Swelling on the top of the mouth may be related to lipitis, allergic reactions, trauma and other causes.
1. Lipitis: Inflammatory reactions occur in the lips caused by chronic irritation, excessive sunlight exposure, and other factors, resulting in symptoms such as swelling and pain in the lips.
2. Allergic dermatitis: due to lip contact with lipstick and other cosmetics, can cause an allergic reaction in the lips, swelling and pain in the mouth.
3. Trauma: If the mouth is burned, bitten and other external injuries, can lead to damage to the mucous membrane of the lips, mouth redness, swelling, pain and other phenomena.
It is recommended that those who have swollen mouths go to the hospital in time to clarify the cause of the disease and carry out standardized treatment under the guidance of the doctor, so as not to delay the condition.
