Canker sores treatments reduce eating pain effectively through topical anesthetics, protective coatings, anti-inflammatory rinses, and dietary adjustments that numb sores, shield them from food friction, and lower inflammation within hours. OTC gels with lidocaine/benzocaine, corticosteroid pastes, and salt/baking soda rinses enable comfortable meals while accelerating 7-14 day healing.
Topical Anesthetics Numb Immediately
Lidocaine or benzocaine gels applied 4x daily before meals deaden nerve endings, blocking food contact pain for 1-4 hours. Orajel and Anbesol formulations create barrier against acidic/spicy irritants, restoring eating ability Day 1.
Protective Coatings Shield from Friction
Film-forming liquids (Zilactin, Gly-Oxide) and hydrocolloid patches form moisture-resistant barriers preventing tongue/cheek abrasion during chewing. Milk of magnesia dabbed 3x daily neutralizes acids; aloe vera rinses soothe while coating sores.
Anti-Inflammatory Agents Reduce Swelling
Triamcinolone acetonide 0.1% paste or fluocinonide gel applied post-meal shrinks lesions 30-50% within 3 days, easing pressure pain. Ibuprofen (400mg) 30 minutes before eating controls inflammation systemically.
Dietary Modifications Minimize Irritation
Soft/bland foods (yogurt, mashed potatoes, smoothies) avoid mechanical/chemical trauma; straws bypass sore contact with beverages. Ice chips or popsicles numb locally; B12 supplements (1000mcg daily) speed resolution even without deficiency.
Natural Adjuncts Accelerate Relief
Honey (unpasteurized, 4x daily direct application) provides antibacterial coating reducing secondary pain; baking soda paste neutralizes oral acids. Lysine (1000mg daily) shortens outbreak duration.
Conclusion
Canker sore treatments reduce eating pain through numbing agents, protective barriers, anti-inflammatories, and irritant avoidance enabling normal nutrition during 7-14 day healing.
