The optimal time for correcting an underbite is around age 4. If an underbite is detected when all baby teeth have erupted, prompt treatment ensures that by the time baby teeth are shed and permanent teeth emerge, the underbite will be corrected. This approach also maximally prevents excessive jaw protrusion that could affect facial aesthetics.
Early detection and correction of children's bad habits and dental issues are crucial for permanent tooth development. Regular dental check-ups prepare for the normal replacement of permanent teeth.
