Is normal to get a loose tooth just after getting braces?

Yes: The bone is starting to remodel around the teeth due to the pressure, and that loosens them up a bit.

Yes: The teeth feel loose because the braces are encouraging tooth movement. The wires creat pressure in one area that cause bone to resorb. On the opposite side of the tooth, bone will be deposited. The loose tooth feeling is only temporary.

Yes: All the teeth may get a little loose although you may just notice one that is looser. The bone cells on the side of the tooth are resorbed allowing the tooth to move. New bone then grows on the other side. This takes time and is the reason retainers are used after the teeth are straight.

Yes: Teeth get loose because the ligament surrounding the tooth gets stretched. It is called the periodontal ligament. During the course of treatment you may notice some looseness. Make sure your orthodontist checks your teeth to make sure they are not too loose. If so they will need to make an adjustment on your braces.

Normal: That's how we orthodontists move teeth. We cause bone on one side of the tooth to dissolve away, while bone on the other side is built up. Looseness should be minimal and transient. Why not ask your orthodontist (i hope you're seeing a specialist) to check it for you.
