At Douglas Knight Orthodontics, our mission is to help patients throughout Tacoma, WA and the surrounding areas achieve straight teeth and a beautiful smile through orthodontic treatment. But while many of us know we need orthodontic treatment to fix crooked teeth, the root cause of the problem is often less obvious. Many of our patients wonder: what causes crooked teeth in the first place? As your dedicated Tacoma orthodontist, we strive to be a resource for both orthodontic treatment and education. So we'd like to shed a little light on the causes of crooked teeth.
