If primary teeth almost always develop straight, then why do some people have crooked teeth? What is the reason for having crooked teeth? Is it bad luck or coincidence? Or is it because of different factors that affect the oral cavity while growing? Our orthodontic team at Unionville Orthodontics will explain the reasons behind why crooked teeth happen.


According to the Canadian Association of Orthodontics, more than 4 million people in the United States and Canada are undergoing orthodontic treatment. What does this imply? It means many people have crooked teeth or a misaligned bite.

Crooked teeth can happen for many reasons. One reason is hereditary factors. Parents with crooked teeth, jaw problems, crowded teeth, and malocclusions have a higher chance of having children with crooked teeth. Poor and ill-fitting dental restorations of crowns and fillings can also cause crooked teeth. Early falling out of primary teeth, thumb sucking and tongue thrusting also contribute to the reason why some people have crooked teeth.

If you have crooked teeth or are looking to improve your smile – consult with an orthodontist for your best treatment options. Your orthodontist will take records of your teeth, and through that determine what type of treatment is best for you.
