Disease description:

A sudden lump has appeared on the roof of my mouth. I think it might be oral mucosal inflammation, but I'm not sure. Could you please tell me what could cause swelling on the roof of the mouth?

Swelling in the oral palate can occur after consuming spicy, irritating, or excessively hot foods, leading to redness, blood blisters, and pus-filled blisters in the maxillary region. Allergic reactions caused by eating seafood or taking certain medications may also result in swelling in the upper jaw area, which requires antihistamine treatment. In addition to medical treatment, patients should maintain good hygiene habits, rinse their mouth after meals, brush teeth regularly in the morning and evening, minimize consumption of sweets to avoid worsening the condition, and avoid staying up late.
