How, using Market Forces, can Excess Demand be extinguished?

-This is when Demand for the Good is Greater than the Supply. This happens when the Price is Below the Equilibrium Price. -If so, then the Price would be Forced Upwards as to Match the Demand, Supply must Increase. Only way to Reasonably Achieve that is Increasing the Price [Incentive] leading to an Equilibrium Point being Reached.
