Please get an xray done

Probably one of your milk teeth is over-retained.

Did you have a fall or any trauma on your front teeth? If yes then u might require urgent treatment. If not then probably you require a clean up. Just get a check up done to clear all your doubts.

Mobility of the permanent teeth at your age is not desirable. Please visit the dentist as soon as possible for a proper clinical examination to evaluate the exact cause of this problem. The right treatment needs to be instituted immediately but can be suggested after rational diagnosis has been established. In the meanwhile make sure to maintain proper oral hygiene by meticulous tooth brushing and cleaning your tongue with your toothbrush only. Regards.
