Fishers Invisalign Dentist, Dr Michael O'Neil, has a new way to straighten teeth without braces. Invisalign uses a series of clear, removable Aligners to gradually straighten teeth, without metal or wires. But the benefits of Invisalign goes beyond just straightening teeth to provide that beautiful smile you have always wanted, it also provides for easier cleanings. Properly aligned teeth are easier to brush and floss which can lead to better oral health. Invisalign uses 3-D computer imaging technology to depict the complete treatment plan from the initial position to the final desired position from which a series of custom-made Aligners are produced.
