Let's Talk Teeth
Invisalign is great option in most cases. Invisalign is a successful at straightening teeth as regular braces. I recommend scheduling a consultation with a local Invisalign provider. They will gather the necessary diagnostic information to determine the most suitable treatment for your individual needs.
Straighter smile options
Great question--when teeth are misaligned the best way to get them appearing straighter is usually to align them orthodontically with braces or invisalign or other alignment systems.That said you could also have a straighter smile by reduction and addition procedures--this means using porcelain or bonded composite to reshape and contour the teeth into better esthetic and functional alignment. See a good cosmetic dentist and orthodontist to weigh out your options --time and price typically can be a factor as well but not always-good luck
