Invisalign Westfield - Learn more about Invisalign treatment from our Westfield dentist who has ten-plus years of experience in it. In the past decade, there has been a strong push to make orthodontic treatment more discreet. The first advance was the development of clear brackets and wires. This improvement met the need for a less noticeable process, but still had disadvantages. Orthodontic treatment really advanced was when the aligner method of straightening teeth became available. Invisalign is a system designed to straighten teeth not only in the most discreet way, but also in the way that is most comfortable. Correcting misalignment with aligners has a number of benefits for the teen or adult who can commit to wearing appliances at least 22 hours a day.
