Porcelain veneers are the golden standard procedure for a cosmetic dentist. We use veneers to correct many issues our patients have with their front teeth, including crowding. When your mouth doesn't have enough space for all of your teeth, many times the front ones will turn and overlap each other creating crowding. The best and most conservative way to fix this is to see an orthodontist for a consultation and see if Invisalign or braces can help. If wearing braces is not an option, or you've already gone thru orthodontics and your teeth have moved back, veneers may be the best choice. Porcelain veneers are a thin shell of porcelain that is permanently bonded to the front of your teeth. Minor teeth crowding is one of the major reasons our patients look to get veneers and in just 2 visits, you can have straight teeth! In addition to the immediate gratification, veneers can be used to permanently whiten you smile. Also, with veneers, your not moving the teeth, only making them look straight. This is important as you don't have to worry about your teeth moving back and having to wear a retainer for the rest of your life. Again, best option is to consult with an experienced cosmetic dentist who has successfully treated cases similar to yours. I would have a diagnostic wax-up made so you can see how much tooth structure needs to be removed in order to have straight teeth with veneers. The goal is to remove the least amount of tooth structure as possible for the best cosmetic outcome.
