Kenacort 0.1% paste is an oral buccal paste containing triamcinolone acetonide 0.1% formulated in an adhesive base for application to mouth sores such as aphthous ulcers. As a topical corticosteroid, it reduces local inflammation, swelling, and discomfort by suppressing inflammatory mediators in the mucosa. The paste adheres to the lesion, creating a protective film that helps symptom relief and healing when applied directly and left undisturbed, typically avoiding food or drink for at least 30 minutes afterward. Clinical studies support its efficacy for minor aphthous stomatitis compared with non‑steroid alternatives like aloe vera gel.
