Hi Treatment for gap (Midline diastema) depends on amount of gap between your teeth...If the gap is less than 2 mm then you can go for tooth coloured composites,laminates,veneers,crowns.In this the treatment ll complete within 2 to 3 appointments If the gap is more than 2 mm  then orthodontic ( braces ) treatment is the only option....In this the treatment period will be 8_ 12 months Complete clinical examination is necessary to check for treatment option and to rule out the causes of gap(Midline diastema)...

Yes, very much possible with aligners(invisible removable braces) or with veneers

Without damaging your natural teeth we can do tooth colored filling if you don't have time.
