Understanding Mouth Ulcers: Causes, Symptoms, and Treatments
Mouth ulcers are painful sores that can develop anywhere inside the mouth. They affect individuals of all ages and often take time to heal. Since multiple factors can contribute to their occurrence, proper diagnosis is vital for effective management. This article explores common signs, potential causes, and available treatment options for mouth ulcers.
Causes
Many factors, including genetic predisposition, can increase the likelihood of developing mouth ulcers. Several triggers may activate or worsen the condition, such as:
Dental appliances like braces
Nutritional deficiencies including vitamin B9, B12, iron, or zinc
Stress and emotional strain
Use of mouthproducts containing SLS or sodium lauryl sulfate
Allergic reactions to oral bacteria
Infections like herpes, viral, or fungal infections
Hormonal changes during menstrual cycles or pregnancy
Lack of sleep
Consumption of acidic foods like citrus, coffee, berries, pineapple, or chocolate
Minor injuries from dental procedures, sports, bites, or aggressive brushing
Occasionally, recurrent mouth ulcers may signal underlying health issues, so consultation with a healthcare professional is recommended if problems persist.
Additional causes include:
Celiac disease
Diabetes
HIV/AIDS
Inflammatory bowel conditions like ulcerative colitis
Autoimmune diseases such as lupus, Behcet’s disease, or oral lichen planus
Signs and Symptoms
Symptoms vary based on the cause but generally include:
Painful sores that may be yellow, red, or white
Lesions inside the mouth, on the tongue, cheeks, or lips
Increased pain during eating, drinking, or talking
Most mouth ulcers are not contagious, except those caused by infections like hand, foot, and mouth disease. Common types include minor, major, and herpetiform canker sores, with minor healing in 1-2 weeks, major taking longer and possibly scarring, and herpetiform forming clusters that resolve within a month.
When to See a Doctor
Seek medical care if ulcers are unusually large, last over three weeks, extend to the lips, cause severe difficulty in eating or drinking, or are accompanied by fever, diarrhea, or unmanageable pain. Also, if new ulcers appear before old ones heal or if sores are painless, professional evaluation is essential.
Treatment and Home Remedies
Generally, mouth ulcers resolve with minimal intervention unless linked to other health issues. Effective remedies include:
Saltwater rinses: Mix a teaspoon of salt in warm water, rinse for a few seconds, and repeat several times daily to help dry out sores.
Honey application: Applying honey directly on ulcers several times daily can soothe and reduce inflammation due to its antibacterial properties.
Baking soda rinse: Dissolve a teaspoon of baking soda in half a cup of water, swirl in the mouth, and spit out to help balance pH and reduce swelling.
Dietary Recommendations
Opt for soft, bland foods that are easy to swallow and do not irritate the mouth. Cold foods and beverages like ice cream, iced tea, or cold water are calming. Avoid spicy, salty, acidic, or hard foods such as nuts, seeds, citrus fruits, coffee, and tomatoes to prevent aggravating the ulcers. Incorporate mashed foods or smoothies to ease discomfort.
