Can roots of a tooth fuse to the bone?

It is very likely that your k-9's roots are fused to bone and unmovable.  This is why I would recommend going to a cosmetic dentist to have your k-9's cosmetically restored with veneers or crowns.  I wouldn't waste time moving teeth that really don't want to move, when a cosmetic dentist can fix them permanently and perfectly in 1 or 2 appointments.  Good luck to you and I hope this helps.

Teeth can become fused to bone, medically termed ankylosis. If true ankylosis has occurred, orthodontic tooth movement will not be possible. Although true that impacted teeth are harder to retrieve as time goes on, I would not automatically rule it out and assume ankylosis has occured. Certain films will help in diagnosing this issue, and also the position of the tooth is important in determining whether or not it's feasible to go after it an bring it in. I would recommend seeing an orthodontist and have her/him comment on the possibility of bringing this tooth in. Whenever possible, it's always best to try maintain our own natural teeth. Good Luck!
