Are teeth always shifting?

Yes: Teeth will continue to shift throughout your life, even if you've never had braces. That's why it's always a good idea to get missing teeth replaced. It will help stabilize things. I also recommend that my adult patients have orthodontic retainers made if they notice shifting of their teeth later in life.

Yes: Nothing in your body stays exactly the same from one day to the next. Teeth will continue to shift due to biting forces, muscle forces, and wear and tear.

It depends: Teeth shift due to periodontal teeth pressure from wisdom teeth best is to check with your dentist.
