bacteria in your mouth. Milkshakes, cottage cheese, and other soft dairy products are also soothing and gentle on the sores.
  • Eggs: Scrambled, poached, or soft-boiled eggs are an excellent, high-protein food source that requires minimal chewing.
  • Well-cooked vegetables: Mashed potatoes, pureed squash, and steamed carrots are soft, nutritious, and easy to eat. Creamed spinach or corn are also good options.
  • Smoothies and shakes: Blending non-acidic fruits like bananas, melons (honeydew, cantaloupe), and papaya with milk or yogurt creates a nutrient-dense meal that bypasses the sores.
  • Oatmeal and cooked cereals: Thinned oatmeal and other cooked cereals like cream of wheat are soft and easy to swallow, providing energy without irritation.
  • Applesauce and soft fruits: Applesauce is a gentle, soothing option. Other soft fruits, such as bananas and peeled, baked apples, are also well-tolerated.
  • Soft protein sources: Silken tofu, soft fish, or tender, ground meats can provide essential protein for tissue repair without being tough to chew.

Nutrients for Faster Healing Certain nutritional deficiencies, particularly in B vitamins, iron, and zinc, are linked to recurring mouth ulcers. Incorporating foods rich in these nutrients can aid healing and potentially prevent future outbreaks.

  • Vitamin B12: Found in eggs, milk, and fortified cereals.
  • Folate (Vitamin B9): Rich sources include leafy greens, legumes, and nuts.
  • Iron: Found in well-cooked spinach, lentils, and fortified grains.
  • Zinc: Present in yogurt, soft tofu, and well-cooked chickpeas.
  • Vitamin C: Non-acidic sources like papaya and bell peppers support immune function and tissue repair.
  • Probiotics: Eating plain yogurt with live cultures can help balance oral bacteria.

Foods and Drinks to Avoid

To prevent further pain and speed up recovery, it is crucial to steer clear of certain food and drink categories:

  • Spicy and Salty Foods: Chili powder, hot sauce, jalapeños, and high-salt snacks like chips or pretzels can sting the open sores and worsen inflammation.
  • Acidic Foods and Drinks: Citrus fruits (oranges, lemons, grapefruit), tomatoes, and carbonated beverages can irritate ulcers and delay healing.
  • Hard and Crunchy Foods: Toast, crackers, nuts, and raw vegetables can scrape against the sores, causing pain and further damage.
  • Hot Beverages: Piping hot coffee, tea, or soup can irritate the sensitive nerve endings in the ulcers. Opt for lukewarm or cool beverages instead.
  • Alcohol: Alcoholic drinks can dehydrate the mouth and irritate the ulcer sites, slowing down the healing process.

Soothing Foods vs. Irritating Foods: A Comparison Table

Feature Soothing/Healing Foods Irritating/Inflammatory Foods
Texture Soft, mashed, pureed, or liquid Hard, crunchy, rough, or abrasive
Acidity Low or neutral pH (alkaline) High acidity
Spice/Flavor Bland, mild Spicy, salty, or heavily seasoned
Temperature Cool or lukewarm Very hot or very cold
Examples Plain yogurt, mashed potatoes, scrambled eggs, bananas, smoothies Chips, toast, citrus fruits, tomatoes, spicy curries, coffee
Nutritional Impact Provides essential vitamins and minerals for tissue repair Can contribute to nutrient deficiencies and delay healing

Additional Tips for Relief and Healing

Beyond dietary adjustments, several simple practices can offer additional relief:

  • Rinse with saltwater: A rinse with warm salt water can reduce inflammation and help keep the area clean. Mix a teaspoon of salt into a glass of warm water and rinse for 30 seconds.
  • Use a soft toothbrush: Gently brushing with a soft-bristled brush can prevent further irritation to the delicate tissues.
  • Stay hydrated: Drinking plenty of cool water throughout the day can help prevent dryness, which can worsen symptoms. Using a straw for drinks can help bypass painful sores.
  • Apply honey or coconut oil: Raw honey and coconut oil have natural antibacterial and anti-inflammatory properties. Dabbing a small amount on the ulcer can form a protective barrier and promote healing.

Conclusion

Living with mouth ulcers can be uncomfortable, but adjusting your diet is a powerful step toward managing the pain and promoting a faster recovery. By focusing on soft, bland, and nutrient-dense foods, and actively avoiding irritants like acidic, spicy, and crunchy items, you can provide your mouth with a calm environment to heal. For persistent or severe ulcers, consulting a healthcare provider is recommended to rule out any underlying conditions. By following these dietary and care recommendations, you can minimize discomfort and get back to enjoying your meals.
