Canker sore types and triggers
Canker sores, also called aphthous ulcers, are common painful lesions on the oral mucosa that challenge daily comfort. In dermatology practice, they are categorized by size, location, and whether they recur, guiding treatment choice. Triggers include stress, micronutrient deficiencies, hormonal changes, and minor trauma from brushing, smoking, or rough foods.
A balanced diet and good oral hygiene can reduce flare ups, particularly when ulcers are active. Early topical care is linked to shorter symptom duration in clinical observations across multiple clinics. Clinicians emphasize avoiding secondary infection by keeping tools clean and hands away, and by replacing damaged toothbrushes.
Dermatology care options
Topical corticosteroid gels reduce inflammation and speed relief for many patients, especially when applied promptly. Antiseptic mouthwashes lower the risk of secondary infection and plaque buildup, while also soothing irritated mucosa. Mucosal protectants and vitamin supplementation can support healing when deficiencies exist, particularly for athletes and heavy smokers.
Low level laser therapy is used in some Korean clinics to ease pain and accelerate recovery, based on patient responses. Mastic gum and propolis show anti inflammatory signals, though results vary by patient and specific ulcer characteristics. Some centers explore noninvasive modalities for resistant ulcers, always under medical supervision and with informed consent.
Preventive oral skin care
Daily routines like soft brushing, avoiding spicy foods, and staying hydrated help prevention and reduce pain duration during outbreaks. Mouth sprays with local anesthetics or soothing ingredients provide temporary relief during attacks and can be used as part of a larger care plan. Saline rinses and gentle antiseptics can maintain mucosal health between episodes and support healing when used consistently.
Emerging trends in Korea focus on stress management and nutrition to reduce recurrences and strengthen mucosal resilience. Clinicians monitor for persistent ulcers that may signal underlying conditions requiring referral to specialists. Education about avoiding trauma during brushing and bite guards for bruxism supports long term health and prevents future episodes.
