Canker Sores: A Guide To Remedies And Treatments
Summary: Canker sores are small but painful mouth ulcers that can make eating and speaking uncomfortable. This guide explains their causes, symptoms, and effective home and medical treatments to relieve pain, speed healing, and prevent recurrence.
Introduction
Canker sores, or aphthous ulcers, are among the most common oral lesions, affecting up to 20% of the population at some point in their lives. They appear as round or oval ulcers with a white or yellow center and a red border, typically on the inside of the cheeks, lips, or tongue. While not contagious, they can cause significant discomfort, often making eating and speaking difficult. Episodes may last from 7 to 14 days, with some individuals experiencing recurrent outbreaks triggered by factors such as stress, hormonal changes, or certain foods.
Causes
Stress and Anxiety – Emotional stress can affect the immune system, making the mouth more vulnerable to ulcers.
Hormonal Changes – Fluctuations during menstruation, pregnancy, or puberty may increase susceptibility.
Local Trauma – Biting the inside of the cheek, irritation from braces or dentures, or harsh tooth brushing can injure oral tissue.
Dietary Triggers – Citrus fruits, tomatoes, chocolate, coffee, and spicy or acidic foods may irritate the mouth and trigger sores in sensitive people.
Immune and Nutritional Factors – A weakened immune system or deficiencies in vitamin B12, folic acid, iron, or zinc can slow healing and cause frequent recurrences.
Genetic Link – A family history of recurrent mouth ulcers may indicate a genetic predisposition.
Symptoms
Small ulcers – Usually round or oval with a red border and a white or yellow center. They often appear on the inside of the cheeks, lips, tongue, or soft palate.
Pain and discomfort – Can range from mild irritation to sharp, stabbing pain, especially when chewing, speaking, or eating spicy, salty, or acidic foods.
Sensitivity – A burning, tingling, or prickling feeling may occur in the area one to two days before the sore becomes visible.
Swelling – The surrounding tissue may appear slightly swollen or inflamed.
Difficulty eating or speaking – Larger or multiple sores can make basic mouth movements uncomfortable.
Possible fever or fatigue – Rare in mild cases, but severe outbreaks may cause general malaise.
Remedies And Treatments
1. Home Remedies
Salt water rinse – Mix one teaspoon of salt into a glass of warm water and gently swish in the mouth for 30 seconds. This helps cleanse the sore, reduce irritation, and promote healing. Repeat several times a day.
Aloe vera gel – Applying pure aloe vera gel directly to the sore may soothe pain and reduce inflammation. Some studies suggest it can help speed healing, but results vary.
Baking soda rinse – Dissolve half a teaspoon of baking soda in a cup of water and use as a gentle rinse. It may help neutralize acids in the mouth, though evidence is limited. Avoid rubbing baking soda directly onto the sore.
2. Over-the-Counter Options
Oral anesthetics – Gels or sprays containing benzocaine or lidocaine can numb the sore temporarily, easing pain during eating and speaking.
Anti-inflammatories – Nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen can help reduce swelling and discomfort.
Topical protective pastes – Pharmacy products that form a thin film over the sore can shield it from irritation and aid healing.
3. Dietary and Lifestyle Support
Avoid irritating foods – Stay away from spicy, acidic, salty, or crunchy foods that can worsen pain or slow recovery.
Stay hydrated – Drinking plenty of water keeps the mouth moist and supports the healing process.
Gentle oral hygiene – Use a soft-bristled toothbrush and alcohol-free mouthwash to reduce bacteria without aggravating the sore.
When To See A Doctor
Most canker sores heal on their own, but you should seek medical advice if any of the following occur:
Persistent sores – If a canker sore lasts longer than two weeks without signs of healing.
Frequent or recurrent outbreaks – Multiple episodes in a short period may indicate an underlying condition.
Severe pain or additional symptoms – If the pain is intense or accompanied by fever, difficulty swallowing, swollen lymph nodes, or unusual bleeding.
Unusual appearance – Sores that are unusually large, spread beyond the typical areas, or look different from normal canker sores.
