Yes. For braces to work, pressure from the wire has to loosen teeth so they can be pushed or pulled to a new location. As teeth shift, some cells have to break down so new bone cells can grow in their place to support the teeth in their new positions. This process can take several weeks. While you’re waiting for this bone regeneration to occur, it’s totally normal for teeth to feel loose. Although this can feel very disconcerting, don’t worry – your teeth are not going to fall out from your mouth.
