Dear friend,that means u have a spacing among your teeth.Spacing can be corrected by orthodontic treatment which is very reliable and trustworthy treatment.It requires for approximately 1 year to correct your spacing.Cost depends upon the type of wire appliance actually so difficult to give you quotation, there's another treatment called as smiiledesign by composite fillings but 1 St one is natural and best treatment.

There are various options. U need to visit a dentist to understand that.
