Hii... Braces / Aligner treatment is advisable after age of 13-14. & It is totally normal to have bigger teeth in front because it is the 1st permanent teeth to erupt in oral cavity. Adjacent teeth are still milky tooth that's why it looks weird. In this age , it's called ugly duckling stage. It happens with everyone so don't worry it will be corrected automatically..& if not , u can go fo treatment later on.
