Removable appliances are custom-fitted to shift your teeth or to hold them in place. They can be used for simple malocclusions where one or more teeth must be tipped back into their correct position. Because removing this type of device is easy, you might be tempted not to wear it exactly as the orthodontist prescribes. However, it’s essential to resist this temptation. Otherwise, your teeth could return to their original position. Initially, your eating and speaking may be affected, and you may notice increased saliva flow. However, these symptoms will soon diminish as you adjust to the appliance – usually within 2-3 days.
