Advice about chipped tooth

[Shara13]

Hi, I would really appreciate some advice regarding my 9 year old daughters front tooth. She chipped a small horizontal piece off the bottom of her right front tooth today. She says it feels very jaggered when she runs her tongue across it.
It’s not very noticeable from the front, so I am wondering if I am able to leave it and eating will help flatten it out or is a dentist needed to help file it flat?
I will attach some pics to clarify.
Thanks so much in advance!

She'll probably continue to be annoyed by it. Get it smoothed by a dentist.
Also, take her to an orthodontist for an assessment of her apparently narrow arch.

Thank you very much for your reply. Could you please tell me more about the narrow arch? What ramifications can come from a narrow arch? Thank you once again for your time

I see her upper right lateral incisor is on the inside of her other teeth which means she probably has a narrow arch. Orthodontic treatment might be useful to widen her upper teeth at this stage. Go see an orthodontic specialist for an opinion.https://imgur.com/v1C0srA
