When do adult teeth stop growing?

Occlusion: The teeth stop erupting when they hit the antagonistic tooth in the opposite arch. That is why it is important to replace missing teeth; if a tooth does not occlude with another tooth, it continues to grow, pulling the bone with it. That gives you a very uneven bite.

Depends: Adult teeth can continue to move through out your life. They usually stop vertical movement when they hit the opposite tooth of functioning partner. If you loose a tooth then the neighboring teeth will move to occupy the space both horizontally and vertically. Check with your dentist to see what is applicable to your specific situation.

Adult teeth: Individual permanent teeth stop growing when the tooth's root(s) are fully formed, and usually corresponds with tooth coming into occlusion with tooth in opposing jaw. 1st permanent tooth usually erupts about age 7, the last permanent tooth by late teens/early 20's. Teeth can tip and drift throughout life, but once fully formed do not continue to grow. If concerned, see an Orthodontist.
