National Align Your Teeth Day is observed in the United States every August 11. Established by the American Academy of Clear Aligners (AACA) in 2021, this day aims to promote the benefits of orthodontic treatment and encourage individuals to consider teeth alignment options. The date commemorates the birthday of Dr. David Galler, a pioneer in clear aligner therapy. Misaligned teeth can lead to difficulties in oral hygiene, chewing, and speech, highlighting the importance of orthodontic care. On this day, people are encouraged to schedule dental appointments to assess their orthodontic needs and share their experiences on social media using the hashtags #NationalAlignYourTeethDay and #AlignYourTeethDay.
