I Really Don't Want Braces. How Can I Close a Gap Between my Two Front Teeth Without Braces? (photo)

This can be done in two ways.  The most common is bonding tooth colored filling material on one or both teeth.  It sounds easy, but only skilled dentists can make it look real.  With gaps a bit larger, or when fixing other issues like size or shape, porcelain veneers are another option.  This covers the front and sides of teeth and is more color stable and more durable than bonding composite fillings.

I agree with the other doctors. 

Composite bonding should be your best bet for such a small gap. That will be most conservative and fast treatment option as well.    You could also use invisalign but that may be overkill

Orthodontics (Invisalign) would be my first choice of treatment, however this would also require that you wear a retainer at night to keep the space closed after orthodontics is completed. A small space such as yours could be corrected by placing a direct composite (tooth-colored) filling. This would need to be maintained over the years but would provide a very quick solution to your problem.
