Invisalign has become one of the most popular orthodontic treatments, offering a discreet, removable alternative to traditional braces. Many patients love Invisalign for its convenience and ability to straighten teeth without metal brackets and wires. But like any dental treatment, Invisalign isn’t entirely free of potential complications. While most issues are minor and easily managed, it’s helpful to know what to watch for so you can address problems early and keep your treatment on track.
