Unfortunately your pictures are not appearing, but your description is detailed enough at this point.
Hay eating is the number one thing that maintains a rabbit’s teeth. In most cases, increasing hay consumption will help teeth maintenance and deter the need for veterinary intervention (i.e., routine filings). That being said, there are cases of rabbits whose teeth, due to genetics/trauma/other, do not line up, therefore, regardless of how much hay they eat, certain teeth surfaces will not get ‘sanded’ down by chewing/grinding and therefore will grow out and need that veterinary intervention.
Since your rabbit is so young and still has a lot of growing to do, I would not draw any conclusions on whether your rabbit will permanently need intervention — I’d focus on increasing hay consumption as much as possible. There are cases where a rabbit needs some intervention when younger, but then they “grow out of it” as they get bigger. My Wick used to get monthly teeth grindings, but has now been grind-free for a couple years at this point.
