Will all the teeth realign back to its original state if teeth are restored to how it was? have tmj, tooth bonding, dry mouth, clenching, psych meds

Invisalign: I'm not sure i understand the question but, if you get orthodontics done now at 25yrs old, they usually can be restored to its original state, except if there are severe issues (ie; major cross-bite, open bite) these may need orthognathic surgery. If you don't wear a retainer at night after treatment is done, they will rebound & get bad again.

Maybe: First it is important tp choose a dentist that is trained to treat TMJ problems. Your teeth can be restored but you may need to have orthodontics if you want to move teeth to a different position. Finally dry mouth is a challenge to control with the assistance of your dentist. Fluoride will help resist decay that is common with dry mouth and orherproductscan help. Your dentist can advise you.

They can move: Teeth will generally respond to the sum of forces being applied to them throughout life. Once the forces all balance out, relative stability follows but if orthodontic treatment or restorative dentistry contributes to imbalance of those forces, they will move in such a way as to regain balance. Parafunctional habits can certainly add contributory force. Best to wear a retainer if in doubt.
