Huge gap means a missing tooth.Get evaluated by a dentist with the help of x-rays. If there are no missing teeth orthodontic correctuon will be the ideal option. If the gap is more and a tooth is missing then implant or fixed bridge might be done.

U can but get the X ray called opg or CBCT done in order to decide the proper treatment plan .

Alternatively option is closure of space with Orthodontic appliance but it all depends on the clinical situation and bone conditions

Orthodontic (clips) treatment might be considered to close that space in a natural way instead of going for an artificial tooth. Please consult an orthodontist for proper diagnosis and treatment plan

There are multiple treatment options to correct your problem but the best options applicable for your case can be delineated only after a proper clinical evaluation and a few X-rays. Try to schedule an appointment with the dentist for a proper clinical evaluation so that the right options can be explained to you. Alternatively you can post a clinical picture on Practo for an online consultation with the specialist. Orthodontic treatment whether using braces or clear aligners can be used to move the teeth in such a way that all the teeth approximated to achieve a better smile. But this usually takes one to one and half years as the bone density increases with age and makes the teeth movement slower. The shorter duration treatment can be crowns to fill the gap and a dentist who performs a clinical evaluation can guide you about that better. Regards.
