Aphthous Ulcer (Canker Sores / Mouth Ulcers) – Introduction and Symptoms
Aphthous ulcers are small, painful, shallow open sores (ulcers) that develop inside the mouth — on the inner cheeks, lips, tongue, floor of the mouth, gums, or soft palate. They are the most common type of oral ulcer and are not contagious (unlike cold sores caused by herpes). They usually heal on their own in 7–14 days, but can be very uncomfortable.
Common Symptoms
- One or more round/oval ulcers with a white/yellowish-gray center and bright red inflamed border
- Sharp, burning or stinging pain, especially when eating, drinking, talking, or brushing teeth
- Pain worse with spicy, salty, acidic, or hot foods/drinks
- Difficulty eating or speaking in severe cases
- Mild swelling of nearby lymph nodes (occasionally)
- Recurrent episodes (recurrent aphthous stomatitis) in some people
Triggers / Risk Factors (often multiple)
- Stress / emotional upset
- Minor trauma (biting cheek, dental work, hard toothbrush)
- Nutritional deficiencies (iron, B12, folate, zinc)
- Food sensitivities (citrus, chocolate, nuts, gluten in some)
- Hormonal changes (menstruation)
- Weakened immunity
- Family history
Important Note Most aphthous ulcers are self-limiting and benign. However, see a doctor/dentist if:
- Ulcers last >2–3 weeks
- Very large (>1 cm) or unusually painful
- Frequent recurrences (more than 3–4 times/year)
- Accompanied by fever, swollen glands, skin/genital ulcers, eye inflammation (may indicate Behçet’s disease, Crohn’s, celiac, or other systemic condition)
Homeopathy is commonly used for aphthous ulcers and many people report good symptomatic relief (pain reduction, faster healing, fewer recurrences) when the remedy matches the individual picture. It is supportive and works best when individualized.
Homeopathic Medicines (Most Commonly Used for Aphthous Ulcers)
Take 3–5 pellets under the tongue, away from food/strong smells. Stop as soon as significant improvement occurs. Do not repeat unnecessarily. Consult a qualified homeopath for best matching and potency — especially for frequent/recurrent cases.

Ulcers bleed easily on touch or when eating, very sensitive to touch/slightest pressure, hot mouth, child cries before urinating (common keynote), aphthae in children, fear of downward motion. Usual dose: 30C, 3–5 pellets 2–3 times daily during active ulcers.

Quick Supportive Tips
- Avoid spicy, acidic, salty, hot foods during active ulcers
- Rinse with salt water or baking soda solution (1 tsp in glass warm water) 3–4 times/day
- Use soft toothbrush, avoid trauma
- Supplement B12, iron, folate, zinc if deficient (after blood test)
- Manage stress (very common trigger)
If ulcers are very frequent or severe, consult both a homeopath (for constitutional treatment to reduce recurrences) and a physician/dentist to rule out underlying systemic causes.
