Choices. Both invisalign & braces can provide you with a beautiful smile and each have their pros and cons. Invisalign will likely cost you more and take longer, but as an adult you may prefer how it looks while you are in treatment. It works by using plastic aligners that gently push your teeth with each tray, when they fit perfectly-- time to change trays so new ones push a bit more.
Don't understand. Don't understand question. Can you rephrase? If you're asking are clear aligners as good as braces, the answer is no. If you're considering straightening teeth/jaws, have consultation w fully qualified orthodontic specialist.
