Genetics is one of the major causes of this dental condition. Most humans have more control over the shape, alignment, and size of their teeth than they do over the color of their skin or hair. Skin issues or hair loss may not be hereditary. However, if crooked teeth and dental crowding are common dental issues in your family, chances are you will also suffer from the same condition.

You might not be able to escape this condition if your parents suffer from it. The size of your mouth can also be determined by genetics. People with a smaller mouth are more likely to have crowded teeth.

Crowded teeth can result in the shifting of other teeth, causing your smile to lose alignment. If your jaws are not aligned properly, they can also affect your smile – usually the cause of overbite and underbite.

Poor Childhood Habits

Why is my upper lip crooked when I smile with my teeth? Well, you can also experience a crooked smile due to poor childhood habits. Children between the ages of 5 and 7 years tend to be at a higher risk of developing crooked teeth. The chances of developing crooked teeth are even higher if bad habits become the child’s routine.

Infants and toddlers are known to suck their thumbs, and it is acceptable at that tender age. This natural phenomenon occurs when they are trying to comfort or self-soothe themselves.

Nevertheless, if the child grows up with this habit until the permanent teeth start coming out, it might suffer permanent damage to the teeth. Once a child passes that infancy stage, prolonged thumb sucking can hurt permanent teeth, such as changing their position.

This bad childhood habit can cause overcrowding, a misaligned bite, and crooked teeth. It can also affect the shape of the mouth’s roof. If the shape of the mouth’s roof is affected, it can affect the individual’s speech, making it difficult to pronounce certain letters.

Facial or Oral Injury

Another common cause of crooked smiles is facial or oral injury. Why is my smile crooked after falling? The mouth is susceptible to all types of damages. According to data from Dentcare.com, over 5 million teeth are displaced from their gums every year. Sports injury is one of the major causes of this type of injury.

This type of injury can be minor or severe. In extreme cases, the injury might completely take out more than one tooth or shift the jaw’s position. In such cases, the remaining teeth would have to reposition themselves to cover the free space in the mouth. When this happens, the patient involved will have an imbalanced or misaligned smile.

Erosion of Gum Tissues

The gums are there to protect the teeth, ensuring they are firm in the jaws. According to a health report, almost 50 percent of American adults suffer from gum disease, so keeping your gum tissue healthy is always very important to protect your teeth.

Crooked teeth play a crucial role in the overall health of your gum. According to CDC, one of the significant risk factors of gum disease is misaligned bites. Misaligned teeth can add more stress to the alveolar bone and gums, resulting in gum recession and inflammation.

Cleaning Difficulty

Another common issue with this dental problem is difficulty in cleaning. People with crooked teeth find it very difficult to clean their teeth. When the teeth are crowded or overlapping each other, flossing or brushing them would become an issue.

This usually puts the patient at risk of tooth decay and gum disease. To prevent periodontal disease and cavities, people with crooked teeth need to be visiting their dentist regularly.

Difficulty in Chewing

Crooked or misaligned teeth also make chewing very difficult. People with misaligned bites usually find it difficult to break down food thoroughly before swallowing it. This can result in gastrointestinal problems.

Misaligned teeth can affect the way you eat, resulting in gassing, cramping, bloating, and stomach ulcers (in severe cases).

Tooth Sensitivity

This tooth condition also causes tooth sensitivity. When some teeth have worn out more than others, it can result in the exposure of the dentin – the softer tissue under the enamel of the teeth.

If you do not want to put on braces, you can opt for clear aligners. If your teeth are too short or chipped, then you should consider lengthening them with veneers.
