Approximately four million Americans, particularly teenagers and adolescents, wear braces at any given time. Of course, no one wears braces for fun or as a fashion accessory. Braces are a corrective measure for periodontal conditions like overbite, underbite, and crooked teeth. 

For most people, perfectly straight teeth complete with that Hollywood smile are only the product of dreams. If you’re not so lucky to have straight teeth, you might be wondering what causes crooked teeth? 

Well, there’s no single reason for crooked teeth but a number of them. Fortunately, there are a few corrective measures for both crooked and misaligned teeth. So crooked teeth aren’t something you should lose sleep over.

In today’s post, we’ll be highlighting the few causes of crooked teeth and what crooked teeth treatments you can opt for to address the situation.

1. Genetics

Most people ask, “Is crooked teeth genetic?” The short answer is yes, but there’s more to it.

Some crooked teeth issues run down the family. Maybe your parents have crooked teeth, and that’s why yours are also crooked. Sometimes the genetic link isn’t as obvious as you’d think; perhaps it’s something you got from your great grandfather.

If crooked teeth run in the family, there’s a high likelihood that your children will also have the same. Even diligent oral habits can do nothing to sidestep having crooked teeth. However, you can look into a few teeth correction methods to address the issue.

2. Thumb Sucking

Thumb sucking is a seemingly harmless habit among toddlers that also leads to crooked teeth. The constant pressure the child applies on the growing teeth leads to protruded upper teeth or overbite. 

A little thumb sucking isn’t something to be worried about. The problem comes when the thumb sucking prolongs for a few years. Children stop sucking their thumbs at about seven to eight months. You can check out these few tips on how to stop thumb sucking to help your child break the habit.

3. Tongue Thrusting

Just like thumb sucking, tongue thrusting also applies pressure to the upper gum where your teeth grow. This has the same results as thumb sucking and leads to overbite and protruded upper teeth. 

4. Childhood Facial injury

Severe facial injury during childhood is detrimental to one’s tooth alignment. Most childhood jaw injuries result in tooth displacement and misaligned teeth. This happens when the jaw shifts from its position and results in crooked teeth growth.

Some childhood facial injuries result in tooth loss that also amounts to crooked teeth. This happens because the tooth grows to cover the empty gap in the gum. The result is crooked and misaligned teeth. 

5. Malocclusion

Malocclusion is a dental condition where you’re upper and lower jaw don’t align. Malocclusion causes overbite and underbite. Overbite is when the upper teeth protrude over the lower ones, while underbite is when the lower teeth do the same.

6. Poor Dental Hygiene

Poor oral habits, especially at a younger age, increases your risk of getting gingivitis. Gingivitis could progress into periodontitis, which is a severe form of gum disease. 

Periodontitis affects the way your teeth grow and may lead to crooked teeth. In very severe cases, periodontitis may cause your teeth to fall out. 

7. Malnutrition

A balanced diet is imperative for proper bone and teeth formation, especially in infants. Aside from poor health and stunted growth, malnutrition in children can also lead to crooked teeth. That’s because the body doesn’t have sufficient nutrients to facilitate proper teeth growth.

8. Early Tooth Loss

Children start to lose their baby or milk teeth at about age six. Anything earlier and the teeth your child grows could be crooked. That’s because other teeth may shift into the open spaces and grow improperly.

However, not all early tooth loss cases result in crooked teeth. However, it’s a good idea to talk to your dentist if your child’s teeth start dropping a bit too early.

9. Mouth Breathing

Believe it or not, breathing through the mouth can also lead to misaligned teeth. Excessive mouth breathing in children can have adverse effects on their teeth alignment.

How to Straighten Crooked Teeth

As mentioned earlier, there a few corrective measures you can opt for to straighten your teeth. Remember, crooked teeth transcend more than just the physical. Some folks might ask, “Are crooked teeth bad for your health?” well, yes, they are.

Crooked teeth lead to excessive wear and tear of teeth because of improper chewing. This also results in jaw strain and temporomandibular joint disorder. Crooked teeth also lead to periodontal diseases because they are harder to clean.

With that out of the way, here are the major treatments for crooked teeth:


As you might’ve guessed, braces are the most effective treatment for crooked teeth. Braces consist of brackets, bands, and wires. These braces apply pressure on your teeth and jaw to make them adapt to a specific pressure condition. This makes the teeth move and grow in a particular direction.

There are many types of braces including, ceramic braces, lingual braces, and metal braces. Discuss with your orthodontist to figure out what kind of braces work for you.


If braces are too all-over-the-place, you can settle for Invisalign®. Invisalign® is a fancy term for invisible braces for self-conscious individuals. Invisalign® is way less noticeable than ordinary braces but works just as well.

Invisalign® treatment starts with transparent trays that the orthodontist creates to fit over your teeth. The orthodontist creates several molds that you’ll change over time until your teeth finally move in their correct position. 

Most adults opt for Invisalign® because it’s much less noticeable. Invisalign® treatment costs much more than braces. Still, most adults are willing to make the financial sacrifice and get Invisalign®.
