Hello mam..it’s quite normal for ur teeth to be very slightly mobile during fixed braces treatment. It’s a process of which the tooth movement occurs.
U don’t have to worry unless u have an exaggerated mobility of teeth
Next Steps
Visit ur dentist every month for check up of ur braces without fail
Health Tips
Maintain soft healthy diets, take a multivitamin supplement, use a fluoridated mouth wash after every meal. Cheers
