Can I get a crown if my teeth are in line? Trying to fix my smile without braces (Photo)

Do not do a crown.  I would tell you to do a bonded composite to begin with.  You will need to have a gingivectomy to remove gum tissue from #10 to have a good gingival contour on Smile line.  Results should be dramatic after a single visit.You can then decide how you you feel about the shape to your lip and tongue.I would recommend consider using a DNA Appliance to grow your jaws orthopdically and make room for that tooth.The DNA is removable and only worn 12-14 hours a day and is very comfortable.  If you dont crown the teeth  all options are still on the table.

Based on your photo, I would not have crowns placed.  I would have veneers placed instead, they are much more conservative.  If you have a dentist that is very experienced in cosmetics, you can correct the alignment of your teeth with restorations alone.  Additionally for you, I would recommend a gingivectomy (removal of gum tissue), above tooth #10 to complete your esthetic look.  Your canine protrudes but your lateral incisor (next to the canine) is also retruded.  I would recommend 8 veneers for you to broaden your smile.

I would agree with your dentist, I believe he/she has your best long term interest in mind.  You have beautiful teeth and you need to maintain that. There is nothing that can be done with crowns that will make the protruding canine not protrude, maybe less so but it is protruding in the bone and neck of the tooth and this will not change much.  The lateral incisor that is set back, if crowned, will have a large portion of porcelain on the front to give the appearance that the tooth is more forward.  This typically never looks normal and is difficult to clean and maintain.  I would HIGHLY advise you to see an orthodontist for braces/Invisalign and have the teeth straitened.  This will give you the best long term result that you can keep for a lifetime.  After orthodontics you may need some gum tissue sculpting to make the gum line of your teeth more symmetrical.
