Concern) Gap between teeth

Orthodontic treatment number 2... The wire maintaining the alignment broke, causing the teeth to shift, and I had a partial correction again, which created a space between the teeth... a black triangular space called a blantrangle. It's not severe, but after eating, food tends to get stuck there. Spicy red pepper...ㅠㅠ I looked it up online and found a method to fill the gap between teeth with resin. Has anyone tried a tooth gap filling treatment? I don't think it will be permanent, but I'm worried that a larger space might develop later. I'm also curious if it affects brushing or oral hygiene.
