Children born with a cleft lip and/or palate may develop dental problems and require regular appointments with an orthodontist. Orthodontists work together with a team of dentists to address all their dental needs. Children born with a cleft are more likely to have fewer teeth (hypodontia) or extra teeth (supernumerary) than children without a cleft. They are also more likely to have a narrow top jaw and the teeth that do grow may become crowded and crooked. Crooked teeth can be hard to clean properly and so a child born with a cleft may be more likely to get tooth decay. People born with a cleft lip and/or palate who didn’t have orthodontic treatment when they were young can still benefit from having orthodontic treatment as an adult.
