My premolars in back seemed to have shifted and are leaning inwards. they also seem to be pushed in. is there something i could do to straighten them again? it's worrysome.

Moving teeth: Yes orthodontics like invisalign can move it back . But you are probably missing a tooth and need to replace it or it will happen again. See you dentist for a permanent solution.

Need Consultation: Consult with a dentist that does orthopedic appliances in addition to orthodontics (braces).

Yes, worrisome : You need consultation with an orthodontic specialist. Teeth will get more crooked with age unless the malocclusion is corrected. Orthopedic rx, to is ineffective without surgery. Clear aligners can give you about 41% correction of minor problems. Go see someone who does this all day long every day and who has more than a weekend 's training at a holiday inn express.

Something can be don: This is a common problem. Very often the back teeth (premolars and molars) begin to cave in. The sooner you address the problem, the easier it is to fix. See an orthodontist.

Cause for concern: The teeth tipping inward is a sign of a general bite problem. The jaws widen as you go back. The lower jaw may want to close more forward, but can't as the teeth are in the way. Upper and lower arches must be expanded to make room to fit together, after the position and trajectory of closure are determined. How the teeth are positioned is less important than where they are positioned.

Ask an orthodontist: Collapsed posterior teeth can be addressed using invisalign or braces. Consult an orthodontist for a professional opinion with regard to your specific condition.
