Is it possible for a second molar to move into empty spot of first molar, even if it had a root canal treatment done on it years ago, but has failed?
Certainly - depending on how long the first molar has been out. If the missing tooth is an upper molar, the transition is easier. What makes it more difficult in the lower is that the ridge in the lower molar gets narrower with time and the wider root of the second molar has difficulty in moving forward. Of coarse, this movement only occurs by orthodontic appliances, so you should consult your orthodontist with these questions.I hope this helps.
