SOLUTION
If heavy pressure is applied to a tooth, pain develops almost immediately as the PDL is literally crushed.
There is no excuse for using force levels for orthodontic tooth movement that produce immediate pain of this type.
If appropriate orthodontic force is applied, the patient feels little or nothing immediately. Several hours later, however, pain usually appears. The patient feels a mild aching sensation, and the teeth are quite sensitive to pressure, so that biting a hard object hurts.
The pain typically lasts for 2 to 4 days, and then disappears until the orthodontic appliance is reactivated. At that point, a similar cycle may recur, but for almost all patients, the pain associated with the initial activation of the appliance is the most severe.
