What Are my Options Besides Traditional Braces? (16 Year Old Girl)

Without photos it is hard to make a treatment recommendation, but I would always recommend a consultation with an Orthodontist. At this appointment they will take photos, x-rays and do a dental exam. At this point, you can find out your treatment options. There is also an option called Invisalign that may be perfect for your concerns. It can be very effective in most cases and you have total control. That being said, it only works if you wear it.
Many orthodontists provide free consultation appointments as well.

Best of luck!

Like the previous doctors, without visually seeing how the teeth line up, the bite, and position of the jaws, a true treatment option could not be determined.  It sounds like you want to be in control of taking off or stopping treatment when you want to.  With any orthodontic treatment, you will have some uncomfortable periods because your teeth are actually moving into a different position.  Every one of my patients in invisalign patients understands that they have to wear them 22-23 hours per day.  If they do not, they will not get the results they want and will not be able to wear the next set of trays.  If any patient is not in compliance with wearing them, they risk having to start over and an additional fee for doing so.  So I would suggest you only get orthodontics when you feel ready to commit to the full treatment.  Good luck. 

Your daughter may have an active fraenum attachment above the 2 front teeth. The soft tissue is a muscle attachment that can pull the 2 teeth apart, creating the space.You should let your orthodontist assess this and Invisalign would be ideal for this small problem.I CERTAINLY WOULD NOT recommen veneers or bondings (that stain )

The only other option you have to straighten your teeth with something that is removable would be Invisalign, but your orthodontist would need to determine if your problem is correctible with it. Invisalign is limited at what it can do so it is not an option for everyone.

Without a photo its tough to tell.  Options might include Invisalign, veneers, or direct bonding to reshape the teeth and close the spaces.  my advice would be to discuss the above with your dentist.
