How To Make Buck Two Front Teeth In Line With The Rest of Teeth? (photo)

Orthodontics, either regular braces or Invisalign will move your larger front two teeth back in line with your other teeth.  The orthodontist may have to sand off a little to make your front two teeth narrower so there is enough room to do that.

If you think that your front two teeth are just to big (wide, thick, shape, etc.), then you could have porcelain veneers placed on them to make them smaller.  However, this would require some tooth preparation (drilling) on your front two teeth.

If it is the position of the teeth you do not like then orthodontics would be the first choice of treatment.  If it is the shape of the teeth, then contouring prior to orthodontic treatment can be done.  Otherwise, placing veneers would easily  solve the problem also. It depends upon how patient you are. Orthodontics could take up to a year, while placing veneers could be done in 2 weeks. 

From your photo it looks like you would be an excellent candidate for invisalign orthodontic aligners.  They can also straighten the mild crowding of your lower front teeth.
