Bone loss: If you have bone loss, your teeth can shift more readily. Inflamed bone will also allow the teeth to loosen up. Hope you're being treated professionally for your dental issues.

Crooked teeth: Teeth can move slowly over time. This happens more frequently and to a greater extent in the presence of periodontal (gum) problems and a less than ideal occlusion (bite). I suggest you see your own dentist to determine if what you see reflects a problem that needs to be addressed or if your gums are healthy and your teeth are only slightly out of line but a variant of normal.

It's free: Why don't you go see a specialist Orthodontist about your tooth malposition. Initial Examination usually free. If you have gum disease your Dentist or a Specialist Periodontist may have to become involved. Gum disease exacerbates instability..
