5 Reasons Why Teeth Are Crooked

Most of us don’t have the good fortune of having naturally straight teeth. In fact, crooked teeth are extremely common and many people have at least one or two misaligned teeth. But what exactly causes crooked teeth and why do so many of us end up in the dentist’s chair getting orthodontic treatment? Here are a few of the most common factors that affect the alignment of teeth, some of which you may find surprising:

Your Jaw

When the jaw develops unevenly, the awkward angle causes teeth to crowd or come in crookedly. While this is often a matter of genetics, there are also theories that attribute conditions like mouth breathing due to asthma and allergies as affecting proper jaw development.

Your Palate

If the roof of your mouth is broad and U-shaped with a low arch, your teeth have plenty of room to grow in and are less likely to be crowded. However, if you have a narrow, V-shaped palate it gives your teeth less space. The shape of your palate is related to your jaw so this is usually determined by genetics as well.

Your Tongue

The human tongue is an exceptionally strong muscle, and it has the ability to shift the position of the teeth over time. By applying constant and repeated pressure against the teeth (a habit known as tongue thrusting), they can gradually be pushed out of place.

Your Habits

Thumb sucking, prolonged use of a bottle, or using a pacifier beyond the age of two can affect the position of both baby and adult teeth. It’s also important to prevent the early loss of baby teeth due to poor dental care since these primary teeth act as placeholders for adult teeth.

Your Age

It’s no secret that our bodies change as we age and our teeth are no exception. Over time, the muscles in our mouths loosen and our teeth gradually begin to shift, especially if there are spaces due to tooth loss.
