Density is not directly related to tornadoes, but it does play a role in how they form.

Cold air is denser than warm air and dry air is denser than moist air. When a dry and moist or a warm and cold air mass collide the less dense air mass is forced upwards and the moisture in it condenses. It is by the process that the thunderstorms that spawn tornadoes usually form.
