Micrognathism (or Micrognathia) is a condition where the jaw is undersized. It is also sometimes called "Mandibular hypoplasia".[citation needed] It is common in infants,[citation needed] but is usually self-corrected during growth, due to the jaws increasing in size. It may be a cause of abnormal tooth alignment and in severe cases can hamper feeding.[citation needed]
