The two front teeth are not equal, also have a wide gap in between them. What can I do? (Photo)

More photos would be very helpful.  (Along with a comprehensive exam and radiographs :)similar cases I have treated with great success included orthodontic movement of the teeth with Invisalign clear aligners along with a combination of fixed porcelain bridge (to replace the missing tooth and create proper aesthetic anatomy of the natural teeth, along with veneers and porcelain crowns.ps post some photos of the top teeth from a wide yawning position and some photos of the teeth in a full biting position from the left right and front 

Please see an orthodontist who can make a treatment plan for you. If guns are ok, braces can be done. 

It appears that you were either born without some of your permanent front teeth, or they were removed.  Whenever there is more space available, than the number of teeth to fill the space, teeth will move and drift.Good news....with cosmetic oriented dentistry, there are many solutions.  Are any teeth loose? The one that appears longer may be lose or have an abscess, as that is how they appear a lot of the time.  X-rays ,X-rays, X-rays will tell the story of how much bone these teeth have, are they solid and not loose, and have healthy gum around them.  Then we can talk about how to give you a beautiful smile. Veneers, bridges, implants, or removable partials are ALL POSSIBILITIES. A cosmetic dentist will diagnose the health of the teeth, and recommend the best way, or multiple ways to get you a full smile.  What's great about cosmetic dentistry.... We can use your teeth , and place veneers or crowns on them to make them appear a new shape and size. We can use the spacing and the teeth to create illusions that you have all of your teeth, and make your smile appear symmetrical and beautiful,  just like you had no spacing. So leave it up to a good cosmetic dentist to present various options, but there is no doubt that you can have a beautiful smile that no one suspected looked like this in the before photo! Key, is to go to a good adept cosmetic dentist, who will explain how to get you there. You should be presented several options, and explained to in detail, what it will look like, how much time it will take, and how you will appear in the "temporary" phase, the benefits of each, and the cost differences.  Use your gut.....and you will find yourself in a good office and will get a pleasing result. Good luck!!!  What looks to you, like a difficult smile to fix , looks to us like a perfect case to restore.
