Since Vitamin B isn't providing relief, you can use targeted topical treatments. For immediate pain relief, especially before eating, apply a local anaesthetic gel containing lidocaine or benzocaine directly to the ulcer. To speed up healing and reduce inflammation, a topical corticosteroid paste like triamcinolone acetonide is highly effective. Antiseptic mouthwashes containing chlorhexidine gluconate can also prevent infection and promote recovery. Additionally, try rinsing with warm salt water and avoid spicy, acidic, or rough foods that irritate the sores. If your ulcers last longer than two weeks or recur constantly, please consult a healthcare professional for a personalised evaluation.
