Invisalign provides an alternative to traditional braces and does not have any brackets or wires. Invisalign uses clear aligner trays that are worn in a series over a specified amount of time and usually changed out weekly. The clear aligners gently move teeth into place, creating a beautiful smile. Invisalign trays are comfortable and smooth in the mouth. The aligners are almost invisible, making this a popular orthodontic option for both teens and adults.
