Hi.... Best option is Orthodontic treatment but you can go with other options available like crown or composite build up

Hello, As u have not upload ur picture diagnosis n treatment may alter....as u don't want braces treatment..either u can go with crowns ( depending on the gap) But  ideal treatment is orthodontics treatment either with braces or invisalign

Hi If you could share a pic we can give you a more precise diagnosis and treatment plan. By the way it seems to be a condition called midline diastema. It can be best treated with an orthodontic appliance no need to go for braces. These days we also have something called Invisalign which is a plastic like appliance which you need to wear on your teeth and it's invisible. Depending on your case you might also need to go for a small surgery called frenectomy if the spacing is caused by a high freenum.
