What can be done to correct my Buccal Corridor? I'm 27 YO Female. (photos)

As a matter of professional policy, I usually tend not to make determinations of beauty and cosmetic preferences. I feel that aesthetics are a highly personal matter, and should be considered on behalf of oneself. In your case however, I struggle to see anything other than an ideal smile, with balance and symmetry relative to the rest of your facial structure.Zoom whitening is the only cosmetic option I would advise towards, otherwise, you're definitely in the lucky category when it comes to dental aesthetics- and I don't often say that. Hope that helps.James Asaf, DDS

You have a beautiful smile! I recommend NO TREATMENT. If you want to do something, professional whitening would improve your brightness. 

u can go for damon braces system. its ideal option for u. it will convert your smile to broad celebrity smile.

You may be able to achieve some expansion of the back teeth with Invisalign and then after that place veneers to broaden your smile even more. And you could use the laser to remove some of  your gums on the back teeth to make your teeth look longer in the back, also further enhancing the broadness of your smile

Veneers are a quick way to almost instantly improve the buccal corridor.  A mock up is a must!The DNA Appliance will give a better result with or without veneers.  If you later decided to veneers they would be less bulky and more resistant to problems if the arch was expanded first.  Also less likely to collect food when you eat.Ira L Shapira DDS, D,ABDSM, D,AAPM, FICCMOThinkBetterLife.com
