Do teeth remain stable all life long after the orthodontic treatment?
In some cases, modifications of teeth positions can occur after the interruption of the use of retention appliances. These alterations are due to changes of the bones and muscles of the face that happen as time goes by. Just as the wrinkles and stains on the skin, teeth can also change position during life span. This is why it is important not to miss review appointments in which the dentist observes the evolution of the teeth. If necessary, he/she can compensate these alterations, without the need for a new appliances.
