An orofacial (or-oh-FAY-shul) cleft is when a baby is born with an opening in the lip and/or roof of the mouth (palate). Cleft lip and cleft palate happen is one of the most common birth defects. Both cleft lip and cleft palate are treatable. Most kids can have surgery to repair them within the first year or two of life. Children with a cleft lip and palate often have dental problems. These can include small teeth, missing teeth, extra teeth (called supernumerary), or teeth that are out of position. They may have a defect in the gums or alveolar ridge (the bone that supports the teeth). Ridge defects can displace, tip, or rotate permanent teeth or prevent permanent teeth from coming in properly. Regular visits with a pediatric dentist who specializes in cleft lip and palate are important. The dentist will check a child's mouth growth and development, identify any problems, and make treatments when needed.
