The biggest complaint most people have about Invisalign is the constant maintenance and the “stop-and-go” nature of eating. Many users find it frustrating that they can no longer mindlessly snack throughout the day or sip on a beverage slowly. Every time you consume anything other than plain water, you have to find a bathroom, remove the trays, eat, brush your teeth, clean the trays, and put them back in. This routine can feel burdensome during work hours, at parties, or while traveling. Some patients also complain about the initial speech impediment, often a slight lisp, that occurs while the tongue adjusts to the thickness of the plastic. While these issues usually become second nature over time, the loss of dietary spontaneity remains a top grievance.
