When do teeth stop growing?

Do teeth stop growing?

• I know that some parts of the body grow constantly throughout your life. Some parts grow, shed/die, and are constantly replaced. Some parts don't change from when you are born. Teeth is my query. Do they grow to the point where we consider them fully grown? how do they know how long they should be? Or do they grow constantly, but are continuously (albeit very slowly), and worn down evenly to the same level as their neighbouring teeth? I just find it strange, that given the great asymmetry that goes on with the human body, that a row of teeth nearly always meet up in a nice line.

• Answer:

  The human body has an astounding level of symmetry in all areas other than the the deep viscera. Once you get an adult tooth grown in, that;s it- it is your tooth forever. It does not do any more growing, maturing- that's why it is so important to take such good care of them. There is a short growth period in children that still have their juvenile teeth. Their adult teeth form within the jaw and eventually begin to push out- this causes the "baby" tooth to loosen and fall out before it is permanently replaced.
