What physical forces causes a tooth to erupt?

| I had a bottom tooth (#18) removed and was told that there is a chance
of the upper neighboring tooth erupting.
Isn't the upper tooth held firmly in place by its roots? How can it
erupt when there are no physical forces
pulling down on it?

| teeth are designed to erupt as they wear down. when you are missing one
of the teeth the opposing erupts.
Sometimes depending on how your teeth are setup a portion of that tooth
is held by the opposing tooth but the rest of the time the tooth will
continue to erupt until it hits the gums. This can interfere with
function when you move your lower jaw side to side it will collide on
this tooth. If you do not restore the lower in a timely manner you will
not have room for the crown and may need to have root canal done on the
upper with a buildup and crown. and if you wait even longer you may
lose the upper opposing tooth as well.
My suggestion is if you have enough bone on the lower jaw that is above
the nerve get an implant.

Ya Alex. Maybe the orthodontists know--specifically. It makes sense
to me that lack of occlusal contact stimulates osteogenesis under the
roots. Of course the (super)erupting tooth will generally carry that
whole section of the alveolus coronally with it. But while I've seen
discussions of the changes in bone during orthodontic movement (a
relative increase in osteolysis in advance of a moving root; a relative
increase in osteogenesis behind) I don't know what exactly is going on
on a cellular level; ordinarily you would expect the alveolar bone
under a tooth out of occlusal contact to become less dense.
