This patient had a few different issues including crowding, crossbite, and an edge-to-edge bite. This caused a few different problems like buildup of plaque and tartar that harbors harmful periodontal bacteria, premature tooth wear and risk of chipped teeth, abfraction--small notch in tooth at the gumline, jaw joint pain, risk of periodontal disease, tooth, and bone loss. After one year of Invisalign treatment, the teeth have aligned properly for a healthier mouth.
