While fixing crossbites whilst jaws and teeth are still in the developing stage is easier, and less complex, it is possible for orthodontists for adults to fix crossbites in adults. Adults with mild to moderate misalignment may get away with traditional orthodontic braces, but in some cases, adults may require jaw surgery and other invasive solutions as part of their treatment plan. Most orthodontists will suggest multiple treatment options to fix more serious crossbites, including orthodontic braces to move the teeth back into the correct position, using an expander to widen the jaws and a combination of aligners.
