My two front teeth overlap due to overcrowding. Is dental bonding the answer? (photo)

Bonding will give you an immediate improvement and it can be done non-invasively in a single visit.  The overcrowding is not due to your wisdom teeth., though this common fallacy is frequently cited. The third molars do not push the other teeth forward. They do erupt passively until contact is made with another tooth.   Crowding is  due to insufficient arch length for your teeth.  The best results would probably be orthodontic.  If additional arch length is needed the DNA Appliance is probably the best solution in adults for orthopedic growth with an appliance worn during sleep plus a few extra hours a day.  The DNA Appliance will involve more cost in the short run but will give the best long term results.

Yes it will but remember that bondings and resins, sooner or later will change color,so that would be temporary, are you thinking to change that material continuously?how soon, it depends on your way of eating,think on braces, or veneers, this would help more. I hope this helps.
