What Causes Some Teeth to Come in Crooked?

Crooked teeth aren’t uncommon, and unfortunately, the appearance of our teeth can make us beam with confidence or hide our teeth when we smile. With millions of people in the United States wearing braces, getting treatment for crooked teeth is normal.

But what exactly causes some teeth to come in crooked? You may have noticed some people have crooked teeth while others seem to have always had a straight smile. Here’s why some teeth may come in crooked.

Genetics

Crooked teeth are usually inherited and are related to a size difference between your upper and lower jaw or your jaw size and tooth size [1].

For instance, if your jaws don’t align correctly due to genetics, this can cause crooked teeth.

Some people don’t have enough room in their jaw for all the teeth to erupt comfortably through, and so will experience crooked teeth. Overcrowded teeth and a misaligned bite are the most common causes of crooked teeth!

Poor Jaw Development

There are several factors that can affect jaw development, and as we’ve just seen, a misaligned jaw can affect crooked teeth.

Mouth breathing can cause the jaw to develop incorrectly which can lead to teeth coming in improperly [2]. Trauma to the jaw during childhood can also cause issues with development, as can birth defects such as cleft palate [3].

When the jaw doesn’t develop properly, teeth are more likely to be misaligned.

Thumb Sucking

Habits during kids’ early years can impact tooth development as their primary teeth come in.

Remember, baby teeth guide permanent teeth in, so if the baby teeth come in crooked, there’s a good chance the adult teeth will as well.

For instance, children who suck their thumbs into their toddler years may have teeth that grow in crooked to accommodate this habit. Children who use a pacifier past the age of three or use a bottle past this age are also more at risk to have crooked teeth.

Losing Baby Teeth Too Soon

Loosing the primary teeth too soon can cause the permanent teeth to shift before theyeven have a chance to erupt.

Baby teeth may be lost too soon due to tooth decay or injury. Since baby teeth hold the place for permanent teeth, this can affect their adult tooth development [4] and causeteeth to come in crooked.

Caring for your child’s baby teeth gives them their best chance to have healthy and straight
adult teeth as they grow up!
