While I understand that you don't want braces, in an effort to provide you with all options, I wouldn't be thorough if I didn't at least mention why orthodontic treatment may be the best way to treat a gap between your teeth. Orthodontic treatment, you see, is the least damaging to your actual teeth since, in the majority of cases, no "prep" work is needed to place them on. If it's the actual silver color of the brackets are the turn off, keep in mind that there are now clear braces available as a more invisible option. Other orthodontic techniques with no brackets are Invisalign or Clear Correct. Both of these, use a system of trays to correct any mis-alignment or teeth gap issues. And now to non-ortho options. Veneers or Composite restorations (tooth-colored fillings) are 2 very easy and fast ways to close that gap. Veneers are lab processed restorations that are placed over prepared teeth and usually accomplished in as little as 2 appointments. Veneers will never change color and the lab following the dentist's precise instructions can make your teeth absolutely beautiful and natural looking. Of course, they are also more expensive than the second option: composite build-ups. Composite Restorations provide you with not only a beautiful result, but a quick one as well - only 1 appointment needed. However, these restorations will discolor and chip over time and will need to be replaced. Any way you decide, please remember you must find a dentist not only well experienced in the knowledge of these techniques, but one that also understands and has thorough knowledge of how your bite, habits, facial structure, coloration and other factors can lead to, in the majority of cases, predictable results.
