If the mouth is accidentally scalded by hot water, it should be promptly cooled down. Initially, one can soak the affected area in cold water or apply a cold pack to reduce body temperature, dissipate heat, and alleviate pain. Subsequently, medication should be applied depending on the degree of the burn. If the scalded area only shows redness and stinging, one could disinfect it with iodine followed by an application of burn ointment to reduce swelling and promote healing. If clear blisters form, they can be punctured with a sterile needle to drain the fluid, then burn ointment should be applied to help reduce symptoms. During treatment, the affected area should avoid contact with water and spicy foods should not be consumed, both of which are beneficial for the healing of the wound.
