Does invisalign hurt enamel

Invisalign does not normally damage enamel when monitored correctly, but plaque, decay, or a poor tray fit can cause problems.

Aligners move teeth through the periodontal ligament; the plastic covers enamel without filing it.

Plaque under a tray, untreated decay, or rough attachments can irritate teeth.

Brush with fluoride toothpaste, clean between teeth, rinse trays with cool water, and report sharp edges.

Seek care for persistent sensitivity, visible spots, pain, swelling, or a loose tooth.

Ask about decay, attachment removal, tray fit, and cleaning.
