Will Widening Dental Arch Will Make my Face Wider?

Don't worry.  Widening your dental arches does't make your face wider.  It will, however, make your smile fuller which is good.  Take a look at pictures of a couple of the most famous wide and full smiles, that of Julia Roberts and the late Farrah Fawcett.  They both show very wide and full smiles and I think you would agree that their faces don't appear wide.  The opposite of this are narrow arches that show dark shadowy spaces between the side teeth and the cheeks, not an attractive look.

Four bicuspid removal for ortho frequently leaves an unattractive smile line.  It can also cause or worsen sleep apnea and snoring as well as create TMJ problems and chronic headaches.  Correction of the smile could be evaluated before embarking on treatment by doing a diagnostic wax-up and temporarily placing an integrity composite in your mouth.  This will let you  see very closely how you will look before beginning treatment. 

It will add to total cost but will avoid a  result that could disappoint you.  I routinely do cosmetic mock-ups prior to veneers and full mouth reconstruction to avoid surprises.

No. Widening the dental arch with Invisalign
will simply expand your upper teeth. There is no skeletal movement and it will
not make your face wider.
