Interceptive orthodontic treatment is performed for problems that, if left untreated, could lead to the development of more serious dental problems over time. The goal is to reduce the severity of a developing problem and eliminate the cause. The length of later comprehensive orthodontic treatment may be reduced.
Examples of this kind of orthodontic treatment may include correction of thumb- and finger-sucking habits; guiding permanent teeth into desired positions through tooth removal or tooth size adjustment; or gaining or holding space for permanent teeth. Interceptive orthodontic treatment can take place when patients have primary teeth or mixed dentition (baby and permanent teeth). A patient may require more than one phase of interceptive orthodontic treatment.
