Will Fast Braces Work for Me (Overbite, Teeth Spread Out)?

Depending on your goal, most forms of orthodontics can work.  If you are trying to open up the space that was lost when the tooth came out, then it will take time and be pretty involved.  Since you have a crossbite, where the lower teeth stick out overlapping the uppers (reverse of ideal), I don't think a "fast" solution should be priority.  It is possible that the result happens faster than anticipated, but you may sacrifice the quality result for the sake of speed.

If you just want things lined up better, and the canine (eye tooth) to be in the lateral spot (where the permanent one never came in), then even 6 Month Smiles® can work.

Hi!
When you lose a tooth in the front, your midline shifts a lot to that side. In your case, the midline is shifted to your left side. I would open that lost space, and make sure the midline of your teeth matches the midline with your face. Otherwise your smile will never look symmetrical. With your missing tooth, crossbite of the lower canine, upper spacing and lower crowding, I would definitely see an orthodontist for full treatment, and NOT a general dentist who is doing Fast Braces.

There are two options when you are missing a front tooth, replace it or close the space. The decision is influenced by the amount of crowding, the bite relationship, and the position of the lips. If there is no other reason to remove a tooth, it is usually best to re-open the space and replace the missing one with a bridge or an implant. If there is crowding or an overbite, then the space can be closed. Either way, the detailing that will be necessary will best be accomplished by conventional orthdontics. Good luck!
