There is a crack in my front tooth, and the tooth next to it is very small. I want to correct it. What can I do to correct it? But I just want to make it simple and make a veneer repair. ...

Think about it. Your two front teeth are much bigger than your two. How big will it be to close the gap with veneers? Isn't your mouth full of front teeth? Too ugly

I suggest you do orthodontics, close the gap between the two front teeth, and then do crown restoration on the two small lateral incisors. It may take a little longer, but the long-term effect is good. Go to the stomatological hospital to do it. The small clinic now is really incredible.
