It is good to be aware of the shape and alignment of your teeth.
Next Steps
First get a dental check up soon.
2 options are there for correct your teeth,
1. Get braces treatment - solution in 8 to 12 months with monthly appointments and without harming your teeth (more advisable as you are young enough to get it done)
2. If your only front teeth are problematic then you can get Teeth Caps on those teeth. In this, the dentist will shape your teeth a bit and then put a cap on it. (faster treatment, around 1 week)
