Strict Avoidance of Swallowing: "You must never swallow the Betnesol liquid after rinsing. Spitting it out ensures the steroid action remains completely localized to your oral cavity." Dietary Adjustments: "While the ulcers are healing, strictly avoid spicy, acidic (tomatoes, citrus), salty, or very hot foods and beverages. These cause intense chemical and thermal irritation to the raw tissue base, significantly delaying recovery." Toothpaste Check: "Switch to a mild, sodium lauryl sulfate (SLS)-free toothpaste. SLS is a foaming agent found in many commercial brands that can irritate the oral mucosa and trigger ulcers in sensitive individuals." Caution: "Do not use steroid gargles for more than 5–7 days. Prolonged use can alter the natural microbial balance of your mouth, potentially inducing a secondary fungal infection like oral candidiasis (thrush)." Red Flags: "Seek a direct medical review if an ulcer fails to heal completely within 14 days, if you develop a high fever, or if the pain becomes so severe that you are completely unable to swallow fluids."
