You may know them as retainers. We refer to them as expansion appliances as they are very effective at widening the upper jaw to create space when a patient presents with a case of ‘crowded teeth’.


For younger patients

Expansion appliances are very useful in dealing with bite discrepancies and are often a suitable alternative to removing teeth. We typically employ this treatment with younger patients who are growing and whose bones are more suited to change.
