2 missing teeth. I'm getting braces and my dentist wants to make 2 gaps for those to teeth, but I'm not sure it would look nice

So the two teeth I'm missing are the top and my two front teeth are in between them. My orthodontist wants to make two gaps next to my two front teeth with braces then to where a retainer with fake teeth on them until I'm old enough to get implants. Is the gap going to show before I get the retainer? ( and I can't file my teeth next to them because they are too short)
